Abstract
This study aimed to investigate the temporal-spatial and synoptic features of thunderstorms in southwest of Iran (Khuzestan, Chaharmahal & Bakhtiari and Kohkiluyeh & Boyerahmad Provinces) It was compiled using volatility indices during the period 1985-2015. Results of Frequency Analysis of Thunderstorms at Dezful Station with 479 cases the highest frequency and Ramhormes with 252 days had the lowest frequency. In terms of seasonal distribution, spring was the most abundant with 39%. On a monthly basis, April had the lowest frequency with 21% and August with only 2 cases. In terms of thunderstorms the highest frequency of thunderstorms with no thunder was 21 percent. Synoptic analysis: Most of the time there is a nave (at level 500) or low pressure in the west of the region, east of the Mediterranean Sea with its tabs clockwise. From the Red Sea and the Persian Gulf, they entered the south, southwest, and west of Iran On the other hand, the high-pressure system on the Gulf of Aden in the east of the region is round in the clock It has injected moisture, especially at a level of 850 millibars. Interaction between the two systems over the course of the day, It has injected moisture from three sources of the Mediterranean Sea, the Red Sea and then the Persian Gulf into the rising systems of the region. The low-pressure counterclockwise movement of the eastern Mediterranean, Along with the high-altitude clock movement over the Gulf of Aden, it has injected moisture at levels of 850 to 700 degrees.

Abstract
This study investigates the subtropical anticyclones and summer monsoons of the north hemisphere in the 500 hPa level, effective on Iran in a 38-year period (1975-2012). For this purpose, the data of geopotential heights of 500 hPa at 12 UTC with a spatial resolution of 2 by 2 degrees of the (NCEP/NCAR) were used. Results show that three independent patterns (Azores anticyclone, Saudi anticyclone and North West Africa anticyclone) and four combinatory patterns derived from the independent patterns have controlled the atmosphere of 500 hPa level of Iran. In most cases, the maximum in geopotential heights in above-mentioned anticyclone centers reach to more than 5920 geopotential meters, but often the tongue of these anticyclones control the atmosphere of 500 hPa levels of Iran with the geopotential height of 5880 to 5900 meters. In contrast, at this pressure level, the large-scale monsoon system is very weak and the maximum geopotential height of this system is about 5840 meters. The extent and intensity of the monsoon system has been reduced so that its tongues do not affect the 500 hPa level of Iran at any time. Given that the main factor in the development of large-scale monsoon system is the surface heating (bottom-up formation) and the main factor in the development of subtropical anticyclone is descending of atmospheric dynamics, the main reason for the development of summertime subtropical dynamic anticyclone should be a very strong and unit agent, something other than the summer monsoons.

Abstract
In this research, coding the rainfalls, prepares daily 45 stations with the statistical period of 20 years to zero and one codes to realize the daily dry periods in west and north west of the country and then, by establishing the main condition of occurrence of code one for 30 stations, we extracted the dry 4 to 10-day frequencies. And the results gained of considering the atmospheric weathering, shows that the most clear rotational pattern in sea level is related to Siberia-Europe high-pressure panels and sometimes both of them that increase the rotation on the region and also, the local high-pressure reinforcement and there is a high altitude in atmospheric middle level which is derived from sample patterns and is placed on the studied region and these sample patterns are from omega, bi-polar and rex models that they are on Russia and Scandinavian countries with some changes. The 500 level TAVA and omega shows well that in most regions, the air course, has decreasing case and so, we can result that placement of a high altitude in atmospheric middle and upper level on the high-pressures of the earth, causes the weather stability and lack of rainfall and as a result, the stability and durability of these conditions for several days, is related to sample patterns.

Abstract
One of the issues facing today's cities in Iran is the issue of maintaining and upgrading existing streets. The way of managing theses streets and dealing with them has caused various problems in different aspects of cities. The purpose of this research is investigating the principles of maintenance and promotion of urban streets with a focus on Islamic teachings and Iranian culture. This research also explains some ways to improve the quality of urban streets using Islamic teachings and Iranian culture. Gathering information was done through observation, field study and documentary studies. Using content analysis methods, documenting and graphical analysis, information and data were analyzed. The quality of the cities depends on the quality of the streets and the quality of the streets is also based on the details of the streets. After designing and constructing urban streets, they need attention, maintenance and promotion in order to be always attractive and desirable for citizens. The results of this study indicate neglecting the indigenous material, art, culture, religion, needs and interests of citizens which has led to the construction of unqualified urban spaces in the metropolitan areas of today's Iranian cities. This research did not seek to provide a template for urban streets designing, but it is in direction of developing principles of planning and designing urban streets based on Islamic teachings and Iranian culture. In addition to having appearances according to Islamic teachings and Iranian culture, desirable street for Iranian citizens should also be Islamic and Iranian internally. With Just the correctness of appearances it can be said that only hypocrisy is obtained, but with internal reforming, honesty can be created in urban spaces.

Abstract
In the contemporary century, with increasing development of technology, one of the challenges of contemporary architecture is to find its relationship with the culture. New technologies from industrialized countries with developmental goals are imported in an uncontrolled process. In contemporary Iranian architecture, technology has had a serious presence in various fields. The main purpose of the research was to investigate the cultural transformation of contemporary buildings in Tehran according to the application of technology. Due to the variety of types of use, this study focused on official complex compared to the two periods before and after the Islamic Revolution.The research method used in this research is combined (quantitative-qualitative). First, the components of technology and culture in accordance with contemporary architecture in the office buildings of Tehran have been developed by qualitative research method, then by quantitative research method, the relationship between key factors involved and the share of each component has been investigated. To examine the hypothesis, the relationship of three variables of culture, technology and architecture has been identified. In this study, cultural developments have been evaluated in two dimensions: mental and objective components. The results show that the effects of metamorphosis have had the greatest impact on the objective components of culture, including individual and social strata.Finally, the issue of technology application in contemporary office buildings in Tehran with a culture-based approach has been proposed in the form of a strategic model that will lead to the correct application of technology in office buildings in Tehran.

Abstract
The purpose of this research is to identify changes in the temperature trend in the western half of Iran. For this purpose, monthly temperature data of 15 synoptic stations were collected during 1960-2010. Quality control was applied on these data by applying Pettit, SNHT, Buishand and Von Neumann’s tests. Later data Simulated and compared with reanalysis data such as ERA-Interim, ERA-20C, NCEP and CMIP5 models (RCP8.5 for the period 1960-2100). Trends were calculated by the Mean Kendall test and the Sen’s estimator (95 % confidence level). Based on the results obtained from all models, a significant positive trend was observed in spring, summer and autumn, and only in winter according to ERA-Interim. Based on CMIP5 results for the period 2050-2100 values between 2 and 4 ° C/100 achieved, which is lower than the results of other models for the period 1979-2010. Considering the CMIP5 models and their overall average in the study area, an increase in annual temperature (7 ° C /100) for the second half of the 21st century was confirmed.

Abstract
The purpose of this study is to determine the long-term variations in rainfall data as well as to identify wet and dry periods of 35 synoptic stations in Iran. In order to know the variation of rainfall in studied stations, average maps, coefficient of variation and skewness were drawn. Then, using the Mann-Kendall test, the significance of the trend on each station was tested at 95% confidence level. Finally, wet and dry periods were identified by using 20% high and low extreme rainfall during the 50-year study period. The results show that the general model of the country's regime is that the rainfall levels from the north to the south-east and from the west to the east of the country are reduced. The lowest values of the coefficient of variation and skewness are related to the northern regions especially the Caspian seaside and the highest amounts are in the southern regions, especially in the south and south-east. In general, the results of the Mann-Kendall test show that rainfall data in the seasonal scale, with the exception of several synoptic stations, do not show a significant trend. Most wet periods occur in the spring and the lowest in summer and the highest dry periods occur in the autumn and the lowest in spring. The number of droughts in the cold periods is significant. Also, the frequency of occurrence of dry periods is more than wet periods.

Abstract
Dates are one of the most important agricultural products exported from Iran. This plant is sensitive to environmental conditions and is not able to live and reproduce in all hot and dry areas in terms of quantity and quality. Dates have different varieties; each of them has the potential to adapt to a region of arid regions and can have the most production and economic yield in its proper place. Global warming in the last century has led planners to design pre-awareness programs and algorithms due to future climatic conditions in order to choose long-lived durable plants that can survive in future environmental conditions and have good economic yield. One of the best is the Maximum Entropy model. The aim of the present study is to identify the growth potentials of dates palm verities using CCSM4 model and scenarios of 2.6, 4.5, 0.6 and 8.5. The phonological data of cultivars were harvested by field method in 2016 and 2017. According to the model, The results showed that the dates of Astamaran and Berhi dates are different in terms of the length of phonological growth and thermal needs until the fruit ripened, and the places prone to their growth during the 2050 and 2070 periods were not the same based on the model. In addition, to bioclimatic variables for the long-term use of long-lived perennial crops, the location data required for cultivation should be used to introduce different cultivars to the environment.

Abstract
The aim of this study is to identify and rank entrepreneurial opportunities in sports tourism based on geographical capabilities and capacities in Iran. The present study was descriptive-survey and was performed by mixed method. Data collection in this study was done in two stages. In the first phase, a list of entrepreneurial opportunities of sports tourism was identified through a search of previous research, as well as interviews with 17 people. In the next step, experts' opinions on these statements were obtained using the Delphi method. Finally, eight subfields of entrepreneurial opportunities are ranked based on Iran's geographical capacity in four temperate and humid climates, hot and humid, cold and mountainous, hot and dry, using a software program and a multivariate regression test. Based on the results, it can be said that along with economic, political, cultural factors, etc., the diversity of climate and geographical capacities is effective in the emergence and selection of opportunities. By analyzing the data, we can say that each of these opportunities has been used with different levels in Iran's four climates. Some opportunities in one climate take precedence over others. Authorities of tourism and sport in their short-term and long-term planning and planning should be instrumental in improving sport tourism by these opportunities.

Abstract
Precipitation is a phenomenon resulting from complex atmospheric interactions and among climatic events, due to its vital role, it has special importance. The importance of precipitation durability, especially in arid and semi-arid regions, which includes most of Iran, is greater than its volume. The purpose of this study is to identify Iran's precipitation areas in terms of precipitation durability and its characteristics in each area. In order to investigate the durability of Iran's precipitation and to define a precipitation day as " a day with equal precipitation or greater than 0.5 mm", used from daily precipitation data of 80 synoptic stations of the country during the 6 cold months of the year from October to March in a period of 30 years (2016 - 1987). Setting data in daily tables in the first step, made possible to program in MATLAB environment to separate precipitation in ten groups from "one day" to "ten days" and in the second step in SPSS environment based on frequency characteristics, amount and precipitations average in the mentioned groups was done by the method of Ward merging and clustering. The process of the clustering on Iran's durability precipitation showed that there are seven almost homogeneous precipitation zones in Iran; the geographical arrangement of Iran's precipitation areas, reveals the dependence of Iran's precipitations amount on roughness, the path of precipitation systems, its proximity to humidity sources, and the effect of the sea. In terms of area’s location, it can be said that; the settlement of the four zones in the western half of Iran, despite its small size in front of the eastern half, is a reason for its heterogeneity.

Abstract
The aim of the present study is to dynamically model the spatial-temporal characteristics of dust in the south and southeast of Iran with REG-CM4 model using monthly dust data and RegCM4 data. For this purpose, the dust distribution of the IDW method along with the dust diagrams were plotted. The RegCM4 model was implemented with the paired Lambert image imaging system for 40 km horizontal separation with the paired chemistry model. The location of monthly and annual dust distribution shows the highest amounts of dust for the cities of Zabol, Bandar Abbas, Zahedan and Jask compared to Sirjan, Kahnooj and Lar stations. The highest frequency of dust in Sistan and Baluchestan (48%), Hormozgan (27%) and Fars provinces with 16% and the lowest frequency for Kerman province (9%). In general, the summer seasons (at Sistan station) and the winter (Kerman station) have the highest and minimum dust events, respectively. The time survey also has the highest amount of dust for the warm months of the year and the lowest for the cold months of the year. July at Zabol station and November and December at Sirjan station have the highest and lowest dust levels, respectively. The RegCM4 climate model also shows maximum dust on the southeast, south and south coasts for different variables.

Abstract
Climate change, including spatial changes in rainfall following the increase in greenhouse gases, is a challenge that affects various aspects of life in human societies today. In this study, the long-term spatial changes of the rainy season from September to May were studied using the statistics of "local Moran" and "Hot spots of Getis Ord-J" during 5 5-year periods from 1991 to 2015. The application of local Moran statistics showed that areas with long rainfall periods are in good agreement with the countrychr('39')s rainfall pattern. This adaptation is accompanied by a negative spatial correlation in lands with short rainfall periods. The pattern obtained from the hot spot statistics also showed itself to be more consistent and corresponded to two very low rainfall regimes in the southeast and center, while according to local Moran statistics, this pattern was more scattered and parts of it had a low southern precipitation regime. . In addition, the results of Alexandersonchr('39')s statistics to identify mutations in the long-term series of the rainy season showed that the time series of 13 stations out of 108 stations studied experienced a sudden jump that these mutations are more in the southern stations in the country and in later years. It has occurred since 2000 AD.

Abstract
Rural indigenous entrepreneurship is one of the youngest research areas to show that in Iran, one of the largest countries in Asia and has rich cultural heritage and indigenous communities, the issue of native rural entrepreneurship has not been addressed so far. Therefore, the present article, as an analytical assessment and with a variety of approaches based on richness and conceptual diversity in the fields of social sciences, economic, planning and rural development, uses a systematic approach, while introducing entrepreneurship while introducing entrepreneurship. Rural native to introduce native rural entrepreneurship to the context of future research in the country. This article contributes to a comprehensive understanding of native entrepreneurship research by analyzing literature and research lines. In this regard, the present article, which is intended for the purpose and information provided by the documentary method, sought to answer the questions about what elements of the difference between native rural entrepreneurship and classical entrepreneurship? What are the unique goals and characteristics of rural native entrepreneurship? And what are the (model) pattern for the development of native rural entrepreneurship in Iran? The results of the study indicate that indigenous entrepreneurship is different from classical/ Western entrepreneurship, and emphasizes elements such as the use of indigenous resources, indigenous cultural values, collective interest, family relationships and family/ family ties. The results showed that rural native entrepreneurship is not necessarily in response to market needs and is mostly aimed at providing family livelihoods, environmental protection, cultural and spiritual value. Unlike Western-style entrepreneurship, rural native entrepreneurship shows elements of equality-equality, collective/kinship activity, and emphasis on available cultural values and natural resources. Rural indigenous entrepreneurship is often carried out with intra -household livelihoods and mostly with non -economic goals such as preserving livelihoods, preserving indigenous culture, protecting the environment and spiritual goals.

Abstract
The position of the Tigris and Euphrates rivers is in the least compatible with national borders or with the political and strategic considerations of regional countries. The sources of the Tigris and Euphrates rivers are located in Turkey, and Turkish authorities believe they own the resources. A project called "Gap" or "Anatolian" in the framework of the construction of more than 22 dams and 19 hydroelectric projects and development of the agricultural system in the Tigris and Euphrates watersheds has been on the Turkish governmentchr('39')s agenda by 2023, reflecting the security threat. The environmental and water security of the downstream countries (Iraq, Syria and Iran) have been demonstrated. The present study is based on the assumption of reflecting the Hydropolitic relations of the Tigris and Euphrates basin (based on Gap Project) with the viewpoint of continuing climate change and changing rainfall patterns and increasing water use in downstream countries using library resources. In the form of a threat to the security of the southwestern areas of Iran, it will intensify. The results showed that the consequences of the Hydropolitic approach of the Tigris and Euphrates countries, especially Turkey, besides threatening environmental security, affect other aspects of security in the economic, social and political spheres in the southwest of the country.

Abstract
Due to its location in low latitudes, Iran is among the countries that has not been spared from the security consequences of climate change. The present study seeks to answer two questions: 1) What are the security consequences of climate change on Iran and which components have the greatest impact on Iran? 2) Which of the pillars of good governance as a solution has the greatest impact on reducing the effects of climate change on Iran?
In this study, the study population is elites and experts familiar with the subject of the study, 100 of whom were selected for snowball sampling and a researcher-developed questionnaire was used to collect data. Data were evaluated using SPSS and MINITAB software. The results of the studies according to the obtained P-value which is equal to 0.000 and is less than 0.05 alpha, indicate the difference between the natural and human consequences of climate change in Iran. The results of the Tukey test indicate that the natural consequences of climate change with an average of 4.0584 are in group A and the human consequences with an average of 3.4460 are in group B. Also, the results of Friedman test on the effect of good governance in controlling and reducing the security consequences of climate change in Iran show that accountability with an average of 5.79 in the first place, rule of law with an average of 5.62 in the second place. and accountability of officials with an average rating of 5.32 are in third place.

Abstract
The current research is based on the process of algorithmic design and simulation of village boundaries using the Grasshopper plugin in the Rhino software. The proposed algorithm utilizes the image simulator component and its importer in the Grasshopper plugin to input two-dimensional images taken from samples into this plugin. Before entering the data, the input images are converted to black and white to allow the system to distinguish between the background texture and the subject of analysis. Additionally, the proposed algorithm identifies the village boundary by comparing the subject and the text in the pixels of the two-dimensional image. By calculating the internal area of the identified boundary, the algorithm estimates the proportion of textures relative to the background. The main objective of this research is to examine the impact of green and dry textures as natural factors on the density of residential texture in terraced villages in Iran, across various climates. In addition to identifying the density of village textures, emphasizing the comparison of parameters will provide new insights into the texture of terraced villages. The simulation analysis tool, known as the density measurement algorithm, is developed based on aerial maps created by the researchers for this study. By using inverted aerial maps, this algorithm can determine the density of natural texture in the formation of villages and residential texture. This capability reduces the need for physical presence and enhances the accuracy of outputs in analyzing village texture. Furthermore, the identification of parameters will provide the next generation of rural housing with the density pattern of previous generations.

Abstract
Factors and stimuli that influence convergence and divergence play a crucial role in determining the process and quality of national cohesion. These factors and stimuli are not synonymous; rather, they are interconnected and mutually influential variables. Understanding the impact of convergence and national cohesion on overall security is of utmost importance. This study aims to investigate and analyze the factors and stimuli that affect national convergence and cohesion in the southeastern region of the country. Similarly, this article seeks to address the fundamental question of the primary factors and stimuli that influence convergence and cohesion among the Baloch people in the southeast. The research findings indicate that various factors significantly impact the convergence and divergence of the Baloch people in the Sistan and Baluchestan province. These factors can be classified into two categories: internal and external stimuli. The study underscores the significance of factors such as mutual trust, decentralization, concentration of industries and decision-making centers, strengthening ethnic identity in alignment with national identity, the role of historical documents in promoting national cohesion, the cultural center of the Baloch people in southeastern Iran, common social customs, and the positive influence of ethnic and national elites. Additionally, the study recognizes the influence of regional political tensions, historical economic ties with neighboring countries, and the prevalence of border markets with Afghanistan and Pakistan as significant factors that shape convergence, divergence, and national cohesion among the Baloch people in the Sistan and Baluchestan province in the southeast of the country.
