The way pressure is distributed on sea level and geopotential height in different layers of atmosphere influence climatic and meteorological phenomena on the surface of the Earth. One of the important meteorological phenomena is the freezing especially late spring freezing. In this paper, late spring freezing days and the minimum temperature have been recognized using minimum daily temperature during 1960 – 2005 in Najafabad station. Also, sea level pressure and geopotential height patterns in 850, 700 and 500 HP in Asia, Europe and North Africa have been illustrated. The relationship between Najafabad freezing and weather patterns in different atmospheric layers has been studied afterwards. The findings show that there is a relationship between Najafabad freezing and weather patterns in different atmospheric layers. In conclusion, through formation and spread of Siberia high, air temperature decreases in Najafabad and sometimes it falls below 0 c. Inequality and the lack of balance among different geographical areas, made inevitable the necessity of attention to the spatial planning. On this basis, Fereidoonshahr is taken as for the case study. This study aims at the recognition of inequality and the lack of balance among different rural districts of this township. The methodology is qualitative- analytical. With a view to having different indexes of development, the findings show that there is an inequality and lack of balance among the rural districts of Fereidoonshahr. In this inequality, Barfanbar, Poshtkooh-Mogooei, Cheshmelangan and Pishkooh-Mogooei take the first to fourth levels respectively. The Middle East region has always been important in political developments and strategy- taking by global powers.The increasing importance of Middle East region with regard to strategic and geostrategic issues has been crystal clear in the viewpoints and strategy of global powers, especially the US during the past decades.Therefore, to homogenize this region, the US government has brought under consideration the large Middle East Plan, (with the pretext of) under the disguise of apparently sowing the seeds of democracy, but actually plundering the energy of the region. Thus, while introducing the importance of the region and its influence on global issues, this article investigates the aims of US and Zionist regime in representing the large Middle East Plan with a geographic viewpoint. Feminism is a school that of thought investigates inequality between men and women Feminists believe that this should change and women must not be exposed to gender discrimination and oppression. School of feminist geography points to numerous ways that gender and spaces are created reciprocally and feminist geography studies ways that space has been distinguished by gender in them and geography investigates what has been happened in this field. Of course, gender thoughts have long history and different religions have mentioned this. In this paper feminist geography, types of feminism, their attitudes and also feminism school with their problems have been investigated in different countries.Generally, all spatial distribution maps illustrate a decline in thunderstorm activities from west to east and from southwest to northeast of Northwest Iran because of individual or synchronous physiographic effects, synoptic systems and climatic factors. Thunderstorm rainfall is considered as a very vital climatic factor because of its significant effects and often disastrous consequences upon people and the natural environment in the Northwest of Iran. The previous findings have shown that thunderstorm rainfalls occur often in spring and summer seasons and during afternoon and the early evening. Accordingly, the main purpose of current study was the investigation of spatial distribution of thunderstorm rainfalls in the Northwest of Iran by applying gamma function on the available data in the yearly and seasonal (spring and summer) scales. With this aim, initial daily thunderstorm rainfall data observed from 16 synoptic stations have been analyzed. Cluster analysis method is used for station clustering, gamma distribution for description and briefing and ArcView for spatial distribution mapping of thunderstorm rainfalls. 1-Asistant Professor, Islamic Azad University, Ahar Branch.2- Academic Member, Islamic Azad University, Ahar Branch.Based on existing theories, geometric models and linear programming, this study has attempted to structurally rehabilitate rural settlements of study region and to discourage settlers from migration at the same time so as to help rural prosperity.Considering the widely extended borders of Iran and the vast number of villages (over 65000) employing extensive service provision strategy-or focused deployment – is neither feasible or economical nor possible, at least in the foreseeable future for all rural households due to its huge financial burdens. Therefore, new methods have to be investigated, for instance, the idea of designating certain villages as Hubs, villages which have capacities and potentials as to retain their population and to cover and serve other villages under their influence. 1- Asistent Professor, Islamic Azad University, Mashhad Branch.The results of the increase a pressure are slope destruction of plants and floods. The conclusion of this research is the necessity of logical and deep understanding of the geomorphological processes in the region. Marand-Jolfa road in its course passes from topographic and geomorphological units. Awareness of the characteristies about these units and knowledge about morphogenes is and active morphodynamic factors and presenting the necessary procedures are the main objectves of this paper. Based on field studies and conclusions from this research, faults, floods, river erosino, slope movements like rockfalls, landslide, debris flows, snow avalanche morphogenes is, stone avalanche, thermoclasty, cryolasty and human morphogenes is, phenomena, are the most important geomorphological factors known along this road, These are the most critical movements of slopes in daradiz valley. In recent years, human activities have changed the morphogenetic landscape in the research area.1- Assistant Professor, Physical Geography Department, Marand Azad Islamic University.
