this research that was made on 66 cyclones in wet periods of midwest of iran in a given period (1973-2003) shows that in intense wet periods, cyclogensis centers of mediterranean sea, sudan, red sea and mesopotamia were severely active and have been very effective in rainfall of study area. such systems in general, with respect to dominant synoptic patterns, enters into study area from three ma...
Introduction Variability is one of inherent properties of the climate system. In addition to the dynamic nature, the climate system is extremely intertwined nature also, so that its components interact with each other and eventually they are changing each other. In general, the climate of a geographic location is controlled by various factors, including Atmospheric Action Centers (AAC...
the areas of the world that have mediterranean style climate are found at about 35 degrees north and south of the equator, on the western sides of continents. the distinctive feature of this climate is the small amount of rain in the summer. overall, the climate has a moderate amount of rainfall and warm winters and hot summers and. the climate of the mediterranean region is conditioned by its ...
Climate control centers in each area are diverse and understanding how they relate to the atmospheric components of the Earth's surface contribute to prediction of climate fluctuations. In this study, by using Pearson's correlation and multivariate regression in a thirty-year period (1961-2010), the relationship between widespread rainfall anomalies in entire of Iran west with temperature a...
a major concern in the last few years has been the fact that the cultural centers are keeping distance with what they have been established for and instead of reproducing the hegemony, they have turned into a place for resistance and reproduction of resistance against hegemony. because the cultural centers, as urban public spaces in the last two decades, have been the subject of ideological dis...
Abstract A key issue in conservation biology is recognizing and bridging the gap between scientific results and specific action. We examine sea turtles—charismatic yet endangered flagship species—in the Mediterranean, a sea with historically high levels of exploitation and 22 coastal nations. We take sea turtle rescue facilities as a visible measure for implemented conservation action. Our stud...
the mediterranean is one of the most important cyclogenesis regions in the northern hemisphere. the depressions occurring in specific areas of the mediterranean region and cyclonic tracks have been the subject of extensive climatological research. the climate of the mediterranean region is conditioned by its position in the transition area between the sub-tropical high pressure belt and the mid...
Cyclones as the most important factor in the turbulence of mid-latitude regions are low pressure centers that have one or more closed Isobaric curves. Mid-latitude cyclones are responsible for transfer of the heat and moisture between the tropics and the polar regions. Mediterranean cyclones have the most important role in Iran's rainfalls and get from different tracks to the country and affect...
the caspian sea contains great resources of oil and gas. the caspian sea is a 700- mile- long body of water in central asia, land located between azerbaijan, iran, kazakhstan, russia and turkmenistan. iran was challenges and opportunities in the caspian region. key question in this thesis includes three section that first question, opportunities of iran in the caspian region, second question ch...
the present study aimed to investigate representation of discourse markers and metadiscourse markers in conversations and readings of general elt coursebook series used in the language centers of iran. to this aim, four elt coursebooks popularly taught in language centers of this country were analyzed based on fung and carter’s (2007) framework regarding discourse markers and hyland’s (2005) fr...
