in this paper, synoptic patterns associated with maximum precipitation over the khorasan region, between 1985-2000 with the computation of some forcing functions are studied and classified into three types. type a: consists of the anticyclones that move from the scandinavian peninsula and central-europe in an east and south-east direction during cold seasons, with relatively high speed and cold...

The emergence of antibiotic-resistant Staphylococcus aureus in particular methicillin-resistant S. aureus (MRSA) is an important concern in burn medical centers either in Iran or worldwide. A total of 128 S. aureus isolates were collected from wound infection of burn patients during June 2013 to June 2014. Multiplex-polymerase chain reaction (MPCR) assay was performed for the characterization o...

introductionmany aspect strongly influence regional climate includes localized surface processes, large-scale patterns, especially mid and upper level tropospheric circulation and many factors control precipitation in the west of iran includes location of emigrate westerly winds systems, jet streams location, humidity flux and topography. upper tropospheric jet stream constitutes a significant ...

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 ...

dust storms are known as hazardous problems in western part of iran. iraq is one of the main sources for dust storm arriving to the western part of iran. the radial basis function network model (rbfn) has been used to assess wind erosion hazards in the source area of dust storms over several western iranian cities. normalized difference salinity index (ndsi) was used to determine the changes in...

Iran, a 4-season land in the world, is located in semi-arid part of Asia. There are several geographical climates in this country, which are the main causes for the existence of diverse ecological conditions. In the north, where the Caspian Sea meets the land, there are three provinces. One of these, Guilan province, (the studied area) is located in the southwest of the Caspian with different g...
