Synoptic evaluation heavy precipitation Khorasan Razavi Province March 29, 2007

In order to explain the fundamental interaction of the atmosphere and surface environment and the discovery of the circulation patterns cause heavy precipitation in Khorasan Razavi 29/03/2007 AD precipitation index was chosen as one day. Output of cell-based database for data loss is the main focus of the day Aphrodite Dargaz East was estimated at 43.66 mm. In order to determine of the front synoptic patterns forming, functions: moisture flux, volubility, maps, ground level pressure and levels of 500, 700 and 850 for 6 hours H.p NCEP/NCAR base obtained were analyzed with environmental approach to circulating. The results showed that the pattern of occurrence heavy precipitation trough atmosphere when it landed deep in the Mediterranean axis in the East Mediterranean and the Red Sea also serves as the main source of precipitations. During the occurrence of such circumstances, a barrier system will be deployed on the northern Iran South branch system to the west of the Arabian Sea and the Persian Gulf to the western regions of the country to be drawn. Under these conditions the moisture in areas of Sudan and the Red Sea is high and how the wind is such that moisture is sucked from the Red Sea and Arab and western parts of Iran guides. The initial formation of the mentioned systems in the West - East, but after entering Iran will shift its path towards the North East. Mentioned is a confirmation of the mechanism of satellite imagery as well.
The general direction of the two mentioned systems formed at the beginning of the West - East, but after entering Iran will change their route to the North East. Satellite images, as well as confirmation of the mechanism are mentioned.
