Study of Atmospheric System and its Effect on Flood in Isfahan
Heavy rains are one of the features of arid and semi
arid climates which result in flood. This kind of rainfall originates
from environmental and synoptic conditions. Mediterranean cyclones
are the major factor in heavy rainfall in Iran, but these cyclones do
not happen in some parts of Iran such as Southern and Southeastern
areas. In this study, it has been tried to pinpoint the synoptic reasons
of heavy rainfall in Isfahan through the analysis of the relationship
between this rainfall in Isfahan and atmospheric system over Iran and
the areas around it. The findings of this study show that the major
factor have is the arrival of Sudanese low pressure system in this
region from the southwest, of course if the ascent local conditions
such as heat occur, the heaviest rains happen in Isfahan. In fact this
kind of rainfall in Isfahan has a Sudanese origin and if it is
accompanied by Mediterranean system, heavier rain falls.
