Information on atmospheric processes that determine weather in concrete region is necessary element of weather conditions monitoring.
The investigation on determining basic types of synoptic situations, which determine veriety of weathher conditions in selected region were carried out in Kazakstan.
The connection with fragments of synoptic process, fixed in surrounded areas (particularly in Mediterranean Sea region), is discovered. The connection between development of separate typical situation in Kazakstan and cyclone regime over the Mediterranean Sea is found out.
Fields of averaged surface air pressure at sea level and geopotential grid surface of 500 hPa (5 x 10) of the north hemisphere were analyzed. These fields characterize development of synoptic situation of separate type.
Time period for this data is 23 years. The results of the analysis show, that type of synoptic situation in the Mediterranean Sea region can be used to forecast duration of the period predominating type of synoptic situation over the Kazakstan region. For example, one of the indications of removal of cyclogenetic area (related to Island's minimum) to east direction and spreading its south part over the Caucasus (This is the reason to appear cyclone on the Mediterranean Sea front over the Black Sea region) is pressure rise in the Central part of the Mediterranean Sea. The same indication is fixed for deep cyclone moving at the north latitudes. Rise and then sharp pressure decrease in the central and east parts of the Mediterranean Sea follow by typical intrusions of cyclone on the Kazak territory from the south-west. Removal of pressure decrease area from the east part of the Mediterranean Sea to the south-east is forerunner for coming cyclones to Kazakstan from the south.
The influence on weather conditions is considered on the base of heat waves in Kazakstan and intensification of wind flooding on the north-east part of the Caspian Sea.
