Investigation of blocking trend in Siberian and Azores high pressure systems in the meteorology of the Iranian plateau

Barley is a fluid that any imbalance in any part of it leads to the movement and movement of matter to eliminate the imbalance and to create a balance in the atmosphere. Daily observations show constant and constant flux of molecules (matter) in the direction The balance of forces is shown. If air is at a disruption point, a new flow of matter and energy will immediately take place. Otherwise, a sharp difference in the distribution of heat and humidity will occur on the surface of the earth. Such a thing in the atmosphere of possibility Not acceptable. Tahua's role is the ability to rotate around an axis. The relative tachypipes are the size of the fluid spin around the pivot perpendicular to the ground. Therefore, the fluid that traverses the curve path is tangent, provided that its radial configuration does not eliminate its tangential velocity. This is called a tangent to a relative curvature. Barotropic atmosphere is atmospheric, the density depends only on the pressure, so the isobaric levels are surfaces that have a constant density. For ideal gases, if the atmosphere is barotropic, the isobaric levels will be the same isothermal levels. It can be claimed that the geostrophic in a barotropic atmosphere independent of altitude it works . Therefore, barotropy creates a very intense position in fluid motion. On the contrary, when the vertical distribution of pressure and temperature does not coincide, or on the map of the atmosphere, the curves of the same height are converted to homogeneous lines, and they say that the atmosphere is a bucolic or baroclinic In this case, the winds cut off the coherent curves, either the height or the thickness, and in the atmosphere where both the temperature and the density depend on the density and the baroclinic atmosphere. In baroque clay, the geostrophic wind is generally upright, and this The ordering depends on the horizontal gradient of the temperature (depending on the thermal wind formula). Baroquinck in the dynamics of meteorology It is very important. In the eastern half of the North Atlantic Ocean, a cool atmosphere with a cold spill on the north-east of Iran and Turkmenistan is witnessing the warmth of the Kusi branch. In this study, the standard precipitation data (SPI) of ۲۰۱۴-۲۰۱۴ were extracted from drought and wetland of the region. ۱۹۹۹ was selected as the driest year and ۱۹۸۲ as an example. The synoptic maps in ۴ levels of sea level pressure, hectoscopic meters in the months of January February, March, April, November and December, at the altitudes of ۱۰۰۰, ۸۵۰, ۷۰۰, and ۵۰۰ geopotential meters were determined and analyzed. The central Farband closed closed in ۱۲ months of the ۱۹۹۹ rainfall, at different levels, on a monthly basis at various levels, was closed at a level of ۵۰۰ HPA at ۰.۹۸ Hectopascus. Thus, in ۱۹۹۹, it was more severe than dry year, and ۱۹۸۲ has the most prolonged period of this ۴۰-year period (۲۰۱۴-۲۰۱۴) and has closed more percentage of the center of the wheel. Other results indicate that the axis was drooping in arid areas in the East and West in ۱۹۹۹ and ۱۹۸۲. This situation is more visible in the combination of Siberian and Azores high tides and the Tibetan plateau
