In contrast, the southern and eastern half of the country is placed on the elevation range of the trough and positive vorticity advection on the axis of the trough derived from the Urals low-height center on the west and southwest of [mathematical expression not reproducible], causing the highest amount of convergence at 850 hPa.
In addition, on the northeast of Africa, Egypt, Syria, Iraq, and Saudi Arabia, a wide area of relatively high pressure of 1022 hPa is observed that in accordance with the low-pressure tongue of the Urals causes positive vorticity advection of [mathematical expression not reproducible] on the west and northwest of Iran.
The high pressure of Europe has created a strong gradient on the Black Sea, Turkey, Iraq, and especially the northern half of the country, and positive vorticity advection of [mathematical expression not reproducible] winds on the country's northwest.
Transfer of moisture from the Mediterranean Sea, the Red Sea, and the Persian Gulf, especially positive vorticity advection of [mathematical expression not reproducible], can be observed on the eastern slopes of the trough.
