Do the high pressure and low pressure areas around the Iranian plateau have an effect on the climate of Iran and the climate of the Iranian plateau?
As you know, there are many high-pressure and low-pressure areas around the Iranian plateau, and this has made it effective in different seasons throughout history. For example, in the summer season, when the heat of southern regions such as Saudi Arabia, which is a low-altitude plateau and a high-pressure area, creates a sinusoidal current in the upper blocking mode or omega to the north and causes heat transfer from the Giza region of Saudi Arabia, which is a dynamic warm region. will be . Tropics of Cancer where the sun is in and around the tropics. The sun shines vertically in the summer season, when it also shines in the Tropic of Cancer, it emits a sinusoidal transmission to the north, i.e. the north of the Iranian plateau, and causes the region to heat up, but that is not the whole story. . heat; It also brings moisture from the Indian Ocean. which sometimes causes heavy rains and floods in the summer season. As in 1366 in Tehran and Qom, GNU rains caused torrential rains.
2- In the winter, the Siberian plateau, the Tibetan and Pamir plateau, and the Mongolian plateau are located in the northeast of the Iranian plateau, because in the winter, the polar air flows in a sinusoidal fashion from the west to the north. It merges with the polar pressure with the dynamic high pressure of Siberia and the Tibetan Plateau and becomes a pressure curve and appears as Omega and Rex Blocking Rex or Blocking Omega and the entire region of the Iranian Plateau is covered, and the duration of each block in 15 days It lasts for 15 days, and because this blocking lasts longer, it only brings cold and prevents the humidity of the Mediterranean Sea, which is low pressure. They merge with polar high pressure and become very powerful, forming the powerful Siberian Blocker, which gives rise to Omega and Block Rex. It comes from the Mediterranean low pressure system to fight. A Mediterranean system and even a monsoon or monsoon system from the southern Indian Ocean can stop it and make it cold and dry like this year's drought in Iran. But sometimes the low pressure of the Mediterranean, the Black Sea and the Caspian Sea takes its moisture to the northwest of the cloud plateau and it falls as snow. For this reason, it always snows more in the northwest of Iran's plateau.
3- In spring and autumn, the conditions are different because other high pressure and low pressure systems play a role, for example, in spring we see from the Atlantic Ocean that the atmospheric river system is formed from west to east and blows, and in the north of the equatorial region and the region Azores. This flow depends on the Scandinavian blocking system in northern Europe. If the Scandinavian low pressure system is strong, i.e. creating a low search and blocking the double loop, the AO precipitation system becomes positive, causing heavy rain and flooding in Europe. And since Europe is a plain, it rains a lot in Northern Europe, so remember it rained a lot in Germany last year. But if the Scandinavian low pressure system is weak. The AO precipitation system becomes negative and rises higher, so the river system allows a sinusoidal current to flow from west to east and into the Middle East, either in spring or fall, Atlantic moisture from the west, Mediterranean moisture to the brings to the east. And in the south of Iranian plateau and southwest of Iran, like two years ago, in Khuzestan and Lorestan province in Poldkhtarsil city, we witnessed torrential rain.
