Is there a drought or drought in Iran this year?
As you know, through statistical climatology and according to the statistical methods and forecasting of the synoptic states of the atmosphere in the region, it is possible through the time series of meteorological data and checking the temperature and precipitation in a meteorological station and its downward and upward trends. During 20 to 50 years, he predicted the past, present and future through climatology software. Based on the fact that I wrote my book under the title "Blocking Time Series in Iran Plateau", I have stated that during the process of meteorological data and meteorological sites that show the circulation maps of blocking through Gordes maps, it can be said: According to the graphs on page 18 to 21 of the book, there are graphs from 2016 to 2058, and the graph shows the breakdown of the time series of rainfall at Mashhad station, and because blocking in Iran is of Omega or Rex type and its hours It is about 4000 kilometers long and covers the entire plateau of Iran. So we conclude that this year the amount of precipitation in the eastern areas where most of the blocking prevails will reach up to 200 mm and in the western part of Iran where the blocking wave reaches and less maybe it will reach about 250-300 mm and because of the rotation factor It is mentioned and the high pressure areas are integrated from the side of Sibarb and the Tibetan Plateau and towards the northeast of these blockings which create a dry or cold and icy hole in the winter season and because it has a dynamic state, it is more cold and dry and in the omega state. This blocking is formed. So, according to this process, this year, in 2023 and 2024, the process of drought prevails, and this downward trend prevails in Iran, and we have this downward trend in the upward direction until 2025, and in the years 2025, 2026, 2027, and 2028, there will be rain due to That the blocking pressure is removed from Iran a little and the conditions of the atmospheric river in Iran are the same as in the past few years, when the low-level Scandinavian blocking system is weak and the AO is positive, the Atlantic precipitation system rains over Europe, and the atmospheric surface rains over Europe. But when the Scandinavian blocking system is strong and the AO is negative, it means that the Scandinavian blocking has formed to the bottom of the omega state, and the atmospheric surface that is from the Atlantic Ocean above the Azores region in the north of the equatorial region is moving towards the east with its sinusoidal state. And according to the synoptic maps in Hepto Pascal levels in Gardes or NOAA maps, it shows that, for example, 2 years ago in the Khuzestan region of Iran, especially Pul Dokhtar, heavy rains and floods fell. which shows that there is a coordination between the atmospheric river in the west of Iran and the Siberian blogging in the northeast of Iran, and there is a close connection in terms of synoptic and drought activity in Iran.
