Cause of floods in summer

Hossein Ardakani, who is one of the pioneers of Iranian meteorology, pointed to the monsoon phenomenon about the cause of floods in summer and said that this atmospheric phenomenon is directed towards Muscat and Aden, and the moisture of this system, which flows from the Persian Gulf towards Iran, leads to temporary showers. It has been thundering and raining.

According to this expert, Monsoon has entered Iran since Tuesday and moved towards Hormozgan and a part of Fars, and in the coming days, it will cover the center of Iran.

Meteorology has announced that these rains will most likely continue until Sunday, August 9, 1401, and although there will be no rainfall during the day, we should expect heavy but short rains from the evening and early hours of the night. They lead to floods.

Another meteorological expert, Bahlul Alijani, also says that it is the monsoon phenomenon that has led to monsoon rains. According to this meteorologist, these rains, which are called temperate systems, come from Europe and bring the Mediterranean moisture with them and lead to rain. According to Mr. Alijani, the humidity that comes from the Indian Ocean is also very high and the heat of the air causes the intensity of the summer rains to increase and as a result the risk of flooding increases.

Bahlol Alijani said that in Iran, the phenomenon of flooding in summer occurs once every several years and is rare. But the last time Iran faced such a flood was August 1966, which led to a terrible flood.

According to him, high-pressure systems usually pass over Iran in the summer, which do not allow the air to rise, but currently that high-pressure system has retreated and has gone towards Saudi Arabia, and as a result, hot and humid monsoon air has entered Iran and Tehran has also penetrated and led to floods in Iran. This flood also reached Qom, but it is likely that it will not be able to cross Alborz and will stop in this area.

According to experts, the occurrence of these heavy and monsoon rains is normal, but the problem is that due to the drought and the reduction of vegetation in Iran, these rains take the form of floods.

Possibility of flooding in Tehran metro

One of the most important concerns of officials after the flood in Tehran is the possibility of flooding in the subway. In this regard, the head of the Crisis Prevention and Management Organization said:

There were concerns about the possibility of flooding in five metro stations, including Tajrish, Qaim, Navniyad, etc., and it was decided to use sandbags around the entrance of these stations in the next two or three days. It was also built to provide water pumps in these stations as well as some other workshops under construction.

Also, this official has announced that decisions will be made soon to deal with flooding in the metro workshops.

It should be mentioned that as a result of flooding in some areas of Tehran, some parks in Tehran have been closed until now by the decision of the authorities, and the activities of some trade and recreational units on the banks of rivers such as Darband, Derke and Farahzad have also been closed.

Tehran is currently on alert for three days, and as reported by the head of the crisis management prevention organization, Imam highway was supposed to be blocked and Tajrish bazaar was also to be completely closed, but they have refused to implement these decisions at the moment.

This is despite the fact that the flood of Imamzadeh Daoud was not predicted, and as the weather forecasts say, this torrential rain system will threaten Tehran at least until Sunday, August 9.
