Rainfall 29% higher than long-term average

Referring to the rainfall rate in the country during the month of Mordad, he stated that the whole country received rainfall 29 percent above the long-term average.

Increased rainfall in summer does not have much effect on the rainfall rate because the precipitation is low and occurs in limited areas such as the coastal provinces of the Caspian Sea and Sistan-Baluchestan, so it does not change the rate, he concluded.

Since the beginning of the current water year (September 23, 2019), the whole country received 294.5 mm of rainfall, which is 6.7 percent lower compared to the past year, according to the data released on Tuesday by the National Drought Warning and Monitoring Center.
