At present, the sequence of heavy rains has stopped in Uttarakhand. The people of the state are feeling relieved due to this. However, meteorologists are worried due to the sudden weakening of the monsoon. The reason is that there was almost no rainfall in the last week of August.
According to the Meteorological Department, this trend of monsoon may remain in September as well. In such a situation, premature departure of monsoon cannot be ruled out. Along with this, the overall monsoon rainfall may also be less than normal. However, so far it has been normal.
Monsoon started weakening in the last week of August
This is the first time after the year 2002, when the monsoon weakened in August itself. This time the monsoon arrived in Uttarakhand on June 23 and heavy rains started from the beginning of July itself. This sequence continued for the first three weeks in August as well.
Talking so far, the monsoon season has received nine percent more rainfall than normal. But, August recorded four per cent less rainfall than normal. This happened due to the weakening of the monsoon in the last week of August.
In the last five days, the state has received 70 percent less rainfall than normal. Meteorologists are calling it the effect of El Nino. Exactly the same situation prevailed in the year 2002 as well. Then with the beginning of the second fortnight of August, the sequence of rains started to stop. The monsoon season that year received 28 per cent less rainfall than normal and the monsoon withdrew only in mid-September. Rainfall is likely to be less than normal in September as well.
Generally, the monsoon season in Uttarakhand is considered from June 1 to September 30. Monsoon withdraws at the end of September. Last year, the monsoon had left on October 8. There is no exact forecast for the withdrawal of monsoon this year, but it is expected to leave by the third week of September. According to Bikram Singh, director of the Meteorological Center, rainfall is expected to be less than normal in September as well.
El Nino is responsible for drought
El Nino is also responsible for drought. The El Nino effect is a special meteorological phenomenon that occurs when ocean temperatures are higher than normal in the central and eastern Pacific Ocean. This causes the temperature to rise and warm surface water from the western Pacific begins to move eastward along the equator.
This affects the weather of India. In such a situation, we have to face terrible heat and drought conditions start to develop.
