This year, monsoon is delayed by a week. Previously it particularly began in Nepal from the first week of June.
According to the Meteorological Forecasting Division’s meteorologist Min Kumar Aryal, atmosphere favourable for the arrival of monsoon is on the gradual process of formation.
The arrival of monsoon requires more influence of Westerly wind than local wind. Monsoon wind originated from the Bay of Bengal should have its presence above six kilometers from the bottom of atmospheric system, but the air has only entered the base so far this year. Currently, the local wind has caused thundershower.
