June 10, Kathmandu : Monsoon particularly begins in Nepal from the first week of June. But this time, it has not appeared till June 10.
According to the Meteorological Forecasting Division’s meteorologist Min Kumar Aryal, atmosphere favorable for the arrival of monsoon is on the gradual process of formation. More influence of Westerly wind than local wind is required for the arrival of monsoon. Monsoon wind originated from the Bay of Bengal should have its presence above six kilometers from the bottom of the atmospheric system, but the air has only entered the base so far this year.
The present thundershower in morning, evening and night is triggered by the local wind.
