May 17, Kathmandu. In the districts of Terai Madhesh, people’s life has been affected due to rising heat. The temperature has reached more than 40 degrees Celsius in Terai districts. Due to the hot sun and hot wind, it is impossible to leave the house in the afternoon. Therefore, those who live by wage labor are the most affected by the heat. Schools have been closed in some districts.
Since there are still two weeks left for the Sardar date for monsoon to enter Nepal, there is a possibility that we will have to face the heat for a few days. The earliest date for monsoon to enter Nepal is June 13. But sometimes the monsoon sets in before and after the Sardar date.
When will monsoon enter Nepal this year? Meteorologists say that it is not possible to answer this question yet. Because Nepal’s Department of Water and Meteorology does not have the technology and manpower to forecast long-term weather.
Monsoon enters Nepal from South Indian Ocean in Nepal, Kerala in India, Bay of Bengal, Sikkim from Taplejung-Ilam in Nepal. In a statement issued by the Indian Meteorological Department on Wednesday, it is mentioned that the environment is suitable for monsoon to enter till Thursday (today). But till the time of preparing this news, monsoon has not entered in India. In India, the monsoon first enters Kerala and gradually spreads across the country.
Monsoon usually arrives in Nepal within a week to ten days after the arrival of monsoon in India. But it cannot be said that this situation always happens.
According to senior meteorologist Varun Paudel, various parameters are looked at to announce the onset of monsoon. “Generally speaking, for the monsoon to enter Nepal, the influence of the western wind prevailing in Nepal should be replaced by the eastern wind,” says senior meteorologist Paudel, “Apart from that, the anti-cyclone (Tibetan High) should move a little higher (to the north), what is the condition of the upper atmosphere of Nepal, and by looking at many technical things, the monsoon A conclusion is drawn as to whether it has been entered or not.’
A few days ago, there was rain in Nepal due to the partial effect of the cyclone developed in the Bay of Bengal. Named Ramel, the cyclone had a major impact on the eastern and central parts of Nepal. Now its effect has been removed from Nepal, so the heat has increased excessively.
Does the cyclone have any effect on the arrival of monsoon? Meteorologists say that the cyclone will not play a role in the onset of monsoon sooner or later. But the presence of cyclones can make the monsoon more active or dry.
Senior meteorologist Varun Paudel says, ‘If the cyclone is towards the northeast direction of Nepal, it can make the monsoon somewhat active. But if it is towards the Bay of Bengal, it can make it even drier. Because the cyclone pulls the water vapor towards itself and the water vapor coming towards us also moves there. Depending on where and in which direction the cyclone is going, it depends on whether the monsoon will be active or inactive.’
With the impact of global climate change, both the arrival and departure of monsoon in Nepal have been delayed for the past few years. Looking at the details of the last decade, it seems that the monsoon has left Nepal only after October 2.
Last year, the monsoon entered on 14th June (31st June) and left on 15th October (28th October), one day later than the Sardar date of 13th June. During this period, the annual rainfall is up to 80 percent. During this year’s monsoon period (from June to September), most places in Nepal are expected to receive more than normal rainfall.
But it is not yet possible to say when the monsoon will enter Nepal this year. Vibhuti Pokharel, information officer of the Department of Water and Meteorology, says, ‘Sometimes even after arriving in India, it stops midway and enters Nepal late, so it is not possible to say the probable date of monsoon arrival in Nepal.’
Tribhuvan University Meteorology Department Associate Professor Dr. According to Vinod Pokharel, the recent cyclone Remal is likely to make a difference in the arrival of monsoon. Looking at the current progress, the monsoon should enter before June 10. However, this cannot be said as Cyclone Remal has affected some things’, he said.
