Premonsoon rainfall like winter in Nepal

Gobinda Prasad Pokharel

This year, Nepal experienced a dry winter. Nepal experienced a dry winter from October 24th, 2022, to February 26th, 2023. Researchers have warned of the rise in wildfires and decrease in productivity due to less rainfall in the winter. With the start of the pre-monsoon, we are experiencing rainfall all over the country.

March, April, and May are the pre-monsoon months in Nepal. At this time, local winds are more active, resulting in precipitation, thunderstorms, and lightning in the evening and afternoon for several hours. The intensity of rainfall is high during the premonsoon, which lasts for only a few hours. If it rains in Bhaktapur, it may or maynot rain in Kathmandu during the premonsoon within a small distance. So, the rainfall is not uniform across the country during the premonsoon.

In the past few days, there has been low and moderate rainfall across the country. The rain has positive impacts for the farmers. The characteristics of the recent rainfall did not match those of the pre-monsoon. It feels like winter rainfall with low and moderate rainfall and cold temperatures.

he total 248 rainfall measurement stations, 113 recorded rainfall. Similarly, on March 19th, 177 stations recorded rainfall, 210 on the 20th March and on September 22, 71 stations recorded rainfall. A maximum of 93.5mm of precipitation was recorded in those stations. Nepal’s average premonsoon precipitation record data (1991–2020) is 226.2mm.

This year’s El Nino has affected the winter rainfall in Nepal. After El Nino ended, Nepal experienced westerlies during the premonsoon. That’s why were are experiencing cold in this march due to this effect and character of rainfall.
