Stakeholders informed of the El-Nino effect in May – Met Chief

Meteorological Department Director General Athula Karunanayake said that through the monsoon discourse, the relevant parties have been informed about the current rain conditions in the country. The Director General who commented further said so many are giving various statements about the dry weather today. The Meteorology Department holds a conference before the start of every monsoon period. People from the fields of Agriculture Department, Irrigation Department, Water Supply and Power are involved in the conference.

The conference was held in May this year as well. The Southwest Monsoon prevails from May to September. Those present at the conference are informed about the upcoming rains. There we clearly said that the south-west part of the country receives the rainfall from the south-west monsoon, but that this time there is a decrease in rainfall in the central mountains. It was also stated that this situation is affected by the El-Nino situation in the Pacific Ocean. The Indian Ocean Dipole was also mentioned and explained.

The other thing is that during the southwest monsoon, rain affects the southwest region. The north and north central farmers get less rain from the southwest monsoon. The people of those areas cannot be blamed for the loss of rain. We expect an increase in rainfall in October, November and December. A decrease in rain is expected from the end of December to April. Anusha Warnasuriya, Director (Climate Change and Research) of the Department of Meteorology who commented on the ongoing El Nino, La Niña, Indian Ocean Dipole –

El-Nino is an abnormally higher than normal sea surface temperature near the Peruvian Islands in the eastern Pacific Ocean. The International Research Institute (IRI) had predicted many months ago that such a situation would occur. La Niña is the opposite of El-Nino. In such a situation, the surface sea temperature near the islands of the Pacific Ocean is cooler than usual. A weak El

Nino condition is prevailing these days. It is believed that this situation will strengthen by December.

For this reason, Sri Lanka is expected to experience more rain in the months of October and November. This is stated by examining the past El-Nino conditions. When there is a strong El Nino condition, we have more rain in October and November. But El-Nino is not the factor that determines our and the world’s weather and climate. There are many other weather phenomena.

Low pressure areas and cyclones have an impact. Indian Ocean Dipole (IOD) also affects the weather and climate of this country. This is where the temperature changes in the west and east of the Indian Ocean. El-Nino occurs in the Pacific Ocean. IOD occurs in the Indian Ocean. Global climate and weather forecasting agencies have said that an IOD situation will occur in the near future.

It is said that the positive situation in the Indian Ocean Dipole may occur in the coming months. When it comes to the positive side, it rains a lot in October and November.

We still have the southwest monsoon. Due to that situation, the rain is less in the hilly areas this time.

This situation is affected by various factors such as the El-Nino situation and the decrease in the amount of water vapor in the atmosphere. If there is a sudden or minor storm in the Pacific Ocean, the Southwest Monsoon may become active for a short period of time. Such situations may occur in August. However, currently, such a situation does not appear.

Like El-Nino conditions, La-Nina conditions have been affecting the world from time to time for a long time. It is currently predicted that the El Niño situation affecting the world this year will end by February or March next year.

Previously, there was an El-Nino situation in 2015 and a La-Nina situation in 2020, 2021, 2022.
