El Nino is a climate phenomenon that occurs when the surface water of the equatorial Pacific Ocean warms abnormally, lasting 8 to 12 months or longer. This phenomenon usually occurs every 3 to 4 years and has a major impact on weather and climate around the world.
This year, due to the influence of El Nino, heat waves have occurred continuously since the beginning of the year, with many places in Son La province recording extreme heat of over 42 degrees Celsius. Due to the influence of severe and especially severe heat, combined with low humidity in the air, there has been and continues to be a high risk of forest fires and droughts. In addition, heat waves can also cause dehydration, exhaustion, and heat stroke to the human body when exposed to high temperatures for a long time. The El Nino phenomenon will continue but its intensity will gradually weaken from now until around June 2024, then tend to gradually shift to a neutral phase in the summer months from June to August with a probability of about 70-80%. It is forecasted that from around September 2024, there is a possibility of transitioning to La Nina with a probability of about 60-75%. Although weakening, the impact of EL Nino always has a lag on temperature and rainfall. The impact of EL Nino mainly causes temperatures to be higher than the average of many years, heat waves are likely to occur more frequently and more severely than the average of many years, appear more frequently and more severely, and there is a possibility of many high temperature records appearing this summer. Along with that, rainfall tends to be less than the average of many years./.
