Environment Focus : Impact of La-Nina and El Nino on global weather and its effects on the Indian Monsoon system

Edited by Megha Chaubey

El Niño is the term for the warm-up phase of the El Niño Southern Oscillation (ENSO), a global climate pattern that influences global warming and rainfall. Warming in the central Pacific Ocean east. During an El Niño event, sea temperatures across the Pacific can warm by 1–3 ° F or higher for anything between a few months to two years.Sea temperatures play a major role in global climate change, which contributes to two of the worst phases of the natural cycles. I.e., El Nino / Southern Oscillation and La Nina. Both of these terms refer to the dramatic change in the temperature of the oceans across the tropical Pacific and to the strongest force on Earth. To raise awareness. Sea temperatures play a major role in global climate change, which contributes to two of the worst phases of the natural cycles. I.e., El Nino / Southern Oscillation and La Nina. Both of these terms refer to the dramatic change in the temperature of the oceans across the tropical Pacific and to the strongest force on Earth.

The impact of El Nino and La Nina on the Indian climate

1. El Nino in winter causes warmer climates over the Indian subcontinent and in summer, leading to drier conditions and less rainfall. Although La Nina results in better than normal monsoon in India.

2. India experienced a severe rainfall during the El Nino years of 2002 and 2009 while heavy rainfall was common during the El Nino years of 1994 and 1997. It means that about 50 percent of the year with El Nino in the summer, India experienced a drought during the monsoon season.

3. Crops such as Paddy, Maize, Groundnut, Guar, Castor, Tur, Moong and Bajra will suffer as a result of El Nino.

The impact of El Nino and La Nina on Global Weather

El Nino and La Nina have a huge impact. El Nina resulted in a rising tide of warmth over the earth and a cool breeze that carried moisture from the sea, bringing heavy rains or droughts to the area. La Nina often results in better than the normal monsoon in India. But apart from these two, there are other factors that affect the Indian rain pattern such as the North Atlantic SST, Equatorial SE Indian Ocean SST, East Asia Mean Sea Level Pressure, North Atlantic Mean Sea Level Pressure and North Central Pacific atmosphere.

Although El Niño and La Niña have an impact on global climate patterns; however, they do not affect all regions or their effects are not the same in one area. In many places, especially in the tropics, La Niña (or colder episodes) produces almost every kind of El Niño climate change. For example, parts of Australia and Indonesia are often dry during El Niño but are generally wetter than normal during La Niña. For more accurate information at national or local level, it is important to consult the National Meteorological and Hydrological Services. The WMO Regional Climate Centers may also provide specific information at national and regional levels.

The effects of each La Niña event are quite different. They depend on the intensity of the event, the time of year in which it grows and the interaction with other climatic conditions. La Niña is often associated with wet conditions in eastern Australia, as well as heavy rainfall in Indonesia, the Philippines, and Thailand. La Niña often leads to increased rainfall in northeastern Brazil, Colombia and other northern parts of South America and is associated with a lack of rainfall in Uruguay and parts of Argentina. Dryer conditions are more common along the coast of Ecuador and in North and West Peru.

La Niña episodes include wave-like jet flows over the United States and Canada in the northern winters, colder and more stormy than the central North, and warmer and milder conditions in the South. La Niña events are often associated with rising rainfall in southern Africa, though they are not the only factors involved. La Niña is associated with a drought in eastern Africa – for example in Somalia and eastern Kenya.It is important to emphasize that factors such as the Indian Ocean Dipole, the North Atlantic Oscillation / Arctic Oscillation can also have a significant impact on seasonal climate.
