El Niño likely to bring extreme weather across world: WMO

Recently the World Meteorological Organization (WMO) has said that the world should be prepared for El-Nino.

According to WMO, the active La-Nina effect for three years has now ended and the tropical Pacific region is currently in ENSO-neutral condition. This means that this situation clearly indicates the presence of neither El-Nino nor La-Nina.

El Nino is a naturally occurring climate pattern. It is related to warming sea surface temperatures in the central and eastern tropical Pacific Ocean.

In contrast, the region cools down during La-Nina. Also, both La Niña and El Niño are the cold (La Niña) and warm (El Niño) phases of the El Niño Southern Oscillation (ENSO), respectively.

At present, the probability of occurrence of El-Nino is high. Also the WMO has highlighted the fact that the Spring Predictability Barrier (SPB) over the Northern Hemisphere has not yet been deactivated. ,

SPB is a phenomenon related to weather and climate forecasting. In this, the accuracy of the forecast decreases during the onset of spring.

Effect of El Nino on India

  • Pressure on Agriculture Below average rainfall affects agricultural productivity.
  • Food Inflation: Lower production will increase the demand for food grains.
  • Increase in power consumption: As the temperature is higher than normal, there will be an increase in power consumption.
  • Increase in power consumption: As the temperature is higher than normal, there will be an increase in power consumption.
  • Power generation: Less rainfall will have a negative impact on the generation capacity of hydropower plants.

Policy measures:

  • क्षेत्र-विशिष्ट शमन योजनाएँ,
  • आवश्यक खाद्य पदार्थों का बफर स्टॉक,
  • सूखा सहने में सक्षम फसलों की किस्मों का उत्पादन आदि।
  • Area-specific mitigation plans,
  • Buffer stock of essential food items,
  • Production of varieties of crops capable of withstanding drought, etc.
