The World Meteorological Organisation (WMO) has issued a warning that an El Nino event is likely to develop as early as May-July 2023, potentially exacerbating adverse weather conditions in South Asia, including India. This development could impact global temperature and rainfall patterns.
Revised Timeline for El Nino
Earlier predictions had suggested that El Nino conditions would emerge in the second half of the monsoon season, around August-September. However, the latest assessment from the WMO indicates an earlier onset, raising concerns for the Indian subcontinent.
Characteristics of El Nino
El Nino events typically occur every two to seven years and last for about nine to twelve months. They are known to disrupt temperature and precipitation patterns across different regions, often leading to a warming effect on the global climate. The phenomenon is associated with the warming of sea surface temperatures in the central and eastern Pacific Ocean.
Impact on Indian Monsoon
Amid the growing risk of an El Nino event, the India Meteorological Department (IMD) has already predicted below-normal monsoon rainfall for India this year. A weak monsoon could have significant implications for agriculture, water resources, and the overall economy, as a large part of India's population depends on rain-fed farming.
Global Implications
Beyond India, El Nino can cause extreme weather events worldwide, including droughts in some regions and floods in others. The WMO continues to monitor the situation closely and urges governments to prepare for potential climate-related disruptions.
