The US National Oceanic and Atmospheric Administration (NOAA) has issued a forecast suggesting a significant El Nino event for the Northern Hemisphere from March to May 2024, with a 1 in 3 chance of it becoming a “historically strong” Super El Nino. This weather phenomenon has far-reaching impacts on global weather patterns and can affect various aspects of life.
What Is El Nino?
El Nino is characterized by the warming of waters in the Pacific Ocean near South America. It plays a pivotal role in influencing extreme weather events worldwide, with significant implications for food production, water availability, and the overall well-being of people and ecosystems.
Chances of a Strong El Nino in 2024
The likelihood of a strong El Nino occurring in 2024 is estimated to be between 75% and 80%. This means that equatorial sea surface temperatures will be at least 1.5°C warmer than the long-term average. There’s also a 30% chance that temperatures could exceed 2°C, leading to a “historically strong” event, similar to occurrences in 1997-98 and 2015-16. During these years, extreme temperatures, droughts, and floods wreaked havoc globally.
Impact of El Nino in Different Regions
- North America: In North America, a strong El Nino typically brings drier and warmer conditions. Southern parts of the United States usually experience wetter weather and slightly cooler temperatures in the winter.
- India: El Nino’s influence in India is often associated with weakening monsoon winds and dry weather, resulting in reduced rainfall during the monsoon season. Super El Nino events can disrupt typical weather patterns, leading to unusual and sometimes extreme weather events. This may include heavy rainfall and flooding in some regions and extended dry spells in others. Notably, southern India tends to be less affected compared to the northern regions.
Historical Monsoon Impact
Throughout history, approximately half of the El Nino years have caused drought conditions during the monsoon season in India, with all-India rainfall falling below 90% of the long-term average. These variations are closely tied to oceanic and atmospheric conditions, and the NOAA plans to provide updated predictions in November based on the latest data.
It’s important to monitor these predictions as they can significantly impact various aspects of life, from agriculture to water resources and overall weather patterns.
Stay Informed for Potential Changes
As the NOAA continues to gather data, it’s crucial to stay informed about any updates regarding the El Nino forecast for 2024. This information will play a vital role in preparing for and mitigating the potential impacts on regions across the Northern Hemisphere, especially in India, where monsoons are a lifeline for agriculture and water supply.
