El Niño's Influence on Hurricane Formation and Impacts
Hurricanes, also known as typhoons or cyclones in different regions, are powerful storms that form near the tropics. The Atlantic hurricane season runs from June 1 to November 30, while the Pacific season spans from May 15 to November 30. These storms require three key conditions to develop: warm ocean water, atmospheric instability, and low wind shear. El Niño, a climate phenomenon characterized by warmer-than-average sea surface temperatures in the Pacific Ocean, can significantly influence hurricane activity. For example, during El Niño years, the increased wind shear in the Atlantic can suppress hurricane formation, while the warmer waters in the Pacific can enhance storm activity there. Historical data, such as the impacts of Hurricane Idalia in 2023 and Hurricane Laura in 2020, highlight the devastating effects of hurricanes, including strong winds, heavy rainfall, storm surges, and coastal flooding.
