El Niño:
- During El Niño, the Pacific Ocean experiences warmer-than-usual sea surface temperatures in the central and eastern Pacific Ocean. These warmer waters tend to enhance vertical wind shear over the Atlantic Ocean.
- Increased wind shear can disrupt the formation and organization of tropical storms and hurricanes because wind shear can tear apart developing storm systems.
- As a result, El Niño tends to lead to less hurricane activity in the Atlantic basin compared to average years.
La Niña:
- During La Niña, the opposite happens. The Pacific Ocean experiences cooler-than-usual sea surface temperatures in the central and eastern Pacific.
- These cooler waters in the Pacific tend to weaken the vertical wind shear over the Atlantic Ocean.
- With reduced wind shear, the conditions become more favorable for tropical storm and hurricane development and intensification in the Atlantic.
- As a result, La Niña is typically associated with more active hurricane seasons in the Atlantic basin.
It's important to note that El Niño and La Niña are not the sole factors that influence hurricane activity. Other factors, such as the state of the Atlantic Ocean itself (such as sea surface temperatures and atmospheric conditions) and the overall climate patterns, also play significant roles in determining the characteristics of each hurricane season.
As for next year's hurricane season, it's too early to make precise predictions. However, long-range forecasts often consider factors such as El Niño/La Niña patterns and other climate indicators to make estimates about the potential activity for the upcoming season.
The National Oceanic and Atmospheric Administration (NOAA) typically issues its seasonal hurricane outlook around May each year, providing an indication of the predicted activity for the upcoming Atlantic hurricane season. These outlooks consider various factors, including El Niño/La Niña conditions and other climate models, to provide a general idea of what the season might bring.
As more information and data become available closer to the hurricane season, forecast models can be further refined to provide more accurate outlooks for specific regions.
