Atlantic Niña Forms: A Hurricane Shield?
17 Jul
Summary
- A rare 'Atlantic Niña' climate pattern is forming in the tropics.
- This phenomenon involves cooling sea-surface temperatures in the equatorial Atlantic.
- It may create an atmospheric shield, potentially diminishing the US hurricane season.
A rare 'Atlantic Niña' climate pattern has emerged in the tropical Atlantic Ocean, appearing to form over the past few weeks. This weather phenomenon involves a cooling of sea-surface temperatures in the equatorial Atlantic, which can alter wind and rainfall patterns.
Scientists note that while strong Atlantic Niña events are relatively rare, the current cooling, if it persists, would be one of the weakest on record in over 40 years. Its impact is generally weaker and more localized than the Pacific's La Niña.
Experts suggest that this Atlantic Niña, alongside a powerful El Niño already building in the Pacific, could work together. This combination may create an atmospheric shield, potentially diminishing the intensity and frequency of the United States hurricane season by reducing the heat and moisture vital for tropical storm development.
