The tropical Atlantic has experienced below-average storm activity, attributed to unusually weak lapse rates in the atmosphere, according to reporting from BenNollWeather. The lapse rate, which measures how quickly air cools as it rises, is lower than average. This condition causes rising air to cool faster than its surroundings, inhibiting its ascent and making it more difficult for clouds and storms to develop, as explained by meteorologists. This atmospheric stability may be linked to a warming climate, with potential warming in the tropical upper troposphere causing more stable conditions and fewer storms. This report covers the period from September 9th, 2025, 10:15:40 PM to September 10th, 2025, 1:15:40 AM UTC.
