به خواندن ادامه دهیدA tropical cyclone is a rapidly rotating storm that begins over tropical or subtropical oceans, with very violent winds and torrential rain; sometimes accompanied by thunderstorms. A tropical cyclone is a rapidly rotating storm originating over tropical oceans from where it draws the energy to develop.
به خواندن ادامه دهیدThe global accumulated cyclone energy (ACE: an integrated metric of the strength, frequency, and duration of tropical storms) was about 70% of the 1991-2020 average for September. Ten named storms were active in the Atlantic during September, which ties 2010 and 2020 for the most on record.
