The first working group report of the IPCC Sixth Assessment Report – published in 2021 – assessed that the global occurrence of rapid intensification likely increased over the preceding four decades (during the period of reliable satellite data), with "medium confidence" in this change exceeding the effect of natural climate variability and thus stemming from anthropogenic climate change.
They report that in their simulation the seeded hurricane initially weakened the surface winds in the region of seeding. The eye of the hurricane eventually contracted and became stronger, but the average of the total wind field was weaker. In this best case scenario, they report that seeding reduced the hurricane-force winds by 25%. [5]
A study of 2020's storms of at least tropical storm-strength concluded that human-induced climate change increased extreme 3-hourly storm rainfall rates by 10%, and extreme 3-day accumulated rainfall amounts by 5%, and for hurricane-strength storms the figures increased to 11% and 8%. [35]
The 2024 Atlantic hurricane season has come to an end, and it brought a number of particularly damaging storms. Climate change is not thought to increase the number of hurricanes, typhoons and ...
A storm's strength is defined by its sustained wind speeds, with a Category 1 hurricane carrying wind speeds of 74-95 mph (119-153 kph), while a dangerous Category 5 storm has wind speeds of 157 ...
Depth of 26 °C isotherm on October 1, 2006. There are six main requirements for tropical cyclogenesis: sufficiently warm sea surface temperatures, atmospheric instability, high humidity in the lower to middle levels of the troposphere, enough Coriolis force to sustain a low-pressure center, a preexisting low-level focus or disturbance, and low vertical wind shear.

Hurricane Mitch 3D Satellite on Oct. 26, 1998. The Atlantic hurricane season officially began on June 1, and with the season underway, the potential for devastating storms could occur at any time.
An average value for the RMW of 47 kilometers (29 mi) was calculated as the mean (or average) of all hurricanes with a lowest central atmospheric pressure between a pressure of 909 hectopascals (26.8 inHg) and 993 hectopascals (29.3 inHg). [6] As tropical cyclones intensify, maximum sustained winds increase as the RMW decreases. [7]
