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]
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.

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 ...
Hurricanes are mixed-phase clouds, meaning that liquid and solid water (ice) are both present in the cloud. Typically, liquid water dominates at altitudes lower than the freezing level and solid water at altitudes where the temperature is colder than -40 °C. Between 0 °C and -40 °C water can exists in both phases simultaneously.
Depending on its location and strength, a tropical cyclone is called a hurricane (/ ˈ h ʌr ɪ k ən,-k eɪ n /), typhoon (/ t aɪ ˈ f uː n /), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean.
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 ...
On shorter time-scales, variability in the maximum potential intensity is commonly linked to sea surface temperature perturbations from the tropical mean, as regions with relatively warm water have thermodynamic states much more capable of sustaining a tropical cyclone than regions with relatively cold water.

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.
