A growing array of tools to measure conditions inside one of nature's most fearsome storms saw quite a workout in the 11 hurricanes, including five landfalling hurricanes, so far this hurricane ...
Hurricane Ian was a prolific lightning producer as it strengthened into a Category 5 hurricane on its approach to Florida. Storm chasers along the coast of Florida even witnessed cloud-to-ground ...
This project set out to seed clouds outside the eyewall, causing a new eyewall to form and weakening the storm. When it was discovered that this was a natural process due to hurricane dynamics, the project was quickly abandoned. [8] Research shows that 53 percent of intense hurricanes undergo at least one of these cycles during its existence. [15]
Tropical cyclones form as a result of significant convective activity, and are warm core. [11] Mesocyclones form as warm core cyclones over land, and can lead to tornado formation. [13] Waterspouts can also form from mesocyclones, but more often develop from environments of high instability and low vertical wind shear. [14]
Annular hurricanes have been simulated that have gone through the life cycle of an eyewall replacement. The simulations show that the major rainbands will grow such that the arms will overlap, and then it spirals into itself to form a concentric eyewall. The inner eyewall dissipates, leaving a hurricane with a singular large eye with no rainbands.
A Hurricane Hunters engineer captured video from inside Hurricane Helene's eye Wednesday after it formed along the Gulf of Mexico.
A mesovortex is a small-scale rotational feature found in a convective storm, such as a quasi-linear convective system (QLCS, i.e. squall line), a supercell, or the eyewall of a tropical cyclone. [ 1 ] [ 2 ] Mesovortices range in diameter from tens of miles to a mile or less [ 3 ] and can be immensely intense.
A simultaneous hurricane watch and tropical storm warning means tropical storm with sustained winds of 39 to 73 mph will likely hit your area within 48 hours. However, it also means the weather ...
