A second type of subtropical cyclone is a mesoscale low originating in or near a frontolyzing zone of horizontal wind shear, also known as a "dying" frontal zone, with radius of maximum sustained winds generally less than 50 kilometers (31 mi). The entire circulation may initially have a diameter of less than 160 kilometers (99 mi).
Weather. A mesocyclone is a meso-gamma mesoscale (or storm scale) region of rotation (vortex), typically around 2 to 6 mi (3.2 to 9.7 km) in diameter, most often noticed on radar within thunderstorms. In the northern hemisphere it is usually located in the right rear flank (back edge with respect to direction of movement) of a supercell, or ...
In meteorology, a cyclone (/ ˈsaɪ.kloʊn /) is a large air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone). [1][2] Cyclones are characterized by inward-spiraling winds that rotate about a ...
The location of the center of a tropical or subtropical cyclone obtained by reconnaissance aircraft penetration, satellite, radar, or synoptic data. [1] Central Dense Overcast. A dense mass of clouds that covers and eyewall or the most tightly curved inner bands of a tropical cyclone.
According to AccuWeather, a "homegrown" or "homebrew" storm is one that forms close to the coast of the U.S. and is most common during the early part of the hurricane season. (The official ...
Mesoscale meteorology is the study of weather systems and processes at scales smaller than synoptic-scale systems but larger than microscale and storm-scale. Horizontal dimensions generally range from around 5 kilometres (3 mi) to several hundred kilometres. Examples of mesoscale weather systems are sea breezes, squall lines, and mesoscale ...
Definition. Mesoscale convective systems are thunderstorm regions which may be round or linear in shape, on the order of 100 kilometres (62 mi) or more across in one direction but smaller than extratropical cyclones, [2] and include systems such as tropical cyclones, squall lines, and mesoscale convective complexes (MCCs), among others.
Cyclogenesis is an umbrella term for at least three different processes, all of which result in the development of some sort of cyclone, and at any size from the microscale to the synoptic scale. Tropical cyclones form due to latent heat driven by significant thunderstorm activity, developing a warm core.
