Spiral rainbands of a hurricane

Spiral rainbands are such a basic structure to a tropical cyclone that in most tropical cyclone basins, use of the satellite-based Dvorak technique is the primary method used to determine a tropical cyclone's maximum sustained winds. See more A rainband is a cloud and precipitation structure associated with an area of rainfall which is significantly elongated. Rainbands can be stratiform or convective, and are generated by differences in temperature. When … See more Rainbands exist in the periphery of tropical cyclones, which point towards the cyclone's center of low pressure. Rainbands within tropical cyclones require ample moisture and a low level pool of cooler air. Bands located 80 kilometres (50 mi) to 150 … See more • weather portal • "Anatomy of a Hurricane".

WebAug 1, 2001 · Spiral rainbands characterize radar and satellite imagery of hurricanes and tropical cyclones. Outward propagating small-scale (10–20 km) bands are detected in recent radar studies (Gall et al. 1998; Reasor et al. 2000). The spiral rainbands are usually … WebSome rainbands move closer to the center, forming a secondary, or outer, eyewall within intense hurricanes. Spiral rainbands are such a basic part of a tropical cyclone that in most tropical cyclone basins, use of the satellite-based Dvorak technique is the main method used to determine a tropical cyclone's maximum sustained winds.
