Feeder Bands In tropical parlance, the lines or bands of thunderstorms that spiral into and around the center of a tropical system. Winds converge beneath these feeder bands, causing air to ascend-ultimately blowing out the tops of these t-storms. However, the hurricane's destructive winds and rains cover a wide swath. There are sometimes gaps in between spiral rain bands where no rain or wind is found. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Strong upper level winds destroy the storms structure by displacing the warm temperatures above the eye and limiting the vertical accent of air parcels.

I get the impression that hurricanes with large eye diameters are more likely to loose at least 1 or 2 categories of intensity before making landfall. We are starting to get feeder bands from Hurricane Irma here in South Florida. The conservation of angular momentum means is objects will spin faster as they move toward the center of circulation. However, as the speed increases, an outward-directed force, called the centrifugal force, occurs because the wind's momentum wants to carry the wind in a straight line.

Winds converge beneath these feeder bands, causing air to ascend-ultimately blowing out the tops of these t-storms. When used to imply only upward vertical motion, it is then the opposite of subsidence. Conversely, the farther the hands are from the body the slower they spin.
