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. [4] In an atmosphere with rich low level moisture and vertical wind shear,[5] narrow, convective rainbands known as squall lines form generally in the cyclone's warm sector, ahead of strong cold fronts associated with extratropical cyclones. Why are the winds in the spiral bands of a hurricane so great? It's been mentioned that Isabel developed some annular qualities. Winds converge beneath these feeder bands, causing air to ascend-ultimately blowing out the tops of these t-storms. Around 74 mph (119 km/h) the strong rotation of air around the cyclone balances inflow to the center, causing air to ascend about 10-20 miles (16-32 km) from the center forming the eyewall.
