Spiral rainbands definition

WebThese spiral rainbands were known to be complex structures that possess deep convective cores enmeshed in low altitude precipitative clouds. The eye or core of a tropical cyclone is characterized by low pressure which causes warm air to spiral upward and rise into the atmosphere. A tropical cyclone usually develops a distinct eye when the ... WebJan 3, 2024 · Long bands of rain clouds appear to spiral inward to the eyewall -- these are called spiral rainbands.
