The ‘610’ cyclone was a typical Jiang-Huai cyclone, and LHR was the main factor in its development (Lv, Zhou, and Chen Citation 2000 ).
WebA circulation system goes through a sequence of stages as it intensifies into a mature tropical cyclone. The storm begins as a tropical disturbance, which typically occurs when loosely organized cumulonimbus clouds in an easterly wave begin to show signs of a weak circulation. Once the wind speed increases to 36 km (23 miles) per hour, the storm is …
