Tropical cyclone movement and surrounding flow relationships.

The relationship between the movement of tropical cyclones and the large-scale circulation which surrounds them was studied. Cyclones were stratified by direction and speed of movement, latitude, intensity change, and size in three ocean basins, the northwest Pacific, the west Atlantic and the Australian-south Pacific region. Twenty-one different stratifications are available in the northwest Pacific, 13 in the west Atlantic, and 6 in the Australian-south Pacific area.-from STAR, 20(20), 1982
