Tropical Cyclone's Key Motion Concepts *
Tropical Cyclone motion results from a variety of causes:
Environmental Steering - To a first approximation, Tropical Cyclones (TC's) go where the winds of the large-scale environment blow them (i.e., TC's are a "cork in the stream").
Tropical Cyclone Propagation - The motion of TC's usually departs in a minor, but not insignificant way from the steering provided by the large scale environment.
Tropical Cyclone Environment Interaction - In certain situations, the circulation of the TC interacts with the environment in such a way as to significantly alter the structure of the environment, thus modifying the environmental steering winds which are a primary source of TC motion.
