Atlantic hurricane [SEP] Steering factors
Tropical cyclones are steered by the surrounding flow throughout the depth of the troposphere (the atmosphere from the surface to about eight miles (12 km) high). Neil Frank, former director of the United States National Hurricane Center, used the analogies such as "a leaf carried along in a stream" or a "brick moving through a river of air" to describe the way atmospheric flow affects the path of a hurricane across the ocean. Specifically, air flow around high pressure systems and toward low pressure areas influences hurricane tracks. In the tropical latitudes, tropical storms and hurricanes generally move westward with a slight tendency toward the north, under the influence of the "subtropical ridge", a high pressure system that usually extends east–west across the subtropics.
