Comparison of Effects of Various Tropical Storms on the Vertical Temperature Structure of the Ocean Using Pictorial Representation.
Abstract
To make comparisons of the effects of tropical storms on the ocean's vertical temperature structure, temperature-depth cross-sections were constructed using bathythermograph data and data from published articles. Upwelling, downwelling and mixing, caused by tropical storms in deep and shallow water, are analyzed and compared. For a slow-moving, intense and very intense tropical storm, upwelling, from a depth of 40 to 65 meters, is observed within the radius of hurricane-force winds. Downwelling as much as 20 meters occurs from 45 to 110 nmi from the path of the storm. This compares favorably with the theoretical results of O'Brien and Reid. A fast-moving, intense tropical storm has a similar effect on the vertical temperature structure if the thermocline is shallow, and upwelling, of a lessor degree than that caused by a slower-moving storm, can occur from a depth of 35 meters within the radius of hurricane-force winds. A very fast-moving, very intense tropical storm can cause upwelling from a depth of 30 meters if the thermocline is shallow. (Author)
