RELATION OF CHANGES IN STORM TIDES ON THE COAST OF THE GULF OF MEXICO TO THE CENTER AND MOVEMENT OF HURRICANES

Abstract

Abstract SYNOPSIS A brief summary of what is known bearing directly on this subject concerning wind and waves is given. Hurricanes are in all instances preceded by storm tides. The water commences rising on the coast in front of the cyclonic area, one to two days before the storm in experienced. The wind velocities and directions in different parts of the hurricane, as deduced theoretically, do not meet the requirements in this study to explain the rises in tides. Composite charts showing the actual wind directions and velocities determined from stations in the different parts of the cyclonic area are submitted. In the right-hand rear quadrant the winds blow with much greater velocity and persist in the same direction longer than in any other part of the hurricane. At stations in this quadrant the wind has been found to blow for 24 hours or longer with a direction in line with the advance of the hurricane, with an average velocity of 60 miles per hour, and for 13 hours at 70 to 85 miles per hour.
