An Evaluation of the WES3 and WES4 Analytic Wind Generation Methods

Abstract

Two methods for generating analytic wind fields for tropical cyclones are evaluated. The two methods utilize the same algorithm for generating the initial wind field. The WES3 method uses a function of the forward speed and the angle between the track direction and surface wind direction to parameterize the wind field asymmetry. The WES4 method applies asymmetry to the analytic wind field using the radius of 35 knot winds provided by a forecast bulletin. Wind fields generated by the two methods are compared and used to force a surge model of Hurricane Ida. Model wind magnitude and direction and water levels are compared for each of the two models and to data.
