Operational Application of a Tropical Cyclone Recurvature/Non-Recurvature Study Based on 200 MB Wind Fields.

摘要

In his paper, Tropical Cyclone Motion and Surrounding Parameter Relationships, John E. George demonstrates the relationship between various 200 mb wind fields and recurvature/non-recurvature. Evaluation of the wind fields with data independent of George's study indicated that significant modification of his study was required to produce an operationally applicable recurvature/non-recurvature study. Synoptic analysis revealed two distinct environments affecting tropical cyclones, a Winter Regime and a Summer Regime. All tropical cyclones were stratified accordingly. By integrating the results of the evaluation with results from rigorous synoptic and statistical analyses, operationally applicable recurvature/non-recurvature techniques were developed for, both, Winter Regime and the Summer Regime tropical cyclones.
