A Preliminary Analysis of Mesoscale Effects of Topography on Tropical Cyclone-Associated Surface Winds.

Abstract

An analysis is made of the influence of topography on tropical cyclone-associated strong surface wind conditions for Subic Bay, Republic of the Philippines, by means of an environmental wind tunnel. Surface flow patterns were deduced by smoke and surface oil films, while isotach and gust values were obtained by hot wire anemometers. Laboratory results show the significant effects of the mountainous regions surrounding the Subic Bay habor complex and indicate preferred shelter locations. These results are compared with synoptic observations and a high-resolution (0.19 n mi) diagnostic, one-level, primitive equation model. Where direct comparisons can be made, all techniques appear to show qualitative agreement. (Author)
