Abstract

This paper incorporates remote sensing imagery and image processing techniques to analyze typhoons' evolution into supertyphoons through interactions with cold fronts in the Western Pacific Ocean. The purpose is to enhance understanding and predictability of the tracks and profiles of supertyphoons. Evolutions of typhoons Haiyan (2013) and Hagupit (2014) into supertyphoons were studied. The 3-D profiles of weather systems were reconstructed using multifunctional transport satellite IR cloud images. When interactions between typhoon and cold front happened, enhancements of typhoons were observed causing typhoons Haiyan and Hagupit to strengthen power and evolve into supertyphoons. The origins of typhoons Haiyan and Hagupit are closely located at 152°50E/05°12N and 151°30E/04°19N, respectively. Both typhoons went through The Philippine Sea in the zone of 112°52E-146°11E. The lowest values of central pressures of typhoons Haiyan and Hagupit occurred along their paths at the positions 128°41E/10°16N and 131°06E/11°00N, respectively. Their distances from cold front and average speed of their movement were dominating parameters for the formation of winter supertyphoons. The supertyphoon Haiyan showed higher intensity than the supertyphoon Hagupit. Each of the two typhoons roughly consisted of two paths with the first path moving westerly and the second path northerly. The two typhoons evolved into supertyphoons at the turning points of the two paths. The first paths were about 2330 and 2050 km for typhoons Haiyan and Hagupit, respectively.
