Rainfall Variations Due to Twin Typhoons over Northwest Pacific Ocean

摘要

This paper focuses on the investigation of therainfall variations due to twin typhoons Saola and Damrey occurred in 2012 over Northwest Pacific Ocean (NPO). Genesisand landfall of the two typhoons are on the same day, however the track andrainfall area are different. We have chosen the Global PrecipitationClimatology Project (GPCP) and Tropical Rainfall Measuring Mission (TRMM) datafor this analysis. The results are illustrating as follows: typhoon Saolaproduced higher rainfall than typhoon Damery. The rainfall pattern of typhoonSaola having sufficient affect typhoon Damrey rainfall over the ocean, howeverafter landfall produced rainfall over the land. Comparison of two rainfall datasets revealing that TRMM data is better for identifying heavy rainfall due totyphoon.
