Apply MM5 for studying urban heat island effect in Ho Chi Minh city

Abstract

Ho Chi Minh City (HCMC), which is the largest city in Vietnam, is one of fastest developing Urban. HCMC's population is about 6 millions, the population increase is high level, nearly 3,6%/year. The urbanization is cause of landuse change, which leading the change of climate. The purpose of this paper is study the effect of land surface on HCMC thermal environment by the numerical model. The landuse and terrain data on this study is from SRTM and MODIS. The study results show adequate agreement between the observation data and the model simulation.
