Extreme Rainfall Indices for Tropical Monsoon Countries in Southeast Asia

Analysis of extreme daily rainfall in southeast Asia with a gridded daily rainfall data set

The objective of this study is to estimate the daily extreme precipitation distribution in an Asian monsoon region considering orographic precipitation in mountainous areas. For this purpose, the APHRODITE data set and precipitation observations from 150 raingauges throughout Thailand were used as the main input. First, a bias-correction for underestimated precipitation in the APHRODITE data se...

Modeling the influences of aerosols on Pre - monsoon circulation and rainfall over Southeast 1 Asia

Modeling the influences of aerosols on pre-monsoon circulation and rainfall over Southeast Asia

We conduct several sets of simulations with a version of NASA’s Goddard Earth Observing System, version 5, (GEOS-5) Atmospheric Global Climate Model (AGCM) equipped with a two-moment cloud microphysical scheme to understand the role of biomass burning aerosol (BBA) emissions in Southeast Asia (SEA) in the pre-monsoon period of February–May. Our experiments are designed so that both direct and i...

Forecasting severe rainfall in the equatorial Southeast Asia

Accurate prediction of monsoon heavy rainfall events in the equatorial region has always been a challenge to weather forecasters. In this paper, forecast of a severe precipitation event that occurred over the eastern central coast of Peninsular Malaysia was attempted using the state-of-the-art Florida State University (FSU) Global and Regional Spectral Models. The sensitivity of parameterized c...
