Abstract
The climate variability over the maritime continent is important in affecting the global climate. However, the available Global Climate Model output data cannot capture climatic detail of the region that may lead to inaccurate climate information. The improvement in the climate information over this region is expected to benefit both research and society. Therefore, we plan to apply downscaling experiment using regional climate model system RegCM4.6. The model has been being shown to be quite good to study the climate variability in various regions. The proposed research aims to evaluate the performance of the RegCM4.6 to reproduce the climate variability over the chosen region for given initial and lateral boundary conditions. We focus to investigate the temperature, precipitation, and surface wind as the three of essential climate parameters in the tropical climate research. Moreover, the results are expected to give more reliable climate information, especially related to the extreme events happened over the region and the possible impact of climate change to anticipate the more severe societal effects in the future.
