Abstract Details

2018, Master of Science, Ohio State University, Atmospheric Sciences.
The need for good quality information on climate and its future changes have become increasingly important for Indonesian society. Of particular interest are analysis and predictions of rainfall at pertinent spatial scales. An option is the use of regional climate models as a physics-based downscaling tool to retrieve higher spatial resolution information from coarser present and future climate datasets. In order to verify that simulations provide added values that result in an appropriate representation of the state of climate at finer spatial resolutions, the adoption of regional climate models requires prior optimization. The performance of a regional climate model (WRF, Weather Research and Forecasting Model) in simulating precipitation over Indonesia is examined by a series of sensitivity experiments using different parameterized convective physics. Among tested schemes, the best performance is provided by the Betts-Miller-Janjic parameterization. Regional simulation results present some added value in simulating rainfall-related climate indices but show low skill in recreating the annual rainfall pattern. A series of regional climate simulations using the Betts-Miller-Janjic convective scheme forced by a future climate projection dataset show changes in rainfall aligned with previous studies.
