Using Convection Permitting Models to Improve the Forecasting of High Impact Weather in Southeast Asia

The Maritime Continent is particularly exposed to high impact weather associated with tropical cyclones, monsoon systems, MJO and other tropical waves. Recent advances in computing power and the development of convection permitting models now make it possible for forecasters to use highly detailed spatial and temporal information derived from models. This presents new challenges to the forecaster that were not necessarily relevant to large-scale, coarse resolution global models in the past. This poster will describe the process by which these models are being used and assessed by forecasters, and how this assessment informs the model development process. One unique challenge for the quantitative evaluation of models is the suitability of traditional observational methods for comparison to model fields. We address these challenges by comparison of multiple sources of precipitation estimates, and through exploitation of new satellites such as Himawari-8.
