AB: In the middle and southern regions of the Indian sub-continent, 80% of the yearly precipitation is caused by the Asian monsoon, an intensely rainy season occurs from June to September every year. Weather models, during the monsoon season, have varying degrees of success at predicting the locations and amount of rainfall to be expected. In late July 2005, a record-breaking precipitation event occurred in Mumbai, western India, but the weather forecasting models failed to identify the heavy rainfall event, and the flooding did major damage. Anomalies in precipitation in the monsoonal regions could be the consequence of anthropogenic activities, such as urbanization and the changes in forested to agricultural crops and associated land use land cover changes. We report results on the impact of landuse land cover changes on the heavy precipitation episode simulations in the western Indian monsoon region using a mesocale model system. The primary area of interest is focused on domains based on the Arabian Sea Monsoon Experiment (2002) and then the validated model is applied to the Mumbai heavy precipitation case.
