This study aims to investigate the extreme rainfall due to tropical cyclones. We focus on three tropical cyclones (TC) that struck in eastern Indonesia, i.e., Surigae TC (April 2021), there has been a notable increase in the frequency of tropical cyclones and severe weather phenomena in this area. Understanding the ramifications of tropical cyclones, particularly their influence on weather patterns, including extreme rainfall, is crucial. The tropical cyclone Surigae, which made landfall on April 16 2021, considerably affected the region, particularly on Timor Island and Sumba Island. We employed the ERA5 and SRM model to analyze the atmospheric dynamics related to rainfall during these tropical cyclone events. Additionally, we applied Bias correction from GeoMIP to evaluate the rainfall data and compare the outcomes. Our analysis using Solar Radiation Management (SRM) shows that the data from both sources correlate well and indicate a decrease in rainfall over eastern Indonesia during the tropical cyclone. Potential biases in the GeoMIP approach, such as the simplification of cloud-aerosol interactions and the assumptions underlying the SRM mechanism, may contribute to underestimating precipitationThe findings indicate a strong correlation between both datasets, with a general decrease trend observed. *Source: AIP Publishing * -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
