Abstract

The province of Papua is located in the eastern region of Indonesia. Catastrophic storms and tropical cyclones have increased in frequency in this area in recent years. It is crucial to understand the effects of tropical cyclones, particularly how they affect the contribution of solar radiation management (SRM) to abnormal temperatures during tropical cyclone events in eastern Indonesia. We investigate the effects of SRM on anomalous temperature in areas that are commonly affected using simulations from the Geoengineering Model Intercomparison Project (GeoMIP) and data from the European Centre for Medium-Range Weather Forecasts Re-Analysis 5 (ERA5). This study aims to investigate the impacts of abnormal temperature and propose potential solutions. The tropical storm Surigae, which made landfall on April 18, 2021, had a significant impact on the area, particularly on Timor Island and Sumba Island. We used the ERA5 model to investigate the temperature-related atmospheric dynamics during these tropical cyclone events. Additionally, we evaluated the temperature data and compared the outcomes using GeoMIP's bias correction. The findings indicate a strong correlation between the two datasets and an overall declining trend.
