ANALYSIS OF EXTREME RAINFALL ANOMALY IN INDONESIA DURING AUGUST 2021
According to Global Precipitation Climate Project (GPCP) data, rainfall anomaly in Indonesia during August 2021 is extreme (exceed 95th percentile). The cause of the extreme rainfall anomaly is still unknown, so the purpose of this research is to unveil the cause of the extreme rainfall anomaly. Thi...
