Scientific Explanation of the Cause of High Rainfall in Jabodetabek Causing Flooding |  merdeka.com

Merdeka.com – The Chief Executive of the DKI Regional Disaster Management Agency (BPBD) JakartaIsnawa Adji conveyed the results of a temporary analysis of the cause of rain on Friday (15/7) and Saturday (16/7) for the Greater Jakarta area, namely the spread of wet air masses around Java Island.

This analysis was delivered after DKI BPBD coordinated with BMKG.

“In general, global factors that affect atmospheric conditions that cause rain are the propagation of wet air masses around the island of Java due to atmospheric waves such as Rossby waves and Kelvin waves,” Isnawa said, Saturday (16/7).

Another factor is the intake of wet air masses from the Indian Ocean, because it is active Dipole Mode Index (IOD).

Isnawa added that the cause of the rain in Greater Jakarta from Friday afternoon to Saturday was also local factors.

“The local factor that influences is the presence of wind confluence areas around the southern part of West Java,” he explained.

Rain conditions with light to moderate intensity are expected to continue until Sunday (17/7).

From the results of the coordination, Isnawa ensured that BPBD officers were on standby to monitor inundation in all sub-districts and coordinated with the Water Resources Sub-dept. to suck up puddles with the lurah and sub-district head.

“I also ordered BPBD to coordinate with the Indonesian Red Cross (PMI), the Social Service and regional ranks to monitor developments.”
