This cyclonic circulation forms an area of ​​convergence that extends into the waters of northern Aceh, from northern Sumatra to the western waters of Bengkulu, in the north of the Karimata Strait and from central Kalimantan to the south of the Karimata Strait.

“This condition may increase the potential for rain cloud growth around the cyclonic circulation area and along the converging area,” Guswanto told Kompas.com on Saturday (11/21/2020).

The results of the BMKG analysis, he continued, show that the dynamics of the unstable atmosphere in the coming week may increase the potential for rain cloud growth in various regions of Indonesia.

“This condition is reinforced by the activation of the Madden Julian Oscillation (MJO) phenomenon, the equatorial Rossby wave and the Kelvin wave in Indonesian territory in the period of next week,” said Guswanto.

“This condition is inseparable from the change of seasons, towards the rainy season in Java, which is indicated by the presence of the Asian monsoon that does come at the end of the year,” he said.

“If we look at other statistical data, actually the data on lightning incidents from July to August is mainly in the Sumatra region,” Agie said.
