What's with the September Rain?
03 Sep 2018 • Read : 120 x ,

The State Aeronautics and Aviation Institute (LAPAN) said that the typhoon of Jebi in the northeast Pacific Ocean of the Philippines triggered rain in Indonesia. In fact, estimates of weather conditions in Indonesia are still in the dry season ahead of November.

According to Lapan's Atmospheric Science Researcher Center for Science and Atmospheric Technology (PSTA), Erma Yulihastin, the rain that fell a few days ago in the dry season is expected to last for the next three days. This is because the position of the center of the typhoon Jebi, which is now moving closer to Taiwan, still has a remote effect which moves the collection of confective clouds that pass to Indonesia.

"So we can feel the effect is so significant cloud growth. Confective clouds or rain and rain clouds themselves that occur almost evenly in the Java Sea region since Thursday, two days ago," said Erma Yulihastin, Bandung, Sunday, September 2, 2018.

Erma said a few days ago, the impact of typhoon Jebi caused evenly decreasing rainfall with different intensities and durations on the island of Java which began from evening, night to morning. While on Sunday (09/02/2018) rain that fell evenly only occurred in West Java, while in Central Java and East Java it did not rain.

Erma explained that even though there was rain falling in early September 2018, it was not yet certain that the rainy season would enter Indonesia. The reason, said Erma, is that as long as there is a typhoon, the confective clouds or rain clouds will not form and move across Indonesia from the south to the north.

"Sumatra Island also experienced the formation of rain clouds not only in Java, then Kalimantan. But the most evenly distributed, namely in Java," said Erma.


LAPAN said that if you look at the general conditions of weather in the Pacific and Indian Ocean regions, it is still normal. Based on LAPAN satellite observations in the two regions there was no weather disturbance. However, disruptions in the form of typhoons that have impacted for several days and the waves of MJO (Madden Julian Oscillation) which are naturally formed from the interaction systems of the sea and atmosphere must remain vigilant.
