Jakarta, shesocial Indonesia
–
Parts of Indonesia are experiencing a transition period from the dry season to
rainy season
.People are asked to be aware of extreme rain which is predicted to increase.
The Meteorology, Climatology and Geophysics Agency (BMKG) mentions that in this period rain with moderate to dense intensity which tends to be sporadic and short -duration has the potential to occur in the afternoon until late at night.
According to BMKG this condition cannot be separated from the influence of various atmospheric dynamics that are taking place in the country’s territory.
This condition is said to be inseparable from the influence of various atmospheric dynamics that are taking place in the country.The negative value of Dipole Mode Index (DMI), and the warmth of sea level temperatures in the waters of Indonesia triggered an increase in convective activity.
In addition, Kelvin’s wave activity, and Madden Julian Oscillation (MJO) are predicted to be active until the next week in parts of Indonesia.
This indication is also seen from the outgoing longwave radiation (OLR) value which significantly shows a negative value, indicating a strong tendency for rain cloud growth.
Then, another factor that helped strengthen the condition was the existence of cyclonic circulation which triggered the area of meeting and slowing wind speed.
Locally, the atmospheric condition also supports the increase in the potential for rain.The relatively strong lability and the humidity of the wet air became a trigger for the formation of convective rain clouds in many regions, including most of the Sumatra, Java, Bali-Nusa Tenggara, Kalimantan, Sulawesi, Maluku, and Papua regions.
“The atmospheric activity has the potential to produce rain with varying intensity, ranging from mild to thick,” said BMKG.
BMKG said the potential for significant weather in the form of heavy rain accompanied by strong winds has the opportunity to occur in most of the regions of Sumatra, Java, and the central to east Indonesia regions.
Alert extreme rain
National Climatology Expert Research and Innovation Agency (Brin) Erma Yulihastin said in Java, especially Bogor and Bandung, predicted to experience rain with an average of more than 200 mm.
According to him Bogor has the potential to experience rain with an average of 10 days reaching 255 mm in Dasarian II in September.At the peak next month, it is estimated to surge twice.
The same thing has the potential to occur in Bandung.In October, rain in the region will reach 490 mm.
“Just like Bandung, Bandung, why are these two concerns? Because we see that the potential for extreme weather is indeed high in both regions. Yes, Bandung has also experienced the rainy season in the first decades in October, and Bandung will also experience the same peak, it is almost 490 millimeters for the second dasarian,” Erma said, quoting
CNBC
.
While in Jakarta, high rainfall will also occur this month.However, for its intensity it will not be as high as the previous two regions.
The peak of the rainy season in Jakarta is also predicted to occur in October.But it will be a little late from Bogor and Bandung.
“The rainfall is not as high as Bogor, but has increased gradually, with the October the third dasarian it can reach 193 millimeters, meaning that it is almost 200 millimeters,” he explained.
