Extreme weather can be seen from rain that falls with varying intensity from moderate to extreme that can also occur sporadically or persistentlyJakarta (ANTARA) - The National Research and Innovation Agency (BRIN) reminded the public to be aware of the impact of Tropical Storm 93S that could trigger extreme weather in Sumatra and Java.
"Extreme weather can be seen from rain that falls with varying intensity from moderate to extreme that can also occur sporadically or persistently," researcher from the BRIN Center for Climate and Atmospheric Research Dr Erma Yulihastin noted in a statement here, Thursday.
Yulihastin later explained that sporadic rains with high intensity occurred in short durations of less than one hour. Meanwhile, persistent rain occurs at a duration of more than six hours, with intensity varying from light to extreme.
In addition to sporadic and persistent rains, extreme weather in the form of strong winds also poses a threat to several areas in Sumatra, especially northern Sumatra, she stated.

"Extreme rains accompanied by strong winds have the potential to occur in the area due to the formation of storms with patterns of rain streaks or squall lines that initially formed along the west coast of Sumatra from Aceh to Bengkulu," she remarked.
A squall line storm that forms in northern Sumatra can potentially continue to spread to the northeast until it reaches the Malacca Strait and causes extreme rain and strong winds in several areas in Malaysia, she stated.
This condition can last up to several days since it is influenced by preconditions for the formation of vortex storms in the Indian Ocean close to northern Sumatra.
"People in northern Sumatra must increase their awareness of the increase in extreme weather that can occur due to the formation of storm," she stated.
She explained that the weather in Indonesia still had a pattern similar to October 2022 that was more influenced by the dynamics of vortex storms in the Indian Ocean.
The formation and decay of this vortex storm will be the main controller of the weather, so heavy rain and strong winds can potentially occur in western Indonesia, especially Sumatra and Java.

BRIN's Center for Climate and Atmospheric Research developed the Mid-Term Indonesian Early Seasonal Study (Kamajaya) based on data from the Decision Support System to determine Indonesia's seasonal potential.
Data shows that during the first basic period on November 1-10, vortex storms can potentially form in the Indian Ocean near Sumatra. This is evidenced by monitoring the Himawari cloud satellite.
"Based on monitoring results on Thursday, there has been a formation of vortex storm that has been classified as a tropical depression or tropical cyclone seed called 93S in the Indian Ocean near central Sumatra," Yulihastin added.
