BRIN: Terik And Rainy Nights Indications At The End Of The Transition Season

JAKARTA - Researcher at the BRIN Center for Climate and Atmospheric Research, Eddy Hermawan, said the phenomenon of hot heat during the day and rain fell at night or early morning indicating that Indonesia was entering the end of the transition from rainy to dry season.

"So the hotter the temperature is generally followed by rain at night, although the nature of the rain is not as big as in general during the rainy season. This is an indication that usually occurs at the end of the first transition season," said Eddy as quoted by ANTARA, Tuesday, May 14.

The Meteorology, Climatology and Geophysics Agency (BMKG) predicts that the start of this year's dry season will occur from May to August 2024.

Eddy said the world is currently experiencing heat waves. Areas exposed to heat waves are land-dominated areas or countries, such as India, Thailand, and areas such as Africa or Brazil.

According to him, heat waves are a condition where the average temperature situation exceeds the normal threshold for more than 30 to 40 years.

If the temperature for three decades ranges from 27 to 28 degrees Celsius, then it jumps with a deviation above five and lasts permanently for four to five days, then the condition is defined as a heat wave.

Indonesia's geographical position is two-thirds of the sea and a third of land with five large islands and 17,548 islands where each island produces local convection and regional convection that forms clouds.

"As a result, Indonesia is relatively safe from the dangers of heat waves," said Eddy.

He admitted that he did not know for sure when the peak of the summer would end soon.

However, if the analysis is based on the behavior of the Indian Ocean Dipole (IOD) data in the Indian Ocean, specifically for the western region of Indonesia and the North Coast (Pantura) of Java Island, the beginning of the hot conditions has started last April and continues to climb until it reaches the peak around July 2024.

This is exacerbated by the start of blowing easterly winds moving across the territory of Indonesia as the solar position moves away from the equatorial line since March 21, moving temporarily towards the northern hemisphere.

"So, there are strong indications that this hot condition will continue," said Eddy.

In addition to the condition of water vapor in the western region of Indonesia which is pulled to the east of Africa's east coast as well as easteastern winds originating from the desert in northern Australia have begun to crawl into Indonesian territory.

The main gate that will accept this condition is the East Nusa Tenggara region, followed by West Nusa Tenggara, Bali, East Java, and so on.
