For Banten, Jakarta, and West Java, in general, extreme weather potential still needs to be watched out for, especially on December 30, 2022, until January 1, 2023Jakarta (ANTARA) - A new phenomenon has emerged that can trigger extreme weather on December 31, 2022, until the start of next year, the Meteorology, Climatology, and Geophysics Agency (BMKG) stated.
Specifically, the appearance of ex-Tropical Cyclone Ellie has triggered relatively significant changes to the previous weather forecast, Head of BMKG Dwikorita Karnawati noted in an online press conference on Friday.
Initially, the weather condition on December 31 was estimated to improve, she remarked.
However, the appearance of this phenomenon means that the people need to be cautious since extreme or even beyond extreme rainfall intensity may occur, she explained.

"This change is quite significant that we need to tell the public that the situation is not as good as we have predicted yesterday," she remarked.
The emergence of this ex-Tropical Cyclone Ellie in West Australia, along with other phenomena within the last week, contribute to increase in heavy to very heavy rainfall, she stated.
These other phenomena include the Asian monsoon, cold snaps, equatorial cross currents, and Madden Jullian Oscillation (MJO) along with the Kelvin Wave and Rossby wave phenomenon.
Based on this situation, until January 4, 2022, people need to watch out for extreme weather potential for Java in general, especially from December 30, 2022 to January 1, 2023, she remarked.
"For Banten, Jakarta, and West Java, in general, extreme weather potential still needs to be watched out for, especially on December 30, 2022, until January 1, 2023," she noted.

Karnawati expects that the Weather Modification Technology (TMC) can reduce the intensity of potential extreme weather, so that it is not as severe as forecast.
On the occasion, BNPB's Emergency Handling Deputy Major General Fajar Setiawan noted that his team plans to organize a weather modification technology operation in several new regions ahead of the 2023 New Year.
These regions include Banten, Central Java, East Java, and Bali.
"We expect that we will carry it out within a day or two. It all depends from BRIN's (National Research and Innovation Agency's) readiness with the Air Force aircraft," he elaborated.
The operation conducted by BRIN in West Java and Jakarta within the last few days has been proven to reduce rainfall with extreme potential.
