The result of atmosphere dynamic analysis released by BMKG’s Ahmad Yani in Semarang showed that the Madden-Julian Oscillation (MJO) phenomenon is still active in some parts of IndonesiaCilacap, C Java (ANTARA) - Several regions of Central Java could likely experience extreme weather in the subsequent three days, according to a warning issued by the Meteorology, Climatology, and Geophysics Agency (BMKG).
"The result of atmosphere dynamic analysis released by BMKG’s Ahmad Yani in Semarang showed that the Madden-Julian Oscillation (MJO) phenomenon is still active in some parts of Indonesia along with the Kelvin and Rossby Equatorial wave phenomenon that can contribute to increasing the cloud cover," Rendi Krisnawan, a weather analyst at the BMKG Station in Tunggul Wulung, Cilacap, Central Java, stated on Tuesday.
The Tropical Cyclone Warning Center (TCWC) of BMKG in Jakarta detected the Tropical Cyclone Seroja in Sawu Sea southwest of Timor Island and seeds of the tropical cyclone 90S in the Indian Ocean southwest of Sumatra Island.
The intensity of the tropical cyclone and tropical cyclone seeds tends to strengthen in 24 hours and move away from the Indonesian territory, he remarked.
"The tropical cyclone and tropical cyclone seeds can indirectly contribute to a significant rise in atmospheric instability. In addition, supported by unstable air mass and high air humidity from the bottom to the upper layers, it could potentially increase the growth of clouds and drive wind speed in several parts of Central Java," he remarked.
On the basis of the aforementioned condition, BMKG’s Ahmad Yani in Semarang has forecast extreme weather and high-intensity rains along with flashes and lightening as well as strong winds to potentially affect several parts of the province in the next three days.
