YOGYAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) appealed to residents in the Special Region of Yogyakarta (DIY) to be aware of the potential for hydrometeorological disasters due to moderate to heavy rain accompanied by lightning or lightning and strong winds which are predicted to occur for the next three days.

"Be aware of the potential for moderate to heavy rain which can be accompanied by lightning and strong winds that can trigger hydrometeorological disasters in the form of fallen or broken trees, floods, and landslides," said Head of Yogyakarta Meteorological Station Warjono as quoted by ANTARA, Sunday, March 17.

Warjono said that based on the results of the analysis of the latest atmospheric dynamics, the BMKG Yogyakarta Meteorological Station identified low pressure centers in western and northern Australia.

This phenomenon, according to him, formed a meeting of wind currents or convergence in Java and southern Javanese waters blowing from southwest to northwest at a speed of 30 to 50 km per hour.

In addition, the Madden Julian Oscillation (MJO) phenomenon or the phenomenon of tropical atmospheric waves was observed in Phase 5 (Maritime-Continent) and atmospheric waves Rossby Ekuator in central and eastern Java which contributed to the process of forming rain clouds in Indonesia.

Meanwhile, the Sea Face Temperature (SML), both on a daily and weekly scale in the Java Sea and South Indian Ocean, Java, continued Warjono, was observed to be warm at 29-31 degrees Celsius.

"The sea level temperature anomaly was observed to be positive (warm) at 0.5-2.5 degrees Celsius, thus increasing the potential for evaporation or water vapor content in the atmosphere," he said.

Based on the results of the latest analysis of the vertical profile, he said, the humidity in the DIY area at an altitude of 1.5-3.0 km ranges from 50-90 percent (wet enough), which causes the potential for rain cloud growth in the DIY region in the afternoon, afternoon, and evening.

The BMKG of the Yogyakarta Meteorological Station detailed that on March 17, 2024, moderate to heavy rain that could be accompanied by lightning or strong winds occurred in the cities of Yogyakarta, Sleman, northern Bantul, Kulonprogo, and northern and eastern Gunungkidul.

Next on March 18 a similar potential in the cities of Yogyakarta, Sleman, northern Bantul, northern Kulonprogo, Gunungkidul. Then on March 19, 2024, the potential occurred in northern Sleman and northern Kulon Progo.
