Potential Strong Winds in These 3 Islands, What Causes it?

he Center for Atmospheric Technology Science of the National Institute of Aviation and Space (PSTA LAPAN) states, two tropical cyclones in the Pacific Ocean near Japan triggered very strong winds to blow. As a result of strong winds of more than 10 meters per second, the impact is homogeneous and evenly distributed throughout Java, southern Sumatra and southern Kalimantan.

According to PSTA LAPAN atmospheric science researcher Erma Yulihastin, the presence of strong winds was accompanied by dry air so that for the next few days the rain was still reluctant to visit Java and its surroundings.

"In addition, there is a mass meeting of water between humid and dry in western and southern Kalimantan around central Sumatra, causing a lot of rain in the region," Erma said when contacted by telephone, Bandung, Tuesday, October 22, 2019.

Especially for Kalimantan, added Erma, the mass meeting of water vapor was also strengthened by the formation of a convergence region, namely low pressure on the west coast of Kalimantan so that heavy rains for several days would flush Kalimantan.

Erma explained for the Bualoi Tropical Cyclone, her condition is still at the initiation or formation stage. Meanwhile, for Typhoon Neoguri is still in the tropical storm category.

Meanwhile, the Geophysical Climatology Meteorology Agency (BMKG) of Bogor Climatology Station stated that based on the wind distribution pattern of 3,000 feet per date on Sunday (10/20/2019), in general winds that pass through West Java are still dominated by winds from East to Southeast originating from a high pressure center (1,020 mb) around the Indian Ocean west of Australia to a low pressure (1,005 mb) in the Indian Ocean east of Africa.

"There is a Typhoon Negouri (980 mb) in the Pacific Ocean northeast of the Philippines and tropical cyclone (TS) Bualoi in the Pacific Ocean in the east of the Philippines. Significant differences in air pressure between the BBS and BBU areas cause the formation of strong wind currents in the narrow lane in the atmosphere (Jetstream), "said forcaster on duty Bogor Climatology Station Leni Jantika Haswan in his official statement.

Leni said based on the pattern of the distribution of wind layers of 925-700 mb, it was observed the Jetstream trajectory that extended from the Arafura Sea south of Papua to the Java Sea. This condition causes an increase in the average daily maximum wind speed in most of West Java.

In conclusion, said Leni, in October 2019 several regions of West Java entered a transition period from the dry season to the rainy season so that the potential for extreme weather events including strong winds.
