BMKG: Australian Monsoon Due To Cold Temperatures In DIY

YOGYAKARTA - The Yogyakarta Meteorology, Climatology and Geophysics Agency (BMKG) revealed that the minimum cold air temperature to reach 19 degrees Celsius in the Special Region of Yogyakarta was influenced by the movement of the Australian Monsoon wind.

Head of the Yogyakarta BMKG Meteorological Station, Warjono, said that the Australian Monsoon was a movement of winds originating from the Australian plains to the Asian plains through the territory of Indonesia.

"This Australian platform brings cold and dry air masses," said Warjono as quoted by ANTARA, Friday, August 25.

He continued, when cold air masses pass through Indonesia, especially the southern part of Indonesia, Java, Bali, NTT, including DIY, will cause rare rain and minimal cloud cover.

With this minimal cloud cover, he said, solar radiation during the day will be directly forwarded to the surface of the earth so that people will feel the hot heat.

Meanwhile, at night, continued Warjono, people will feel colder air temperatures because there is no solar radiation.

Heat on the earth's surface received during the day, he said, is immediately released into the atmosphere or space without any barriers.

"Because the cloud cover is minimal, so we will feel colder air temperature," he explained.

Head of the Yogyakarta BMKG Climatology Station, Reni Kraningtyas, said that the cold air temperature on Friday (25/8) morning at 06.00 WIB in DIY was recorded at 19.7 degrees Celsius, triggering the emergence of fog in Sleman Regency and its surroundings.

According to him, the formation of fog is a natural phenomenon that often occurs, namely when the air content near the ground surface is quite saturated with water vapor and usually the water vapor content in the air has almost 100 percent humidity.

"After we checked the humidity, the air was quite high, about 98 percent and the air temperature this morning at around 6 am was quite cold, 19.7 degrees Celsius, so it was possible to cause fog in Sleman and its surroundings," said Reny.
