Java Island experienced a temperature drop following a weather phenomenon called a dry intrusion, the Meteorology, Climatology and Geophysics Agency (BMKG) said on Tuesday.
Residents of Java complained via Twitter on Tuesday about the drop in temperature, which went as low as 12 degrees Celsius. Many people find this phenomenon odd since Indonesia has entered the dry season.
According to the head of the BMKG's Weather Forecast subdepartment, Agie Wandala Putra, this weather phenomenon occurred as a result of several factors, such as the dry intrusion. Dry intrusion is a term to describe dry weather intruding a certain area.
The dry intrusion, Agie went on to say, was currently happening on several islands across the country such as Java, Bali, Nusa Tenggara, and other areas south of the equator.
He also told kompas.com on Tuesday that this could happen due to the absence of clouds when rain occurred, causing the heat radiation from the sun to return to the atmosphere easily.
Nevertheless, Agie said this was a normal occurrence. The temperature also differs in each area. The BMKG data also shows that the coldest temperature recorded was in Tretes, Malang, East Java at 12.2 degrees. (dpk)
