JAKARTA, iNews.id – The incidence of cold temperatures was felt in several areas in East Java during the dry season. Phenomenon This seems to raise questions in the community.
East Java residents who experience this actually need not worry. Because according to BMKG, the phenomenon of cold air temperature is a natural phenomenon that usually occurs in the peak months of the dry season (July – September).
“This condition is commonly referred to as the bediding phenomenon,” the BMKG wrote on its Instagram account.
The bediding phenomenon occurs because currently the Java to NTT region is heading for the peak period of the dry season, which in this period is marked by the movement of the dominant wind blowing from the east originating from the Australian continent.
BMKG explained that in July this Australian region was in the winter period. The nature of the air mass in Australia is cold and dry.
The existence of a pattern of relatively high air pressure in Australia causes the movement of air masses from Australia to Indonesia or known as the Australian Cold Monsoon.
The Australian monsoon winds blowing towards Indonesian territory through the waters of the Indonesian Ocean which has a relatively cooler sea surface temperature, resulting in cooler temperatures in some areas in Indonesia, especially the southern part of the equator (Java, Bali and Nusa Tenggara).
The decrease in cloud and rain on the islands of Java, Bali, NTB, and NTT has been seen quite significantly in the last few days also accompanied by a decrease in the water vapor content in the atmosphere.
