Weather anomaly triggers frost in Dieng during rainy season

Weather anomalies triggered the frost phenomenon or locally known as “upas dew” in the Dieng highlands of Wonosobo and Banjarnegara region of Central Java Province during the rainy season, according to the Meteorology, Climatology, and Geophysics Agency (BMKG).

“The phenomenon of ‘upas dew’ generally occurs at the peak of the dry season during the period from June to August,” Head of the BMKG Meteorological Station Class II Ahmad Yani Semarang, Sutikno, noted in a press release here on Tuesday.

Sutikno explained that the air mass during the rainy season is generally humid and wet and is influenced by a fairly large Asian monsoon.

Based on data from the Automatic Weather Station (AWS) installed in the Arjuna Temple area in Dieng, weather conditions around the highlands since the start of 2022 were dominated by overcast sunny climate, with excessively hot weather.

“Rainfall is low, while the difference in air humidity between day and night is quite significant,” he pointed out.

Sutikno explained that areas with good vegetation and low plant cover are highly likely to experience upstream dew.

He noted that several areas in Central Java, including the Dieng highlands, largely experienced sunny overcast weather.

Atmospheric dynamics around the Dieng highlands during the period from Jan 1 to Jan 4 of 2022 supports the appearance of frost, as it is almost similar to the dry season.

“With such atmospheric dynamics, the likelihood is very high for the appearance of the frost phenomenon,” he added.
