BMKG explains differences in high heat temperatures in Indonesia and India

Jakarta, CNN Indonesia

hot temperature Recently, high rates have occurred in a number of countries, such as Indonesia and India, rousing interest from local experts in a comparison.

The Agency for Meteorology, Climatology and Geophysics (BMKG) compared the hot temperatures that occurred on the territory of Indonesia and India and revealed the cause.

The hot and cold temperatures have been felt by people in several parts of Indonesia since early May 2022. This condition has led some people to associate it with the heat wave that was occurring in India at the same time.

During this period, at least 2 to 8 BMKG weather stations reported maximum air temperatures of over 35 degrees Celsius from BMKG data sets. The weather stations Kalimaru (East Kalimantan) and Ciputat (Banten) even recorded a maximum temperature of around 36 degrees Celsius for several days in a row.

Nevertheless, the BMKG ensures that hot temperatures in Indonesia do not fall into the category of heat waves, as they do in India.

“Hot temperature events in Indonesia are not categorized as heat waves like in India because they do not meet the World Meteorological Agency’s (WMO) definition of extreme meteorological events, which are anomalies 5 degrees hotter than the climatological average maximum temperature at one location and lasted at least 5 days,” said Plt. Deputy BMKG Climatologist Urip Haryoko in a BMKG publication.

The BMKG explained that due to certain weather upheavals, heat waves generally also occur on a large scale and cause hot air masses to accumulate. Therefore, the occurring hot temperature is regarded as a natural thing.

In the climatological analysis, most air temperature observation locations in Indonesia show two maximum temperature peaks, namely in April/May and in September. This is said to be due to the influence of the apparent position of the sun and also to the dominance of early sunny weather or the peak of the dry season.

The maximum temperature of about 36 degrees is also not the highest temperature ever recorded in Indonesia, as the record for the highest temperature ever recorded was 40 degrees in Larantuka (NTT) on September 5, 2012.

“However, the temperature anomaly, which is hotter than several other regions in Indonesia, points to another factor reinforcing the air temperature peak period,” he explained.
