Hot Temperature Affected By Climate And Amplified Atmospheric Dynamics

JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) explained that hot air temperature is influenced by climatological factors and amplified atmospheric dynamics on a regional scale and meso scale.

Acting Deputy of BMKG Climatology, Urip Haryoko, explained that the analysis of surface temperature measurements from 92 BMKG stations in the last 40 years showed an increase in surface temperature at varying rates.

In general, the trend of increasing surface temperature is more pronounced in the western and central parts of Indonesia. The eastern part of Sumatra Island, northern part of Java Island, Kalimantan and northern Sulawesi experienced an increasing trend of more than 0.3℃ per decade.

The highest rate of increase in surface temperature is known to occur at the Temindung Meteorological Station, East Kalimantan (0.95℃ per decade), while the lowest rate is at the Sultan Muhammad Salahuddin Meteorological Station, Bima (0.01℃ per decade).

The surface air temperature in Jakarta and its surroundings is increasing at a rate of 0.40 - 0.47℃ per decade.

"From this analysis, it is clear that the occurrence of hot air temperatures this time is indeed influenced by climatological factors amplified by atmospheric dynamics on a regional scale and meso scale, this is what causes the air to seem more 'stuffy' and raises questions, even public unrest (besides stifling heat). " said Urip as reported by Antara, Tuesday, May 17.

Urip said the occurrence of high daily temperatures in Indonesia is often attributed to climate change. This statement is not wrong, although it cannot be completely justified either.

In each unit of weather events, it is not directly attributable to global warming or climate change. Climate change must be read from a long series of climate data, not just from a single event.

However, the trend of hot temperature events can be studied in a long data series, whether there is a change in the pattern, both the magnitude of the heat and the frequency of occurrence.

BMKG assures that this condition does not include dangerous extreme conditions such as a heatwave, although the public is still advised to avoid dehydration and maintain health.
