CLEAR AIR TURBULENCE MITIGATION DUE TO CLIMATE CHANGE IN INDONESIA

Rahmat Gernowo and Dwi P. Sasongko

Abstract

Natural disaster nowadays often occur in Indonesia due to climate change, especially those related to atmospheric dynamics anomalies. The latest clear air turbulence (CAT) is often experienced by air transportation. Turbulence is a very interesting phenomenon since it is very difficult to solve even though the symptoms have long been aware of. Turbulence modeling in fluid physics in the atmosphere is a very important thing and an effort to explain a problem that is hard to solve (turbulence) becomes very interesting. In this research, turbulence motion calculation was carried out by physical parameters object’s deformation motion, either horizontally, or vertically as well as atmosphere gradient wind shift based on the data of the weather from radiosonde of the research’s site. As the case study, a calculation from the phenomenon of Batik Air’s aircraft ID6890 experiencing the turbulence on 24 October 2017 will be carried out. The calculation result shows turbulence index value in the point of even was located at around 2 – 8 × 10–1s–Z showed that turbulence did occur.
