Characteristic of anabatic wind in Bandung basin observed by AWS

Abstract

A field campaign has been done for the wet season in 2015 to identify the pattern of local circulation such as anabatic wind at Bandung basin. In this field campaign, the Automatic Weather Stations (AWS) were installed at seven points from the north until the south region of Bandung basin. The result of this research defines the pattern of anabatic wind in Bandung basin into three categories: the pattern on weak convection, strong convection, and strong convection with rain event. On weak convection condition, after 12.00 LT, the anabatic wind tended to move to the north region of Bandung basin. The wind still moved to the north and south region, on strong convection and strong convection with rain event condition after 12.00 LT. However, after 15.00 LT the wind on strong convection with rain event changed to become northward. On strong convection and strong convection with rain event, the pattern of anabatic wind was influenced by the convective activity in the north and south region of Bandung basin. Whereas on weak convection condition, the pattern of anabatic wind was not influenced by the convective activity.

Mechanism of Initiation and Regeneration Convective Cell in Bandung Basin, Indonesia

“…Local convective activity influences the precipitation in the Bandung Basin (Dewi and Trilaksono, 2018;Fitriani et al, 2019;Oigawa et al, 2017) which can be caused by anabatic and katabatic winds (Kombara et al, 2019). Northern convective system produce earlier precipitation rather than the southern convective system (Dewi and Trilaksono, 2018).…”
