Abstract

Characteristics of the cold pool over the Soekarno-Hatta airport site area have been documented based on the analysis of C-band Doppler radar images (6.16S, 106.64E). The cold pool phenomenon that was successfully observed originated from convective clouds. The existence of this phenomenon mostly disrupts aircraft landing activities above the Soekarno-Hatta airport area, resulting in aircraft failing to land and performing go-around maneuvers. One of the documented cold pool phenomena triggered the growth of convective clouds that resulted in flooding at the Soekarno-Hatta airport area. The results of research from lidar ceilometer observation data using cloud base height analysis showed that the cloud base height decreased after the cold pool propagation passed through the Soekarno-Hatta airport area. Analysis of cold pool energy and its propagation using wind profiler observation data calculations showed that the respective values were C^2 >= 100 m^2/s^2 and C >= 5 m/s. Analysis of the observed cold pool depth (H) shows that the cold pool phenomena that were successfully observed had an H value of >= 1300 m.
