| Summary: | Localized rainfall which is recorded per 10 minutes can produce a different plot for each gridded rainfall product. Previously, there have been studies that analyzed the patterns of convective activity in the Bandung Basin. However, it has not yet implemented a spatial distribution using the interpolation method that adjusts the Bandung Basin topography.
The purpose of this thesis is to identify the spatial distribution of initialization points for convective cell regeneration in the Bandung Basin from gridded data generated using the Ordinary Kriging, Barnes, Cressman, Linear, and Radial Basis Function (RBF) interpolation methods, to determine the interpolation method that is suitable for the Bandung Basin topography, and to compare the results of gridded data with the Himawari 8 Satellite Imagery and the Global Precipitation Measurement (GPM) radar for evaluating convective cell regeneration analysis.
The gridded rainfall products show that the initiation of convective cell regeneration in the Bandung Basin can occur from the central, north, east, south, and west directions, both in mountainous and valley areas. The Cressman method is the most appropriate method for the Bandung Basin topography. The results of the grid data product are different when compared with the Himawari 8 Satellite Image data and cannot be compared with the GPM radar data. Making gridded rainfall products is a very important step to do in analyzing convective cell regeneration because it can show a realistic picture of the study area. |
