Indonesia has complex atmosphere and the weather processes are unique
where one of them is Mesoscale Convective Complex (MCC). MCC is a system
belongs to Mesoscale Convective System which has cloud coverage minimum
100.000 km2 . MCC is a main system responsible for extreme weather and heavy
rainfall in some areas. Hence, it is required to do research relating to MCC’s
movement by choosing case study on 8-10 February 2016 in bangka Belitung.
MCC’s movement was identified using Himawari-8 satellite data, while output of
WRF-ARW was used for Vertical Wind Shear , CAPE, and total rainfall analysis.
Result shows that high Vertical Wind Shear and moderate CAPE are favourable
condition for MCC development. MCC in this study moves towards region which
values of Vertical Wind Shear and CAPE are greater than the original territory and
nearly in the same direction with Vertical Wind Shear Vector. After verified, output
of WRF-ARW was fine enough to simulate CAPE and Vertical Wind Shear but
lack of accuracy in simulating rainfall.
