For an example, there was an oil rig accident, which make it run aground due to wind gust event in the Mahakam Block, East Kalimantan on 24 February 2011. The wind gust event was caused by a thunderstorm outflow from a convective cloud that located to the west of the Mahakam Block. In this study, a wind gust simulation that caused by thunderstorm outflow was performed using Weather Research and Forecasting – Advanced Research WRF (WRF-ARW) model. The convective cloud associated with the wind gust event was successfully simulated using the WRF model. When reaching the Mahakam Block, the convective cloud has already begun to enter dissipation stage and its thunderstorm outflow begun to the early mature stage. While entering the mature stage, the thunderstorm outflow produces the wind gust event at that time. The wind speed parameters of the WRF model output show similar results with observational data in five observation stations in the Mahakam Block. The average increase in the speed of the wind during the wind gust event is at least 70% at the locations of the five observation stations.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Thunderstorm outflow,Wind gust,WRF-ARW[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors thank to members of Weather and Climate Prediction Laboratory (WCPL-ITB).
