Field campaign were conducted from end of February until end of May 2017 in Bandung Basin urban area. The purpose of this research is to analyze the strong wind during severe storm (case study March 17) based on wind shear data. This strong wind are conform by the AWS ground based wind measurement from 11.00 LT until 12.00 LT with wind speed value varied from 4.5 – 12 m/s. A post processing using 2 dimensional (2D) combined shear method from the wind shear weather radar data were used to analyze the larger shear resulted from strong wind. 2D combined shear showed that local heavy storm generates from center location of Bandung from 10.50 LT then grew until 11.10 LT. Changes echo shape occur in 11.20 LT forming a v shape area with large value were spotted in the edge of the object, while varied color inside the v shape area showed a fluctuated wind shear that is also correlated with spectrum width value with more than 4 m/s. Based on the combined shear data in 11.30 LT, all of the impacted location recorded were located inside the wind shear area with two location were spotted having a large combined shear value reaching > 0.01 s-1.[/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][/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]This research were supported by the Center of Atmospheric Science and Technology, National Institute of Aeronautics and Space – PSTA LAPAN and also from Indonesian Center of Excellence Research Fund.
