LW Up is a longwavethat emitted from sea surface to atmosphere. Variability of upper ocean mixed layerhas influence on ocean thermal capacity and then affected LW Up variation. The areaof interest of this research was west of Sumatra waters. Vertical temperature profiles, sea surface temperature (SST) and LW Updata from 2000 to 2015 were used. Mixed layer depth (MLD) was computedbyThreshold Method based on temperature profiles with 0.31°Ctemperature criterion (ΔT). The results show high LW Up flux occur during shallow MLD and low LW Up occur when MLD become deeper. Correlation between SST and LW Up give a fine value about 0.9 in all station. Good correlation coefficient between MLD and LW Up found in station 1 (-0.81) and 9 (-0.77) with 1 month lag. This results suggest that shallow (deep) MLD followed by high (low) SST so that the result is increase (decrease) LW Up by 1 month lag. Small correlation between MLD and LW Up found in area near equator region. Indian Ocean circulation, westerly wind, and Wyrtki jet are possibly causing the small correlation in equator region.[/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]Good correlations,Indian ocean,Mixed layer depths,Radiation fluxes,Sea surface temperature (SST),Temperature profiles,Vertical temperature profile,Westerly winds[/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 result is part of research activity “The Ocean Current System of Indonesian Waters and its effects on Marine Fisheries Production” funded by Research and Innovation, Bandung Institute of Technology 2017.[/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=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1742-6596/1127/1/012036[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
