In order to investigate the influences of MJO known as the intraseasonal oscillation (30-90 days), analysis of the data was carried out after 10-100 days band-pass filtering. The analysis results show that the intraseasonal oscillation SSHA along the coasts of Sumatra, Java, and Lesser Sunda Islands generally have a spectral peak at 91 days associated with the spectral peak of the MJO, except for Sunda Strait (61 days), southern coast of West Java (55 days), Sawu Sea (58 days), and Ombai Strait (100 days). Further analysis suggests that the MJO phase 3 generates Kelvin waves propagating eastward along the coasts of Sumatra, Java, and Lesser Sunda Islands with phase speed ranging from 2.56 to 3.85 m/s.[/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]Band pass filtering,Hybrid coordinate ocean models,Intraseasonal oscillations,Kelvin wave propagation,Madden-Julian oscillation,Outgoing longwave radiation,Sea-surface height anomalies,Spectral peak[/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][/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/10.1088/1755-1315/339/1/012029[/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]
