Long-term variation of sea surface temperature in relation to sea level pressure and surface wind speed in southern Indian Ocean

Sea surface temperature (SST) is an essential parameter associated with fish habitat and changes in oceanic conditions. Long-term SST variation relation to sea level pressure (SLP) wind speed (SWS) was observed based on the National Oceanic Atmospheric Administration (NOAA) data of southern Indian Ocean. Mean monthly time series showed that February November were warmest coolest months, respectively. Spatial distribution 0°S–30°S warm 20°–30°C, which higher than at all other places throughout year. SLP (> 1010 millibar) SWS 12 m/s) high 20°S–40°S 45°S–50°S, strongly negatively correlated but positively SLP. yearly 2016 1948 years, respectively, during study period. Decadal 1978–1987 had highest decadal change. anomalies almost negative before 1970, positive after 2008, 2016. Southwest Ocean warmer southeast summer vice versa winter. 1948–2018 those 1948–1972 1973–2018 for 4 months.
