Analysis of SST Spatial and Temporal Characteristics in the North Pacific Using Remote Sensing Data.

Using the AVHRR OISST data from 1982 to 2019, the spatial and temporal characteristics of SST in the North Pacific Ocean were analyzed. The relationships between SST (Sea Surface Temperature) and SLP (Sea Level Pressure) as well as SSWF (Sea Surface Wind Field) were also discussed based on the ERA5 data. The study showed that the mean value of SST increased slowly at a rising rate of 0.12 degrees C/10yr during 1982-2019. EOF analysis showed that the dominant modes in the North Pacific were ENSO mode, consistent warming mode and dipole mode. There was a positive correlation of 0.58 between SLP and SST in the Aleutian low pressure area, while there was a negative correlation relationship from east Hawaiian Islands to the California seas. SST was mainly influenced by easterly winds in the area north of 36 degrees N, while by southerly winds in the sea south of 36 degrees N.
