Abstract

Abstract: The correlation between sea surface temperature (SST) anomaly, sea surface dynamic height (SSH) anomaly and temperature profile anomaly is constructed by using regression analysis, which is based on the historical temperature-salinity profiles. Combined with the correlation, satellite SST and satellite SSH reconstruct a three-dimensional temperature field, whose temporal resolution is daily and spatial resolution is 0.25白0.25? near Taiwan Island. Compared with the observational temperature profiles, the reconstructed temperature field can represent the property and structure of the temperature field and better describe meso-scale variability of the ocean temperature filed. This analysis field can serve as not only the initial field of a numerical model but also pseudo temperature observation, which may be assimilated into the system of ocean reanalysis and forecast in order to improve the output.

Key words: satellite sea surface temperature, sea surface height, reconstruction of temperature profile
