Characterization of Sea Surface Height in the Andaman Sea

Abstract

The sea surface height in the Andaman Sea observed during October 1993 to July 2013 from TOPEX/ERS/Jason1 is investigated by using empirical orthogonal function (EOF) analysis, wavelet analysis and least square linear regression. The results of EOF analysis show the first two modes of sea surface height which are accounted 65.23% and 15.36% of total variance, respectively. The spatial pattern and time series are shown in this research. Moreover, the trend of sea surface height has been increased with rate of 11.06 mm/year.
