Abstract

The Pacific Ocean deep sea height data around latitude 20 N from Jason-1 satellite was analyzed in terms of standard deviation (std) and fractal dimension during a 90-day period that included the coronal mass ejection event of 2003 Oct 29 where a peak solar energetic particles of about 30,000 pfu was measured. The surface height standard deviation series was observed to have two peaks that corresponded to two typhoon events of Oct 25 and Nov 26, 2003. The cross correlation of the height-std series and average-height series showed a positive correlation with time delay. The fractal dimension of the height series peaked on Nov 1 (fractal dimension ~1.96 with a background 90-day average of ~ 1.81) and no corresponding peak was observed in the other time series data. Computer simulation of the fractal dimension of a finite random series suggested a standard deviation of about 0.071. Annual and long-term trends of the fractal dimensions were also found and investigated. The possible contribution of coronal mass ejection to the surface height series fractal dimension and the height correlation to chlorophyll were discussed.
