Climatological trend of sea surface temperature anomalies in the south eastern mediterranean sea

Abstract EN

The Linear and quadratic regressions have been used to investigate the relationship between SSTA and time (month or year) to get the general SSTA possible trends.

Regardless the propaganda concerning increasing or oscillating of climate parameters.

The present work depends on analyzing series of observed data (61 years, January 1948 to December 2008) for a limited geographic area (south eastern Mediterranean Sea in front of the Egyptian Mediterranean coast).

The linear regression and model results reveal a trend of general decrease of SST with time in the order of about −0.3Oc / 61 years.

The quadratic regression trend of the mean monthly and annual SST has a parabola form.

The parabolas show a decrease in SST in the period from 1948 to 1985 then increasing forward.

The present work may strengthen the suggestion of oscillating sea surface temperature (SST) with time rather than continuous increasing due to the so called global warming.

The cycle of that oscillation must have a period much more than 61 years and may reach to centuries.
