Climatological trend of air temperature anomalies in the South Eastern Mediterranean Sea

Abstract EN

The issue of the climate change has become one of the most interested topics.

In this paper a fair trial is discussed to get a reasonable answer to the question : can the global warming be considered as an absolute continuous behavior? , taking the southeastern Mediterranean Sea as a case study.

It depends on the analysis of continuous air temperature records (33 years) off the Egyptian Mediterranean coast.

The linear regression trend of the monthly air temperature anomaly (MATA) shows a general decrease of 0.4116o C 33 / years (-0.0125o C / year).

The quadratic regression trend has a parabola form with a general decrease from 1958 to 1981 followed by a forward increase.

Checking variations in the air temperature and hydrography together with the phenomenon of the River Nile droughts shows that the 70-year cycle appears to be one of the most affective contributors in the climatic change.

This does not affect only the area of investigation for the present work but seems to have a worldwide impact (River Nile droughts and global fish production).

It may be anticipated that the present warm part of climate cycle ends by 2016 to start a new cold part of climate cycle.
