Abstract
The annual cycle curves of heat storage for the Red Sea within different layers as well as the horizontal
distribution of the amplitude of the annual signal are presented and described. The results obtained are based on
monthly objective analyses of data downloaded from the National Oceanographic Data Center NODC, Washington,
D.C. of 2005. The main ambient features obtained are the large annual cycle at 15o
.0 – 20o
.0 N latitude as well as the
strong fluctuations appears in the curves during summer and the lags in the occurrence of maximum heat storage at
the different subsurface layers. The horizontal distribution of the amplitudes of the annual signal are presented for
the upper layers 50-, 100- , 200- and 300- m layers, and their relationship with the water characteristics in the region
and its physical characteristics.
