Read About Sea
The Red Sea is between arid land, desert and semi-desert. Reef systems are best developed along the Red Sea, mainly because of its greater depths and a pattern of efficient water circulation. The means of water exchange the water of the Red Sea to the Arabian Sea, the Indian Ocean through the Gulf of Aden. These physical factors reduce the effect of high salinity caused by evaporation in the north and relatively hot water in the south.
The climate of the Red Sea is the result of two monsoon seasons; northeast monsoon and southwest monsoon. Monsoon winds occur due to differential heating between land and sea. Very high surface temperatures and high salinities makes this one of the hottest and saltiest sea water bodies in the world. The average temperature of the surface waters of the Red Sea during the summer is about 26 ° C (79 ° F) in the north and 30 ° C (86 ° F) in the south, with only about 2 ° C (3.6 ° F) Changes during the winter months. The overall average water temperature is 22 ° C (72 ° F). The temperature and visibility remain good to around 200 m (656 ft). The sea is known for its strong winds and unpredictable local currents.
Rainfall over the Red Sea and its coasts is extremely low, averaging 0.06 m (2.36 inches) per year. Rain is mostly short showers, often with thunderstorms and occasionally with dust storms. The low rainfall and no major source of fresh water to the Red Sea result in the excess evaporation of up to 205 cm (81 inches) per year and high salinity with minimal seasonal variation. A recent underwater expedition of the Red Sea offshore from Sudan and Eritrea [18] found surface water temperatures 28 ° C in winter and up to 34 ° C in the summer, but despite the extreme heat the coral was healthy with much fish life with very little sign of coral bleaching, with only 9% loyana Thalassomonas infected by the agent "white plague". Favia coral favus not harbor a virus, BA3, which kills T.loyana. [19] There are plans to use samples of these corals algae diners apparently heat-adapted to salvage bleached coral elsewhere.
