The Marine Effect On Gulf Region Climate: The case of Upwelling &The Tropical Easterly Jet Stream

Prof. Dr. Awad Ibrahim Abdel-Rahman El-H


The main thesis of this research paper is that both upwelling process and Eastern Jet Stream are important climate factors in the study area: Any change in their behaviours leads to climate change. Also, it is to say that a compound effect of both Up-welling and The Tropical Easterly Jet Stream (TEJ) is the main cause of aridity in the Gulf region and its vicinity. Sea water upwelling is one of the most important of these two factors that affect rainfall in the coasts of the Arabian Sea. Such a phenomenon brings all physical, chemical and biological changes to the sea water in the area. Temperature change, that is a prominent modification caused by water upwelling, affects water evaporation. The Tropical Easterly Jet Stream (TEJ) is also another main factor of aridity in the area. In an other instance, the two phenomena work together to prevent both the Monsoon south easterly and the south westerly winds from accomplishing their function in causing rainfall in the region. The humid Monsoon Winds have been diverted to be parallel to the coast carrying out no positive effect on rainfall in the area.
