For the globe as a whole, the ocean is the great regulator of temperatures. It has been de-scribed as a "sayings bank for solar energy, .receiving deposits in seasons of want. “Without the/ ocean, our worm would be visited by unthinkably harsh extremes of Temperatures. For the water that covers three-fourths of the earth's surface with an enveloping mantle is substance of remarkable qualities. It is an excellent absorber and radiator of heat. Because of its enormous heat capacity, the ocean can absorb a great deal of heat from the sun without becoming what we would consider "hot" , or it can lose much of its heat without becoming "cold".

Replica Watches Through the agency of ocean currents, heat and cold may be distributed over thousands of miles. It is possible to follow the course of a mass of warm water that 'originates in the trade wind belt of the Southern Hemisphere and remains recognizable for a year and a half through a course of more than 7,000 miles. This redistributing function of the ocean tends to make up for the uneven beating of the globe by the sun. As it is, ocean currents carry hot equatorial water toward the poles and return cold water equator ward by such surface drifts as the Labrador Current and Yoshiro, and even more importantly , by deep currents. The redistribution of heat for the whole earth is accomplished about half by the ocean currents, and half by the winds. Replica Watches At that thin interface between the ocean of water and the ocean of overlying air, lying as they do in direct contact over by far the greater part of the earth, there are continuous interactions of tremendous importance.

Replica Rolex Watches The atmosphere warms or cools the ocean. It receives vapors through evaporation, leaving, most of the salts in the sea and so increasing the salinity of the water. With the changing weight: of that whole mass of air that envelops the earth, the atmosphere brings variable pressure to bear on the surface of the sea, which is depressed under areas of high pressure and springs up in compensation under the atmospheric lows. With the moving force of the winds, the air grips the surface of the ocean and raises it into waves, drives the currents onward, lowers sea level on lee; shores, and raises it on windward shores.#;But even more does the ocean dominate the air. Its effect on the temperature and humidity of: the atmosphere is far greater than the small transfer of heat from air to sea. It takes 3,000 times as much heat to warm a given volume of water 17t as to warm an equal volume of air by the same amount. The heat lost by a cubic meter of water on cooling it would raise the temperature of 3,000 cubic meters of air by the same amount. Or to use another example, a layer of water a meter deep, on cooling it could warm a layer of air 33 meters thick by 101. The temperature of the air is intimately related to atmospheric pressure. Where the air is cold, pressure tends to be high; warm air favors low pressures. The transfer of heat between ocean and air therefore alters the belts of high and low pressure; this profoundly affects the direction and strength of the winds and directs the storms on their paths.

Replica Rolex WatchesThere are six more or less permanent centers of high pressure over the oceans, three in each hemi-sphere. Not only do these areas play a controlling part in the climate of surrounding lands, but they affect the whole world because they are the birthplaces of most of the dominant winds of the globe. The trade winds originate in high-pressure belts of the Northern and Southern Hemisphere. Over all the vast extent of ocean across which they blow, these great winds retain their identity; it is only over the continents that they become interrupted, confused, and modified.
