The interaction of the ocean with the atmosphere and the land


1. How is heat and moisture exchanged between the ocean and the land?

The waters of the World Ocean interact with the air of the atmosphere and through the transfer of air masses affect the temperature and humidity on the land surface.

2. What is the difference between air masses formed over land and ocean?

Water, unlike a solid surface of land, is heated for a long time and gives heat for a long time.

In winter, warm and humid marine air masses, entering the surface of the land, significantly increase the temperature of the air and promote precipitation and increase in humidity. Continental air masses, on the contrary, are cold and dry in winter, and under their influence the temperature on the coasts of the continents decreases, and the amount of precipitation decreases.

In the summer, the incoming sea air masses contribute to a certain decrease in temperature on the coasts and an increase in the amount of precipitation. The arrival of dry and hot continental tropical air masses on the coasts increases the temperature and dryness of the air, making the summer more hot and dry. Warm and cold ocean currents, provided they pass along the coast of the continents, increase the influence of the ocean on the temperature and humidity of the land. Warms help to increase the temperature and increase the amount of precipitation, and cold – on the contrary.
