How do the prevailing westerly winds and the North-Atlantic drift affect the weather in Western Europe?
Europe is warmer than it should be given its lattitude because of the N.A.D. The North Atlantic Drift is an underwater current that forces warm water from the Carribean, east all the way to the Western end of Eurasia. In addition, the N.A.D. brings with it prevailing winds which lose most of its heat when they cross Portugual. Another example of currency is Lake Michigan. Since water changes temperature slowly, the closer you are to the lake in the summer the cooler it is and the closer you are to the lake in the winter the warmer it is. Therefore, Europe is warmer than it should be due to climactic changes brought about by the N.A.D.
