Example text

Wrap-Up Factors besides latitude have a large effect on the climate of a region. The presence or absence of a nearby ocean will determine if the climate is moderate, as with a maritime climate, or if it is more extreme, as with a continental climate. The temperature of the nearby ocean currents also influence nearby climate. One dramatic example is found in the British Isles, which are much balmier than other locations at similar latitudes, because of the Gulf Stream that flows into the North Atlantic from the equator.

The magnitude of Coriolis deflection depends on the speed of the moving object and its latitude. Faster-moving objects appear to deflect more, as do objects moving near the equator. because the high pressure zone’s location depends on the Earth’s rotation. If the planet did not rotate, there would be two high pressure zones, one at the North Pole and one at the South Pole. Atmospheric circulation would consist of one convection cell in the Northern Hemisphere between the equator and the North Pole and another in the Southern Hemisphere between the equator and the South Pole.

As with atmospheric currents, surface currents turn to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. The currents continue to travel along the continent until they run into an east–west flowing current going in the opposite direction. The result is that surface currents travel in loops called gyres, which rotate clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere. The major surface ocean currents. The five gyres are the North and South Pacific, the North and South Atlantic, and the Indian.
