Question

The model shows global atmospheric circulation. Identify the wind directions that are correct. 1) Clockwise around a low-pressure area and counterclockwise around a high-pressure area. 2) From the east to west at the Equator. 3) From the west to east at the Tropic of Cancer. 4) From the east to west at the Tropic of Capricorn. 5) From the east to west near the Arctic Circle and the Antarctic Circle.

Answer 1

In global atmospheric circulation, wind directions are clockwise around a low-pressure area and counterclockwise around a high-pressure area. Near the Arctic and Antarctic Circles, the prevailing winds flow from east to west.

The options (A) and (B) are correct.

The wind directions that are correct in global atmospheric circulation are:

1. Clockwise around a low-pressure area and counterclockwise around a high-pressure area.
2. From the east to west near the Arctic Circle and the Antarctic Circle.

The Coriolis force causes these wind directions. In the Northern Hemisphere, low-pressure zones have counterclockwise circulation and high-pressure zones have clockwise circulation. Near the Arctic and Antarctic Circles, the prevailing winds flow from east to west.
