Use the following terms to fill in the blanks for questions a & b

Low, High, inward, outward, clockwise

Counter-clockwise

a. In cyclones, ________ air pressure occurs in the center of the cell. Surface winds move ________. The surface winds will rotate _________ in the northern hemisphere and ___________ in the southern hemisphere.

b. In anticyclones, ______ air pressure occurs in the center of the cell. Surface winds move ______. The surface winds will rotate _________ in the northern hemisphere and ___________ in the southern hemisphere.

Explanation / Answer

a. In cyclones, Low air pressure occurs in the center of the cell. Surface winds move outward.

The surface winds will rotate counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.

b. In anticyclones,High air pressure occurs in the center of the cell. Surface winds move inward.

The surface winds will rotate clockwise in the northern hemisphere and Counter-clockwise in the southern hemisphere.

A cyclone is a storm or system of winds that rotates around a center of low atmospheric pressure. An anticyclone is a system of winds that rotates around a center of high atmospheric pressure. Distinctive weather patterns tend to be associated with both cyclones and anticyclones. Cyclones (commonly known as lows) generally are indicators of rain, clouds, and other forms of bad weather. Anticyclones (commonly known as highs) are predictors of fair weather.

An anticyclone (that is, opposite to a cyclone) is a weather phenomenon defined by the United States National Weather Service's glossary as a large-scale circulation of winds around a central region of high atmospheric pressure, clockwise in the Northern Hemisphere, counterclockwise in the Southern Hemisphere. Effects of surface-based anticyclones include clearing skies as well as cooler, drier air. Fog can also form overnight within a region of higher pressure. Anticyclones aloft can form within warm core lows such as tropical cyclones, due to descending cool air from the backside of upper troughs such as polar highs, or from large scale sinking such as the subtropical ridge.
