Which describes both cyclones and anticyclones?

a. Both produce wet, stormy weather.

b. Both are measured by changes in air pressure.

c. Both move air in an upward direction.

d. Both occur at the same time in the same location.

A continental polar air mass forms in

The best answer is B.

A cyclone is a storm or system of wind 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 associated with both cyclones and anticyclones.

Cyclones (commonly known as lows) are generally indicators of rain, clouds and other forms of adverse weather. Anticyclones (commonly referred to as highs) are predictors of fair weather.

Winds in a cyclone blow counterclockwise in the northern hemisphere and clockwise in the southern hemisphere. Winds in an anticyclone blow just the opposite.
