ANSWER: Only 2
- An anticyclone (that is, opposite to a cyclone) is a weather phenomenon that is a large-scale circulation of winds around a central region of high atmospheric pressure.
- It moves clockwise in the Northern Hemisphere, anti-clockwise in the Southern Hemisphere.
- The strongest anticyclones occur over snow-covered portions of Asia and North America in the winter when clear, dry air masses cool from a loss of infrared radiation, while little sunlight is absorbed to offset that infrared cooling.
