Atmosphere in Motion (Earth Science Class) Essay

Atmosphere in Motion (Earth Science Class) - Essay Example The advantage of using the aneroid barometer is that the readings are more accurate and that a week’s worth of data is recorded with each cylinder. 2- Explain how the pressure gradient force, Coriolis Effect, and friction affect wind Coriolis Effect: Wind moves to the right of the direction of the body motion for counterclockwise rotation of the frame of reference, or to the left for a clockwise rotation; this is called the Coriolis Effect. The pressure gradient force and the Coriolis Effect work together to channel the air flow. The pressure gradient force causes air to start moving across the isobars; as soon as the air starts to move, the Coriolis Effect acts at right angles to this motion. Friction is an additional factor that has a significant effect on the wind, changing both its velocity and its direction. Friction causes wind to decrease, thus decelerating the Coriolis Effect. This makes the wind corkscrew away from the high pressure centers and into the low pressure c enters in the Northern Hemisphere. It has the contrary effect in the Southern Hemisphere. 3- Discuss the movements of air and weather patterns associated with cyclones and anticyclones. A wind in a cyclone blows counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
