The Atmosphere
Wind Stress & Turbulence
Sea Ice Forms at polar latitudes Salt molecules excluded from ice latticework
Sea Ice Floes Ridges & hummocks Fast ice
Sea Ice
Arctic Semi-enclosed 2-3 m 3% decrease per
decade Antarctic
Open 1-2 m
Ice-Albedo Positive Feedback Loop How melting ice causes more ice to melt!
Effects of Rotation Coriolis Effect
Coriolis Effect Coriolis effect is the apparent deflection of
moving objects to the right in the Northern Hemisphere and to the left in the Southern Hemisphere
The deflection is caused by the differential speed of rotation between Earth’s equator and polar regions, relative to an object moving across the Earth’s surface.
Centrifugal force
