ATM 103 Lecture Notes - Lecture 20: Cryosphere, Geosphere, U.S. Route 3
Document Summary
3 regions: how cold the winters get is the difference. Eastern us the difference is how cold the winter gets. The climate system involves exchanges of energy and moisture among five spheres. Atmosphere: mostly within 20 miles of surface, protects, where weather occurs! Cryosphere: the earth"s surface that is solid water. There are no equilibrium climate, it always change. Tectonic plates move very slowly and produce very gradual changes. Why having change of the location of the continents can effect global temperature. This material filters out solar radiation (reflection) It also lowers the temperature in the troposphere. The mount st. helens eruption lowered the temperature 0. 1 c. El chichon, in 1982, lowered the temperature 0. 3-0. 5c. Mount pinatubo, in 1991, lowered temperature 0. 5c. The milankovitch mathematical model is based on several elements. Variations in shape (eccentricity) of earth"s orbit about the sun. Changes in obliquity - that is, changes in the angle of axis.
