GGR100H1 Lecture Notes - Lecture 2: Ozone Layer, Polar Easterlies, Atmospheric Circulation
Document Summary
Wavelength: the spatial period of a sinusoidal wave. 5% reaches earth and water and gets bounced back. Red light = longer wavelength than purple light. Spins at the n and s poles. Combine earth"s orbit, tilt, rotation and wobble. Large scale theory of long term climate change on our planet. Layer of gases surrounding our planet held to us by gravity. Air is a fluid it flows. In between the troposphere and stratosphere is the tropopause. Where the ozone layer is most in lower stratosphere. Has a warm to cold temperature stratification. Protects against harmful uv-b and uv-c rays. In the 90s, governments came together to ban cfcs because they made holes in the ozone layers. Highest altitude in which airplanes will travel. Pattern defined by 3 different cells: polar cell north and southern poles, ferrel mid-continental cells, hadley cells equator to 30 degrees n and s, circulating patterns meet at the itcz.
