GLY 102 Lecture Notes - Lecture 2: 30Th Parallel North, Cumulonimbus Incus, Lapse Rate
Document Summary
Amount of temp change per unit of height in the troposphere known as the lapse rate. Influences on temperature: adiabatic cooling: air cools 6-10 degrees c per km in altitude, due to pressure drop (inverse: higher pressure warms air, solar heating: above the tropopause, solar radiation directly heats the air. Electromagnetic energy absorbed in the stratosphere and troposphere. Troposhpere: temperature decreases with height adiabatic cooling, lapse rate: 3. 6 degrees fahrenheit/ 1000ft or 10 degrees. Atmosphere gases can be variable: the concentration of some atmospheric gasses varies through time, usually in tiny amounts, examples: water vapor - . 25%: weather. Ozone (o3) 0. 01%; protection: ozone whole little to do with climate change but protection. Low exchange rate: low input, low output: long residence time. High exchange rate: high input, high output: short residence time. Residence time equation: t = (mass of the reservoir in kg) / (flux in kg per second) Example: tsp delivering water at 4oz per second.
