MTEOR 206 1st Edition Lecture 3 Outline of Last Lecture I. CO2 CycleII. Station ModelOutline of Current Lecture I. Properties of The AtmosphereCurrent LectureI. Properties of The Atmospherea. Temperature i. Physics definition: the measure of the average speed of atoms and moleculesii. The hotter the object, the faster the motions. The faster the motion, the hotter the objectiii. Measured in Kelvin, Celsius, and Fahrenheitiv. Scale Conversion1. F = [(9/5) x C] + 322. C = (5/9) x (F – 32)3. K = C + 273.154. Quick estimatesa. For every 5 degrees Celsius change, 9 degrees F changeb. For every 10 degrees Celsius change, 18 degrees F changev. Troposphere: the area of the atmosphere where we reside1. Decreasing temperature with heightvi. Stratosphere warms due to the amount of ozone because energy absorption results in an increase in temperaturevii. Lapse rate: rate at which air temperature decreases with height1. 6.5 degrees Celsius for every 1000 meter rise in elevation2. 3.6 degrees Fahrenheit for every 1000 foot rise in elevationviii. Temperature inversion: region of increasing temperature with heightb. Pressure i. Physics definition: force/area (force over area)1. Expressed in:a. Lbs/inches squaredb. Pascalsc. Hectopascal = 1 mbThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.d. Millibars (used in meteorology)ii. Meteorology definition: weight of the column of air above youiii. Pressure decreases with heightiv. Surface pressure: weight of column of air above the surfacev. Pressure decreases very quickly close to the surface (2 reasons why)1. Atmosphere is compressible2. The heavier parts of the atmosphere are packed tight to the
