Geology 1350 Lecture 4 Outline of Last Lecture I. AtmoshpereII. PressureIII. Phases in Atmosphere (pauses)Outline of Current Lecture I. EnergyII. Heat ConductorsCurrent LectureEnergy- potential energy, it goes upKinetic energy- ½(mass)(velocity)^2Internal energy-potential plus kinetic energyCommonly used scales-Fahrenheit(180 parts -32f-212f),Celsius (100 parts-0c-100c),kelvin (abs zero)Kelvin in terms of velocity is 0 temperature decreases when Celsius thermometer goes upMeasures 2 meters above the surfaceGradient is the distance between two particlesMeaning you would need to see a fast temperature changeAir is a poor heat conductorPhotolesis-in stratosphereWind will be zero at the surfaceHeat transfer is due to temperature differencesWater has higher heat capacity (depends on specific heat) than dry airThese 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.Latent heat- (important source of atmospheric energy) hidden heat until changes occur (water vapor is an important medium in order for latent heat to occur)Conduction-creates heat, conducts heat, occurs on surface, air is poor conductor of heat in atmosphereConvection- transports and transfers heat through air, vertical motionAdvection-wind, horizontal
