stability, dew point temp, lapse rate
THE PROPERTIES OF THE ATMOSPHERE, WHICH GAS IS VARIABLE, WHICH 1 IS
GREEN HOUSE GAS
temperature, density,pressure know the formular, know how they relate
know that the atmosphere changes as we move up
the diagram about the composition of the atmosphere in the notes( not the
textbook), whats the difference between the layers of the atmosphere, why
temperature increase and decrease ( everything increase in the temp has to go
why temp increases in certain spot in the atmosphere layers?
Energy: different type of energy tranfers( convecton, conduction, basic eneergy
properties, the difference between conduction, convection and radiation, long-
short wavelength) radiation transfer
conduction: mixing gases
Look at the energy exchange diagram: what is the conductive flux, whats radiation,
DOnt care too much about jump in photon, chemical energy
Know: which wavelength has more energy( hotter object emmits more radiation,
shorter wavelenth; cooler object emmits less radiation, longer wavelength)
-understand basic radiation principles,
-know energy wavelengths
-look careful at the diagrams in this chapter.
-the sun is 16 times more energy
-2 laws are SUPER UPPER IMPORTANT: Stefen law and Kirchoff's law
-Kirchoff's law: the concept of greenhouse gases, there will be green house effect
question in the test, we increase the green house effect by increasing emmitivity
what is biggest greenhouse gas>-> water vapor
know why we have seasons? how many times a year the sun appear direct
overhead in hamilton (0 times)
only 1-2 questions about the seasons.
-what is albedo, what is reflection, absorption, transmit, scatter, -what is a selective absorber?
-the atmospheric greenhouse effect
-what is the atmosphere greenhouse effect, if CO2 in the atmosphere is going up,
how is the temperature going up? ( this is the eg question, use long-short
wavelength, steffan and kirchoff law to ans this)
-greenhouse effect is absorption and re-emmition of heat
-look at those diagrams and understand what going on, dont get caught up with
-Global engery balance
-balancing the budget
HOW SHORT AND LONG WAVE RADIATION HOW INTERACT WITH THE
ATMOSPHERE AND THE MAIN INTERACTION IN THE ATMOSPHERE
-what is the energy balance, radiation balance?=> we have the imbalance in the
radiation balance in the planet.
-R=K-K+L-L is what we get
-R=Q+Q+Q is what we spend
-latent heat is the greatest comsumer globally
atmosphereic pressure and wind what causes wind to move?-> pressure
what causes difference in pressure?-> difference in heating
wind is the response to different tempt and pressure in the planet. the wind is
trying to balance out the pressure.
cold air more dense and warm air is less dense
general decline in pressure as we move.
wind goes from high to low pressure
