Document Summary

The poleward heat transport surplus of energy close to the latitudes, more incoming radiation: red line- energy lost back to space. Latent heat is indication of how much water vapour, more energy needed to vaporize the water. Energy is needed to break the bonds in the water molecules. When water is changing states we can see the latent heat released is being absorbed. Actual quantity of water vapour in air. Sh= mass of water vapour (g)/ mass of total air (kg) A(cid:373)ou(cid:374)t of (cid:449)ater (cid:448)apour prese(cid:374)t does(cid:374)"t change when water molecules expand (evaporate) Maximum amount of h2ov (ie. sh) that an air parcel can contain at any given time. Cold days- no snowfall, amount of water vapour is low. Over line= over saturated, condensation will start to take place, too much water vapour- generate an equilibrium. Density of gas cannot be increased above a certain level. Change of phase once limit is reached.
