Document Summary

Lecture 3: high concentrations of water vapour, 4%. Every 100 molecules 4 will be water vapour. In contrast to the desert, they have low water vapour: water vapour is a naturally occurring greenhouse gas, water vapour is one of the exceptions to homogeneity of atmosphere. Negligible turbulence: the layers of these gases diffuse gradually. Transitions: no defi(cid:374)ite li(cid:373)it to earth"s at(cid:373)osphere, what (cid:449)e also fi(cid:374)d i(cid:374) earth"s atmosphere are aerosols.
