MET
A little off the beaten track but;
MET seems to be a bit of a headache for students (well, most of us). I have found the met-office website really good for getting info on nearly everything weather related, in relation to learning.
They have a section for students and teachers for learning and teaching the subject. You can type in pretty much anything and it will have a section on it.
Came in handy when I was asked about frontolysis (which i knew about) and frontogenesis (which stumped me a bit).
