I would suggest going to the met office website and going to the learning section and then try the teachers section.
It has some brilliant explanations, diagrams, interactive etc. .
You can also work through questions etc.
I ask all my students to have a look at it.
Met is my specialist subject (apart from global climatololgy and hadley cells are boring) and i still don't get some of it. Very practical, very theoretical and very unpredictable.
