Advice on teaching the ITCZ

First from Val Vannet:
"I reckon the ITCZ is one of those topics where 'old technology' works best. You just can't beat two sheets of acetate on an OHP! Get your base map on one and draw the ITCZ and the converging air masses/winds on the other and then move it 'with the seasons'.
I usually get a climate graph for somewhere in Northern Nigeria at the ready, plot that location on my base map and as I shift the ICTZ, point out the corelation between the prevailing air mass and precipitation. This usually works!"

and from "Blue Square Thing":
"With the ITCZ I find it helps them to have a A3 sheet with 4 maps on and to be able to locate it in Dec, Mar, Jun and Sep - and then to add the Sub-Tropical High and so on - I use Africa essentially as it makes more sense later when I come back to ecoclines - and in Edexcel B I always make sure that I do grasslands rather than forests as the content doubles up nicely."
