Well, I finally got around to doing the winds and pressures.

The purple band is the ITCZ, blue represents low pressure, and yellow high pressure (with orange being a high pressure center).

Doing a basic Köppen-Geiger map will be easy enough, though I'm not really willing to go through the entire process of Azelor's tutorial, so I'll probably just make educated guesses regarding the climate, rather than making separate temperature and precipitation maps. Still, even a basic map should give a pretty good idea of what the climate is like in each region, and should be quite sufficient if you don't need a super-detailed climate map. That said, you could also ask Azelor if he wants to take your map through the tutorial process, it's only a single continent so it's not that much work.
