In that case then I think it's all correct.

Did the Climate Cookbook say what should happen in the tropics in summer? I can't remember whether I had a band of high pressure over both air and land like that, I'll have to go check the files I made again...
If it does, I haven't managed to spot it A lot of what he writes about seems to apply predominantly to land-masses with central latitudes of around 30 degrees north or south of the equator, which obviously gets more problematic when you want to look elsewhere.

However, a link provided in the Cookbook contains these two images of Earth:





So, what seems to be happening, on Earth at least, is that in July there is a continuous band of generally high pressure south of the equator and then another one north of the equator in January both at around 30 degrees N or S. However, it also suggests that even within these continuous bands, we find differences in pressure, dropping off between the centres of high pressure, which thinking about it makes sense
