As su_liam points out, hot air rising causes low pressure regions, with the air rising when the land is warm in the summer, while high pressure areas form when the land is cooler in the winter.
In winter (in the northern hemisphere, since that's what Bricka deals with
), the cooling of the land creates a high-pressure area over the interior
while in summer (northern hemisphere again
) the land warms to create a low-pressure area
(the southern hemisphere thus follows the opposite pattern
Now, back to the main point of the question, Bricka tends only to discuss pressures and wind directions in and around the STHZ, rather than in the PF or the ITCZ, so I'm going to assume that either a) there isn't much of a difference in those areas between the summer and winter months and that the major differences occur in the STHZ or that b) Bricka's information on the subject is lacking.
Since I can't be sure which conclusion is correct, I don't feel confident carrying on this section of my work without advice from those more knowledgeable than myself.
