The differences between the light side of a tidal locked planet and the earth's poles are many.

First and foremost, the poles are getting light all day for 1/2 the year. The second half is dark, and cold. The light side of *this* planet is *always* light, and warmed by the sun.

The poles receive (even in their summer) indirect sunlight, the light side of this planet receives direct sunlight.

The ice already at the poles from prior circumstances (Ice Age, anyone?) has a cooling effect as well. That *keeps* the poles cool, even when they would normally warm under the light. This planet doesn't seem to have had the same unique series of events, and has, therefore, no huge ice masses in the area you're comparing to the polar caps.

I'd imagine that there would be no ice at all, well into the "dark" side of the planet, especially with such a huge landmass, which also tends to warm things up.

And there would be high and low pressure zones on EACH side, because sunlight/heat is not the only thing that affects pressure.

@ Pixie: Sounded dead-on from what little I did bother to check.
