This was more for asking people's thoughts and personal ideas as to what they think is causing it. I should probably change the post from question.
I personally think the clouds are, for some reason, just pooling towards the equator and leaving very sparse overcast at the poles, the south pole especially.Yes. It is unexpected, but it is because a different mechanism controls the temperature.
It is strange to us, because we expect nearer the Sun to be warmer.
