Why does cool weather bring clear skies.......

So, you want more detail?

The speed at which air pressure increases will determine the type of weather an area can expect. If the air pressure rises very quickly, the calm weather and clear skies will generally be over as quickly as they came. An abrupt rise in pressure can indicate a short-lived high pressure zone with a stormy low pressure zone behind it. That means you can expect clear skies followed by a storm. (Think: What goes up, must come down) If the rise in pressure is more gradual, a persistent period of calm may be seen for several days.

It is all a repetitive cycle.

Thanks for the additional info, Siobain - always great to learn and grow - but I am looking more for the actual processes that connect cool air with clear skies.

No takers?

Answer tomorrow ...

I've misplaced my book that explains it all so well. Hence the delay. This quiz has been held up enough. Anyone can post a Q and I'll get back to answering the last one when the book is found.

So next one: What does this map show? Can you guess?

That's got to be average temperature

Sorry Tom ... NO

Dark around the equator where the most trees/forests are... And desert almost the same as the sea...

HMMM, Bishop, it occurs more over land than ocean or near the poles because daily sunshine heats up the land surface faster than the ocean.
More hot air leads to ???

Is that cloud cover?
