Hi,
I'm currently cooking an idea for a science fiction story (oh boy, imagined science, I know) involving a world where the climate changes drastically seasonally. As a simplified example, a planet with a wet season and a dry season, and here's the trick: while one hemisphere is suffering extensive drought, the other is living large on plenty of rain.
Problem is, I've only taken freshman Geology in college, and I don't know how this would come about. I know enough to know that the answer to this question probably involves wind conditions, but not enough to come up with a reasonable explanation for the unusual weather.
I was wondering if anybody could, at the very least, point me to a book that discusses issues such as these, or even better, explain some possible scenarios (in layman's terms) that might bring this situation about?
Thanks.
