Please Pass The Geography. I Need A Drink.


Well done surviving today's extra long lecture section. Monday should be fun--I plan to do a longer lab with more experiments, the kinds you can observe, touch, hear, even smell and taste. It will be a sensory overload, so prepare accordingly.

Lots of great questions, today. My favorite was, "Why does Indian Summer occur?" We will definitely be discussing global air circulations, soon, but I can tell you it's certainly related to the position of the dominant high pressure zones in the Northern Hemisphere during the autumn months. The one out in the Pacific, called the Hawaiian High, is the main reason we have dry summers and its seasonal shifts, as well as its intensity or weakness, definitely affect when and how our summer shifts into autumn and winter. Its position will also cause changes to the position of the jet stream, which drives the movement of storm systems in the midlatitudes, where you live. More on this, soon!

For now, you can veg out on this mesmerizing Global Wind Map. I think I'm going to project this on the wall at my next party. Very chill. Speaking of chill..

Don't forget to review the slides. And have a great weekend!
