Here's the first, The Urban Heat Island Explained.
The Weather Channel meteorologist Mark Elliot explains why cities are usually warmer than the suburbs.This video concentrates on exactly the aspects of the urban heat island as an example of a microclimate that I emphasize in my lectures--the causes, the effects on nighttime temperatures, the increase in thunderstorms, and the differences between the temperatures of the city and the surrounding suburbs and countryside. My only complaint is the low resolution, which won't look good on a big screen.
I may or may not show the second video, Reducing the Urban Heat Island, because climate is usually the last lecture, and I tend to run out of time, but I'll see.
Researchers are working to find ways to reduce what is known as Urban Heat Island. That happens when a metropolitan area is significantly warmer than it's suburbs due to human causes.On the one hand, this has the same low resolution as the previous video, which makes it less likely for me to use it. On the other hand, it does a good job of bringing in the esthetics of urban areas as well as connecting heat to ozone production. Since I cover air pollution in the same lecture as I do microclimates, that makes this video worth showing to my classes. Here's to hoping I make the time to do so.
