Following last year’s earth day post I decided to do a short reprise of a few images of earth. Above is the first image sent back by the GOES-11 satellite on May 17th, 2000. You may not be familiar with the GOES satellites directly, but this type of satellite provides all of the visible cloud and water vapor imagery that gets shown during the weather section of the news. One of the most amazing things I notice in this image is the strong linear feature of clouds just north of the equator. This is called the Inter Tropical Convergence Zone (ITCZ) and is where the air from the northern and southern hemispheres meet and ascend. We write equations about it, talk about it in theory, but there it is!
For more about Larsen B see “Fragment of its Former Shelf” from NASA earth observatory.
Look at the Amazon and Congo rainforests for the orange pulse of the daily cycle in precipitation! There are even hurricanes! Last year I talked about how the complexity and heterogeneity of the earth’s surface makes me think it is impossible to write down in the form of equations. This year I’ll go with optimism. These results look like a real atmosphere. Amazing!
(I have limited video embedding skills (or desire to gain such skills) so please bear with me for the screen shot and link) To see more months or view the entire year go to the Community Climate Model.
People often ask me if I get depressed studying global warming, but in truth, I don’t. I guess I feel good about the fact that I’m trying to do something about it in the best way I know how. I hope you can all do the same. Happy earth day everyone!
