As predicted, Gaston has emerged from from the ITCZ as a named tropical storm in the eastern Atlantic. Unlike Fiona, Gaston will reach hurricane status, and in fact, there is a pretty good chance that Gaston will be a major hurricane. What matters, of course, is where it goes. In any event, formation of a hurricane and nearing land will not happen until Labor Day or later.
Meanwhile, Earl, which during the night Thursday and early morning Friday will be turning with 100 knot winds off the coast of the Carolinas, is getting some special attention from NASA. Here’s a picture NASA published just a few minutes ago:
AIRS infrared image of Hurricane Earl on Sept. 1, 2010, shows the temperature of Earl’s cloud tops or the surface of Earth in cloud-free regions. The coldest cloud-top temperatures appear in purple, indicating towering cold clouds and heavy precipitation. Image credit: NASA/JPL-Caltech
In case you wanted to see wind speed and vector data from within the hurricane, we have that for you as well:
MISR image of Hurricane Earl captured on Aug. 30, 2010. The left panel of the image extends about 1,110 kilometers (690 miles) in the north-south direction and 380 kilometers (236 miles) in the east-west direction. Earl’s wind speeds are shown in the right panel. The lengths of the arrows indicate the wind speeds, and their orientation shows wind direction. The altitude of a given wind vector is shown in color.

And here is yet another image of Earl:

And, the coolest thing of all is this animation:
Animation depicts a vertical cross-section of Hurricane Earl as seen by NASA’s CloudSat satellite on Aug. 31, 2010. CloudSat captured Earl’s intense cumulonimbus clouds and eye, along with cloud-free regions. The storm’s most intense convection and precipitation are shown in shades of orange and red.

I write about science, science policy, science education, politics and science, politics, and technology.
The science is mostly climate change, life science, evolution, and science education. The science policy and politics is mostly about climate change and the evolution-creationism false controversy. The technology is mostly about Linux, regular normal person computer use, kids programming, and now and then, household items.
As an Anthropologist and Africanist, I often write about those topics as well.
Usually, I write about one or two topics for a while then shift to something different. This is not systematic, and has to do with context and external forces such as: Is this a presidential election year? Are we having an El Nino? Is there a fight going on somewhere about teaching creationism in a public school? Did I just get a cool new robot toy? Like that.
So, if you don't find the most recent few posts interesting, have a look at the topics below. But, of course, chances are you got here with a Google search and you'll never read this "about" thing.
