The visible earth web site has all sorts of satellite pictures and movies of phenomenon on the earth. If it can be seen from space you will probably find it here.

Career Information: A Guide to Meteorology Resources

If you are interested in a career in meteorology, you may want to check this site out. They have quite a bit of information on various career options. They also have a lot of links to other meteorology resources and articles.

The Ultimate Weather Resource Guide is aimed towards those who are traveling or relocating and wish to investigate the weather and climate of various locations. There are lots of links to useful resources here.

The topics are arranged according to the chapters in Ahrens textbook "Meteorology Today" and the order that I have used those chapters in the introductory meteorology class.

Chapter 1, The Earth and Its Atmosphere

An unusual sunrise! I'm not sure how to categorize this picture. It may be partially due to a mirage, or thin clouds, or some interesting refractive effects. Or it could be all three. But it is really fascinating to look at.
Northern green flash
This is a picture of the transit of Venus across the sun in June 2012 taken near sunrise over the Baltic Sea. However, it also includes a lot of color variation due to atmospheric scattering as well as a faint green flash on the top of the sun.
Another picture of the transit of Venus across the sun in June 2012, at sunrise over the Black Sea this time. It also include color due to atmospheric scattering as well as distortion of the sun due to atmospheric refraction.
