CHICAGO REFLECTED IN LAKE MICHIGAN FROM AN AIRPLANE

“I was flying home to Chicago from a business trip recently. It was a cloudy day, late in the afternoon. We were flying eastbound, made a pass by O’Hare International Airport, then made a sweeping 180-degree left turn over Lake Michigan for our final westward approach into the airport. I looked down and through a narrow break in the clouds, I saw the shadow of the Chicago skyline projecting onto the lake. Oddly enough, I am a very frequent flyer and almost always sit in an aisle seat, but on this flight there were only window seats available.”

Gravity Waves

(GOETHE UNIVERSITY FRANKFURT) Gravity waves form in the atmosphere as a result of destabilizing processes, for example at weather fronts, during storms or when air masses stroke over mountain ranges. They can occasionally be seen in the sky as bands of cloud. For weather forecast and climate models, however, they are mostly ‘invisible’ due to their short wavelength.
