The GOES-13 satellite’s infrared water vapor imagery illustrates just how dynamic and beautiful the atmosphere can be when looking at it from 22,000 miles away. Shown here are the last four days of imagery (September 23-27, 2011). This mid-latitude cyclone has spiraled seemingly in the same location for 96 hours, also called a retro-grade low. The system should decay over the next day, bringing much needed relief to the cloud-beleaguered residents on the ground throughout the Midwest. The GOES water vapor imagery allows us to see not only the moist air in the atmosphere, but also the dry air (clear areas), some associated with the path of the jet stream. |
