Isobars


www.silweather.com/ mapindx.html

An isobar is a line drawn on a weather map connecting areas of equal pressure. This particular map has the isobars overlaying satellite imagery. This particular map was done by NOAA, the National Oceanic and Atmospheric Administration. NOAA not only provides atmospheric information they also do such things as tracking the migration of whales. I'm sure this is not the extent of their duties, but I thought it was interesting.
