This panel shows the 700 mb field for geopotential height, and temperature. Geopotential height approximates the actual height of a pressure surface above mean sea-level and is represented by the solid white contours. The geopotential height field is given in meters with an interval of 30 meters between height lines. The locations of surface cyclones and anticyclones hold similar positions in the 700 mb geopotential height field.
Temperature is represented by contour lines which are labeled.
Temperatures are given in degrees Celsius with an interval of 5 degrees Celsius between temperature contours, also called isotherms. 700 mb vert velocity Terms for using data resources. Credits and Acknowledgments for WW2010.
