NOTE: We've guessed that you're not using a client that supports colored tables and have tried to compensate. Low graphics mode looks much better on clients that do... we recommend switching to Netscape 3.0 or Microsoft Internet Explorer.

700 mb Temps and Heights

Reference Weather Map

Current Weather Map

This panel shows the 700 mb field for geopotential height, and temperature. 700 mb charts depict conditions in the middle troposphere (roughly 3000 meters). This is also referred to as the steering level, since most weather systems are "steered" by the winds at this level.

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.
