Surface Contours: surface maps

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.

Surface Contours surface maps

The various contours available for surface images include:

isobars (lines of constant pressure)
isotherms (lines of constant temperature)
isodrosotherms (lines of constant dew point temperature)

This section has been designed to explain what each feature represents and how to interpret them on weather maps.

The Following Options Are Available:
