NOAA color enhanced weather maps are used by meteorologists to aid them with
satellite interpretation. The weather map color's enable a meteorologist to
easily and
quickly see features which are of special interest. Usually they
look for high clouds or areas with a large amount of water vapor.
In infrared (IR) weather maps, cold clouds are high clouds, so the colors
typically highlight the colder regions. In a water vapor weather map, white
areas indicate moisture and dark areas indicate little or no moisture, so
the colors typically highlight areas with large amounts of moisture.
