CE Enhancement Curve
(this 22-image Java animation sequence will take a minute or two to load...)
The CE enhancement curve is designed for general use at higher latitudes, and delineates the active precipitating segments of winter weather systems. The blue region highlights the typical cloud glaciation level (-28 to -39 C). The colder enhancement levels are: -40 to -49 (reds), -50 to -59 (brown), -60 to -69 (black).
