An Extratropical Cyclone Atlas: A Tool for Illustrating Cyclone Structure and Evolution Characteristics

The cold conveyor belt is a flow of air characterized by lower temperatures that flows rearward, relative to the advancing system and ahead of the warm front, and ascends to form the lower part of the cloud head (Fig. 5a). Some examples of how this atlas could be used for both educational and resear...

Description
Summary:The cold conveyor belt is a flow of air characterized by lower temperatures that flows rearward, relative to the advancing system and ahead of the warm front, and ascends to form the lower part of the cloud head (Fig. 5a). Some examples of how this atlas could be used for both educational and research purposes include * providing quantitative values for atmospheric variables associated with "typical" extratropical cyclones (e.g., frontal temperature gradients, jet streak wind speeds, ascent and descent rates); * introducing students to the concept of systemrelative winds; * teaching students about flow along isentropic surfaces; * teaching students how to position surface fronts; and * comparison of average fields with case study analysis.
