Extratropical Cyclones - Part 1 - Characteristics & Evolution
.
Learning Goals
At the end of this section, you should be able to:
- Using vertical cross sections, contrast warm and cold fronts and occlusions.
- Explain how geostrophic adjustment affects fronts.
- Describe the characteristics of upper-tropospheric fronts
- Compare and contrast dry lines with fronts.
- Synthesize
your knowledge of fronts (including dry lines and gust fronts) with
your knowledge of thunderstorm triggering to explain why some fronts
are favored locations for thunderstorms.
- Draw diagrams showing how fronts change around an evolving cyclone.
- Catalog favored cyclogenesis regions, and explain why they are favored.
- Explain why cyclones can intensify in spite counteracting effect of boundary-layer winds.
- Diagnose cyclone location, movement, and evolutionary stage from satellite imagery.
- Recognize cyclones in upper-level isobaric charts as well as surface charts.
- Form a picture in your mind of the 3-D structure of extratropical cyclones, especially of the tilting of the low center with height.
