DRYLINES, GUST FRONTS, COASTAL FRONTS, AND TOPOGRAPHICALLY INDUCED FRONTS - IMPORTANT CONCEPTS AND QUESTION
Drylines:
- How is a dryline defined? Where would it be located on a surface analysis?
- What is the significance of the dryline?
- describe the eastward movement of the dryline in terms of boundary layer mixing
- Discuss the two mechanisms that may be responsible for the westward motion of the dryline later in the day.
- Discuss the across-frontal structure of the dyline.
- Discuss the along-line structure of the dryline.
- What is the inland sea-breeze effect? How does it collapse the across frontal scale?
- Can multiple drylines exist simultaneously?
Gust fronts:
- Draw a diagram of a density current and indicate the location of the noes, head, body, and turbulent wake. How much deeper is the head relative to the body?
- What are typical propagation speeds, depths, and temperature drops for gust fronts?
- Do they tend to be sharp or diffuse boundaries?
- How do common weather variables change during passage at the surface?
- Why does the pressure rise before the front passes overhead? Why does it continue to rise after passage?
- How are gust fronts similar to density currents?
- Does might the protruding nose lead to cleft/lobe instability?
Coastal Fronts:
- How/why do they form?
- Typical weather on the west and east sides?
- Are they sharp or diffuse?
- How are coastal fronts similar to density currents?
Denver Convergence Zone:
- How does it form?
- What does the ambient flow direction have to be in order for it to form?
- What are misocylones?
