Cold Fronts

• Zone/boundary between warmer, more moist, unstable air (usually mT) being replaced by colder, drier, more stable air (usually cP).
• Location of cold front:
  • leading edge of sharp temperature change
  • moisture content (dew point) changes dramatically
  • wind shift (direction and speed)
  • pressure trough (pressure tendency is useful!!!)
  • often cloudy/showers/thunderstorms/sometimes severe
• What does a vertical cross section through a front look like??
