  1. Remember Your location to the Storm center1. Winds – North = Cold, South = Warm 2. Clouds- High – Mid – Low 3. Temperatures – Air Mass, Cold or Warm

  2. Convergence and Divergence Intensifying Surface Cyclone: For example, if a region of diverging winds at upper levels is stronger than the converging winds of a surface low pressure center below it, the low will deepen (intensify). Weakening Surface Cyclone: Storms fills itself

  3. Weather Patterns & Fronts The five types of fronts are(1) warm front, which occurs when the surface (ground) position of a front moves so that warm air occupies territory formerly covered by cooler air, (2) cold front, where cold continental polar air actively advances into a region occupied by warm air,(3) stationary front, which occurs when the air flow on both sides of a front is neither toward the cold air mass nor toward the warm air mass,(4) occluded front, which develops when an active cold front overtakes a warm front and wedges the warm front upward, (5) a dryline, a boundary between dry, dense air and less dense humid air often associated with severe thunderstorms during the spring and summer. The two types of occluded fronts are the cold-type occluded front, where the air behind the cold front is colder than the cool air it is overtaking, and the warm-type occluded front, where the air behind the advancing cold front is warmer than the cold air it overtakes.

  5. Warm Fronts Winds & Temps Warm SectorSouth/Southwest

  6. Type of Clouds • Ci- Cirrus – High thin crystal like. First signs of warm air moving in • As- Alto Stratus- Mid level Blanket • More clouds, higher humidity

  7. Type of Clouds • Nimbo/Nimbus -- Rain cloud, Dark gray. Steady all day rain/snow. • Clouds of Vertical Development - Cumulus and Cumulonimbus. They develop into towers or domes • Cumulonimbus – Thunderstorms, heavy rain

  8. Cold Fronts *Fast Rising Air, Condensation, Clouds *Pressure falls, wind shift

  9. Will it Snow or Rain? • Temperature Profile

  10. Precipitation – Rain, Snow, Sleet, Freezing Rain • Temperature Profile of the Atmosphere.- Is it warm or Cold. Above 32 or below • Rain – All Layers above 32 • Snow – All Layers below 32 • Sleet – Cold, Warm, Cold Layers • Freezing Rain – Warm, Shallow Cold Air

  11. Examples What type of Weather Remember Your location to the Storm center1. Winds – North = Cold, South = Warm 2. Clouds- High – Mid – Low 3. Temperatures – Air Mass, Cold or Warm

  12. Precipitation – SNOW Snow – All Layers below 32 Degrees

  13. Precipitation – Sleet Sleet – Cold, Warm Cold layers

  14. Precipitation – (Glaze) Freezing Rain Freezing Rain – Warm, Cold Surface
