Midlatitude Cyclones (Storms)

Midlatitude Cyclones (Storms). Extratropical cyclone or wave cyclone or frontogenesis or storm Low pressure area with counter-clockwise circulation. Atmosphere collects water as water vapor in evaporation from oceans, lakes. It is returned via precipitation, often caused by storms.

Presentation Transcript

  1. Midlatitude Cyclones (Storms) • Extratropical cyclone or wave cyclone or frontogenesis or storm • Low pressure area with counter-clockwise circulation. • Atmosphere collects water as water vapor in evaporation from oceans, lakes. • It is returned via precipitation, often caused by storms.

  2. Storms Center of intense low pressure with cyclonic circulation and resultant precipitation. • Midlatitude Cyclone • Hurricane • Tornadoes • Not thunderstorms, no cyclonic motion.

  3. Cyclogenesis in Action:Mid-latitude (extratropical) cyclones

  4. Air MassesDefinition: volume of air with same temperature and humidity characteristicsSource Regions: where air masses come from.Classification: warm or cold, moist or dry

  5. Air Masses Affecting North America

  6. Frontogenesis

  7. Occluded Front: The Death of a Storm

  8. Occluded Front

  9. Weather Maps

  10. Today’s Weather Map Weather Maps

  11. Storm Tracks: North America Storms (Storm Tracks) generally travel from West to East in North America all year They shift North in summer & South in Winter Actual Storm Tracks (1991) Average Storm Tracks Moving West To East

  12. Midlatitude Cyclone Characteristics Motion:these storms move across the midlatitudes at about 30 m.p.h. from west to east as they rotate once around a low pressure center. Size: roughly 1,000 miles in diameter, the largest of storms Lifespan: 3-6 days to develop, 3-6 to dissipate Pressure: center roughly 990-1000 mb (1-2 % drop)
