Presentation Transcript

  1. 4 0 3 . 0 8 Fronts

  2. Transition zone between different air masses. COLD AIR mixing zone WARM AIR

  3. Cold Front The leading edge of an advancing cold air mass. COLD AIR

  4. SLOPE OF A COLD FRONT 1 MILE 50 MILES The slope of the front is very steep (1 in 50) Narrow weather band Can be very severe

  5. Cold Front • Clouds and weather • clouds of vertical development • showers • winds veer • temperature decreases behind front Fast moving cold fronts may produce severe thunderstorms and/or squall lines

  6. Confirmation Stage NOTE: You must use the buttons in the Confirmation Stage

  7. Meteorology Fronts Let's try a few review questions on Meteorology: Question #1 - The slope of a cold front is . A Shallow B Steep C Gradual Vertical D

  17. The trailing edge of a retreating cold air massWarm air is forced aloft by “overrunning” WARM AIR COLD AIR

  18. 1 MILE FRONTAL SURFACE 150 - 200 MILES SLOPE OF WARM FRONT Shallow slope (1 in 200) Wide weather band that may extend up to 500 miles Extensive stratiform cloud

  19. Warm Front • Clouds and weather • stratus clouds • steady precipitation • winds veer • temperature rises behind front • thunderstorms may be embedded in the stratus clouds • in winter, ice pellets and freezing rain may develop

  20. Sequence of clouds indicating the approach of warm front are: • C cirrus • C cirrostratus • A altostratus • N nimbostratus • S stratus

  21. TROWAL A TRough Of Warm air ALoft • A cold front overtakes a warm front and lifts the warm air off the ground. • Clouds and weather • combination of both warm front and cold front weather.

  33. Meteorology Air Masses Congratulations!! You have now completed the Front lesson of the Meteorology Module. Of course, this lesson is always available to you for future reference if required. You are now ready to move along to the next Meteorology lesson you have not completed or to any other module you wish. You can advance to the Self Test Module if you feel ready to challenge the final exam. Good Luck!
