3 Regional Gliding School Transition zone between different air masses.Transition zone between different air masses. COLDAIR WARMAIR mixing zone

4 COLDAIR The leading edge of an advancing cold air mass.

5 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

6 Regional Gliding School 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

7 Confirmation Stage NOTE: You must use the buttons in the Confirmation Stage

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

9 I’m afraid that answer is incorrect Let's try again... Flying Scholarship Program

11 I’m afraid that answer is incorrect Let's try again... Flying Scholarship Program

12 That answer is correct. Let's move on...

13 Regional Gliding School A B C D Showers Steady Let's try a few review questions on Meteorology: Question #2 - What precipitation can you expect at a cold front? Mist Continuous MeteorologyFronts

18 Regional Gliding School The trailing edge of a retreating cold air mass Warm air is forced aloft by “overrunning” WARMAIR COLDAIR

19 Regional Gliding School Shallow slope (1 in 200) Wide weather band that may extend up to 500 miles Extensive stratiform cloud FRONTAL SURFACE MILES 1 MILE

20 Regional Gliding School 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

21 Regional Gliding School Sequence of clouds indicating the approach of warm front are: Ccirrus Ccirrostratus Aaltostratus Nnimbostratus Sstratus

22 Regional Gliding School TROWAL 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. A TRough Of Warm air ALoft

23 Regional Gliding School Confirmation Stage NOTE: You must use the buttons in the Confirmation Stage

24 Regional Gliding School A B C D Transition point between fronts Trough of warm air aloft Let's try a few review questions on Meteorology: Question #3 - What does the abbreviation TROWAL stand for? Shallow slope Occluded Fronts MeteorologyFronts

27 I’m afraid that answer is incorrect Let's try again... Flying Scholarship Program

28 That answer is correct. Let's move on...

29 Regional Gliding School A B C D Alto cumulus Alto stratus Let's try a few review questions on Meteorology: Question #4 - What does the “A” in CCANS abbreviation indicate? Altocumulus Castellanus Cumulus MeteorologyFronts

34 Regional Gliding School 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! Meteorology Air Masses
