3 Regional Gliding School CLOUDS Cumulus form in rising air currents and indicate unstable air Stratus form in horizontal layers and indicate stable air

4 Regional Gliding School Families: n LOW (STRATO)surface - 6,500ft n MIDDLE (ALTO)6,500ft - 23,000ft n HIGH (CIRRO)16,500ft - 45,000ft n VERTICAL1,500ft - above DEVELOPMENT Height of Bases:

5 Regional Gliding School

6 CIRRUS (CI) n Thin delicate wisps

7 Regional Gliding School CIRRO-CUMULUS (CC) n Thin cottonball like

8 Regional Gliding School CIRRO-STRATUS (CS) n Thin high sheet n Produces “Halo” effect n Often indicates the approach of a warm front

9 Regional Gliding School

10 ALTOCUMULUS (AC)  Layers of rounded masses of cloud

11 Regional Gliding School ALTOSTRATUS (AS)  Thick grey clouds that often cover the entire sky  May give some light rain or snow

12 Regional Gliding School ALTOCUMULUS CASTELLANUS (ACC)  Altocumulus with turrets

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

14 Regional Gliding School A B C D 1,500-6500 feet 6,500-23,000 feet 16,500-45,000 feet 23,000-45,000 feet Let's try a few review questions on Meteorology: Question #1 - What is the height of middle clouds? MeteorologyClouds

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

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

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

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

19 Regional Gliding School A B C D Altostratus Altocumulus Castellanus Cirrostratus Cirrocumulus Let's try a few review questions on Meteorology: Question #2 - What type of cloud produces a halo effect? MeteorologyClouds

24 Regional Gliding School

25 STRATUS (ST)  A uniform layer, like fog, but not resting on the ground  Drizzle often falls from stratus

26 Regional Gliding School STRATUS FRACTUS (SF)  Pieces of Stratus

27 Regional Gliding School STRATOCUMULUS (SC)  A thin layer of rounded masses of cloud

28 Regional Gliding School NIMBOSTRATUS (NS)  A low layer of uniform, dark grey cloud

29 Regional Gliding School

30 CUMULUS (CU) n Thick n Rounded and lumpy n Resemble cotton balls

31 Regional Gliding School Cumulus Fractus (CF)  Broken Cumulus

32 Regional Gliding School TOWERING CUMULUS (TCU) n Cumulus that builds up into high towering masses n Rough air underneath n Heavy icing in cloud

33 Regional Gliding School CUMULONIMBUS (CB)  Heavy masses of cumulus  Anvil top  Violent vertical currents  CB clouds should be avoided by all aircraft

34 Regional Gliding School Clouds of Vertical Development n n bases as low as 1,500 feet n n composed of: – –water droplets – –supercooled water droplets – –ice crystals.

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

36 Regional Gliding School A B C D Water droplets Ice crystals Supercooled water droplets All the above Let's try a few review questions on Meteorology: Question #3 - What are clouds of vertical development composed of? MeteorologyClouds

46 Regional Gliding School Congratulations!! You have now completed the Clouds 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! MeteorologyClouds
