050 Meteorology

EASA code: 050

Meteorology covers the atmosphere and ISA, heat transfer and stability, wind systems, cloud formation, visibility and fog, air masses and fronts, thunderstorms and icing, jet streams and windshear, plus METAR/TAF interpretation.

Chapters

1. Atmosphere & heat — composition, ISA, heating, lapse rates, humidity
2. Pressure & wind — QNH/QFF, geostrophic wind, friction layer
3. Clouds & precipitation — classification, triggers, Bergeron, coalescence
4. Visibility & fog — radiation, advection, frontal fog, RVR
5. Fronts & airmasses — PFD, occlusions, anticyclones, TRS
6. Thunderstorms & icing — CB stages, microbursts, airframe icing
7. Windshear & jetstream — CAT, mountain waves, jet core
8. Key notes — exam quick reference

Exam focus

• ISA values, density altitude, QNH vs QFF vs QFE
• High to low, look out below; 4% per 10°C ISA deviation
• DALR 3°C/1000 ft; SALR 1.8°C/1000 ft; stability rules
• Warm front vs cold front cloud and weather sequences
• Jet stream location, CAT on cold-air side
• METAR/TAF codes, CAVOK, RVR trends
