3 Questions
Match the following cloud types with their respective coding in the observation report:
Altocumulus perlucidus or Stratocumulus perlucidus (mackerel sky) = N = 7 or less Blue sky or stars seen through fog without any trace of cloud = N = 0 Persistent condensation trails and cloud masses developed from them = CH or CM code figure Clouds observed through fog or analogous phenomena = Evaluated as if phenomena were non-existent
Match the following cloud characteristics with their reporting instructions:
Altocumulus perlucidus or Stratocumulus perlucidus (mackerel sky) = Report using N = 7 or less Blue sky or stars seen through fog without any trace of cloud = Code N as 0 Clouds observed through fog or analogous phenomena = Evaluate and report as if phenomena were non-existent Persistent condensation trails and cloud masses developed from them = Report as cloud using appropriate CH or CM code figure
Match the following wind reporting guidelines with their descriptions:
ddff notation = Mean direction and speed of wind over preceding 10-minute period Discontinuity in wind characteristics during 10-minute period = Use data obtained after discontinuity for mean values reporting Absence of wind instruments = Estimate wind speed based on Beaufort wind scale Rapidly dissipating condensation trails = Not included in total cloud cover amount
Learn about how to accurately report cloud observations based on the appearance of different cloud formations. Understand how to code observations when specific types of clouds are seen or when no clouds are present in the sky.
