Cloud height prediction
 

Hi all

Any sites out there that offer cloud height prediction? There are some that
offer cloud cover prediction, but no height information. If the cloud is at,
say, 10 000 feet but 8 octas, it is a LOT different from say, 1 000 feet 5-7
octas.

Thanks in advance

Follow this link:-
http://www.westwind.ch/?page=gfs3

then scroll down to the 'Low Clouds', 'Mid Clouds', 'High Clouds'
sections. These will give you a *rough* idea of the model cloud output
banding: low roughly below 7000ft, high roughly above 20000ft, mid in
between (don't get too hung up by the height bands - these are *model*
output remember, but will help you to decide whether the cloud is
significant.

An alternative (where available) is to use the Meteogram output (from
the same GFS model) at:-

http://www.wetterzentrale.de/topkarten/fsavnmgeur.html

follow the links from "Diagramme", then "Europa", and set the second
drop-down box to "Freie Atmosphare" ... then press 'Zeigen': this will
give you output for a single location (set in the left hand box), with
cloud apportioned again to low, medium or high levels. The beauty of
this output is that you can judge for yourself the (rather gross)
thickness of the model cloud (white shading = cloud), and cross-refer to
the relative humidity structure (below - shaded green).
