| Zusammenfassung |
| In this paper, aircraft measurements are presented of liquid phase
(ice-free) wave clouds made at temperatures greater than −5°C
that formed over Scotland, UK. The horizontal variations
of the vertical velocity across wave clouds display a distinct pattern.
The maximum updraughts occur at the upshear flanks of the clouds and
the strong downdraughts at the downshear flanks. The cloud droplet
concentrations were a couple of hundreds per cubic centimetres,
and the drops generally had a mean diameter between 15–45 μm.
A small proportion of the drops were drizzle. The measurements presented
here and in previous recent studies suggest a different interaction
of dynamics and microphysics in wave clouds from the accepted model.
The results in this paper provide a case for future numerical
simulation of wave cloud and the interaction between wave and cloud. |
