drizzle drop

drizzle drop

[′driz·əl ‚dräp]
(meteorology)
A drop of water of diameter 0.2 to 0.5 millimeter falling through the atmosphere; however, all water drops of diameter greater than 0.2 millimeter are frequently termed raindrops, as opposed to cloud drops.

"You have to have a kind of drizzle drop, which happens in very intense showers where there is lots of mist.
Drizzle drops, those less than 0.5 millimeter across, are essentially spherical.
The finding should improve understanding of clouds and precipitation formation, as clouds with more vigorous turbulence could have a much stronger clustering signal, which in turn may influence the rate of the droplets' collision in forming drizzle drops. The study could also enhance global climate research, because clustering decreases the lifespan of clouds and subsequently affects the radiation budget and climate.
Drizzle drops are typically 200 to 500 microns in diameter with freezing rain consisting of drops 1,000 to 3,000 microns in diameter or about one to three millimeters.
Observational constraints on these bulk rates can be derived from in situ observations of the drop size distribution, but constraints from Doppler radar in conjunction with passive shortwave and microwave measurements can help constrain the rates of conversion of cloud droplets to drizzle drops and determine the sensitivity of bulk microphysical parameterizations to cloud droplet and aerosol concentration.
