Water droplet fogs formed from Pyrotechnically Generated Condensation Nuclei
Keywords:Weather Modification Research, Impacts of Human Activity
A pyrotechnic formulation is described which, upon burning, produces 9 .6 x 10^12 g of sub- and super-micron condensation nuclei (mean diameter ~ 2 um). The largest particles measured were 5 um diameter. The particles are composed of KCI, NaCl and Li2CO3. These particles deliquesce and form water droplet fog in stable, calm environments with relative humidities (RH)>75%. Fogs formed at RH>90% are composed of sub- and super-micron droplets (mean diameter ~ 8 um). The largest droplets measured were 10 um diameter. The droplet populations >5 um resemble those found in coastal fogs.
