  • Patent number: 4653690
    Abstract: The disruption of a thermal inversion and formation of cumulus clouds is duced by the ignition of a pyrotechnic composition containing an alkali earth metal. The combined heats of hydration, condensation and combustion of the composition disrupt the thermal layer allowing the passage of warm moist air into a zone of cooler air. The formation of cumulonimbus or cumulus clouds results.
