WeatherTec™ relies on natural processes to enhance rainfall using either orographic (above) or convective updrafts

Targeting locations for rain enhancement depends on understanding local atmospheric conditions:

• Sites where orographic and convective clouds form (to provide the basis for the rain cloud)
• Aerosol concentrations and sizes (to provide the charge transport medium)
• Wind updrafts and cloud formation areas (to get the charge into the cloud)
• Wind speed and direction (determines how far clouds travel before rain enhancement starts).
