Using fires or heat sources to influence convective circulation or to evaporate fog;
Modifying the solar radiation exchange of the earth or clouds, through the release of gases, dusts, liquids, or aerosols into the atmosphere;
Modifying the characteristics of land or water surfaces by dusting or treating with powders, liquid sprays, dyes, or other materials;
Releasing electrically charged or radioactive particles, or ions, into the atmosphere;
Applying shock waves, sonic energy sources, or other explosive or acoustic sources to the atmosphere;
Using aircraft propeller downwash, jet wash, or other sources of artificial wind generation;
