Cloud seeding was originally implemented in drought-stricken agricultural areas. Current seeding procedures use turboprop and jet aircraft that chill the air in mid-level clouds, causing bands of snow and rain to develop and fall. Holes left behind in the clouds are called hole-punch or canal clouds causing inadvertent cloud seeding. Recent discoveries have found that aircraft propellers and jet wings produces as much chilled precipitation as cloud seeding. Years ago, researchers from Hebrew University attempted to eliminate the fury of hurricanes by injecting smoke particles into the lower sections of a hurricane causing water vapor to condense; stunting the raindrops. Ten cargo planes with smoke particles would be needed to attack a storm.
