What impact does cloud seeding have on hail?
Though very little research on hail suppression has been done in Texas, we do know from sound research conducted in other parts of the U. S. that seeding for enhancing rainfall very likely lessens the amount, and size, of hailstones. This is because the additional ice crystals injected into a growing thundercloud compete with the hail seeds (or “embryos”) for the available cloud moisture, thereby reducing the chance that many hailstones would grow large. With the ice crystals using more of the available cloud droplets to grow large raindrops, there would be less cloud moisture available to grow the embryos into damaging hailstones. Seeding clouds to suppress hail, on the other hand, appears to increase the efficiency with which the clouds convert the cloud droplets into rain. Thus far, available evidence suggests that seeding for hail suppression, if anything, decreases, rather than increases, rainfall from seeded storms. No evidence has been proffered to suggest that seeding clouds to
