Yes, the govt has done seeding experiments like Project Stormfury to try to weaken storms. Heck, the first one seeded was in 1947, which initially may have actually successfully weakened it as it did weaken while moving NE on a seemingly safe heading OTS. But afterward it made a sharp 135 degree left turn and hit Savannah as a restrengthening H. That initial weakening may have lowered the mean steering level enough to inadvertently allow a high to the N to steer it westward. We’ll never know. They certainly weren’t trying to get the storm to turn. They seeded only because it was seemingly moving safely OTS.
But regardless, bringing up these past experiments is a red herring to change the subject from what MTG and others are now doing for pure political purposes.
