I later flew chemplanes that used a pressurized system due the the altitudes involved

They seem to have discarded the wingtip devices for more aerodynamic pyrotechnic flares. The flares look to be attached to the flap area near the fuelage. The flares apperantly have silver iodine in them, and they are shot into developing storms to reduce the chance of hail.

I have some photos, Ill see if I can get some on here.

We used the wingtip chemtanks for low level seeding (base of a storm), and the ejectable chemflares for the developing tops of a storm.

I did not have the flare racks on the wing, however some chemplanes on different project did. Oklahoma used them for hail suppression, probably to protect the Russian/UN/Chinese/evil Joo troops from hail

I don't keep banning debunkers PHXPilot, but I will ban disruptive trolls. Hard to believe most of you pilots are so young. Quite impressed with your ambition. A word to the wise though, if y'all are really here to try and educate us on aviation, that's cool, but if you girls are here to just be shit disturbers, please note that you won't be around long.

wx-mod flares...yawn...

Im not the one who wrote "S&#% Disturber", because that really isnt my plan. Please forgive the others who said that, they started getting pretty excited

To all other pilots from Airliners .net: Please try not to get banned.

Contrary to what you read on some of these message boards, and what Hitech rants about, Seeding will not cause flooding and does not make a weather system, no more than tuning up your engine puts more gas in your gastank. However it does make the process a little more efficent.

In the photo there, you can see a storm in the growing stages which is when you seed. Timing is extremely important or it will have no effect at all.

If you look at the storm, you can see some areas near the mid level of the storm that are very well defined, and have texture to it. Those areas have liquid (supercooled)water. Those are what are referred to as "feeders"
Fuzzy areas of the storm are ice crystals and seeding would have no effect there.

Top seeding is typically done at altitudes where the outside air temp is -5C to -10C, but where you still have liquid water and updrafts.

The supercooled growing parts of the storm, as long as there are updrafts (so you know the storm is still growing and not dying), are seeding with ejectable flares that give off silver iodide crystals which act as artificial ice crystals. This process starts the icing process, which also released a lot of latent heat when water changes states to ice.

The whole point is to try and get some more water out of the storm. But in the best case, you might get 10% more, and in the worse case you get nothing. Its not something magical or sinister. Not all scientists believe in it either.
