Cloud-seeding is a technique to enhance rainfall by introducing particles - often silver iodide crystals - into cloud systems, to help condense water vapor into raindrops.
Apparently the effects of jet planes punching through clouds are similar to "cloudseeding" operations, where ice crystals are created in the atmosphere to make it rain.
显然，飞机穿过云层与“云种散播效应”类似，在空中形成的冰晶会导致降雨。

Regardless of the Moscow authorities' final decision on snow cloudseeding, Russia remains one of the few nations where weather control is more than using anti-hail cannons and battling droughts.
