orographic clouds
Clouds formed as a result of orography, or terrestrial relief. If a mass of moist air moves against a hill, it will rise and cool. Clouds will form if in this process the condensation level is reached and precipitation can occur. If precipitation does not occur, the cloud base on the leeward sides will be higher than the clouds on the windward side of the hill. As these clouds are linked with the form of the terrestrial relief, they generally move very slowly, if at all. The winds at the same level may be very strong.

The Seeded and Natural Orographic Wintertime Clouds: The Idaho Experiment (SNOWIE) project aims to study the impacts of cloud seeding on winter orographic clouds. The field campaign took place in Idaho between 7 January and 17 March 2017 and employed a comprehensive suite of instrumentation, including ground-based radars and airborne sensors, to collect in situ and remotely sensed data in and around clouds containing super-cooled liquid water before and after seeding with silver iodide aerosol particles.
Orographic clouds often cover Olympus Mons, the planet's largest extinct volcano, making it look like a pale, white pustule in the ochre desert.

What is certain is all of Montana's mountain ranges were capped with orographic clouds and mountain wave activity, and were comprised of shallow but extensive convection due to a layer of instability between the surface and 12,000 feet.

The only probable place where cloud seeding could be successful, Alpert said, is when seeding is performed on orographic clouds, which develop over mountains and have a short lifespan.
