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.
CASE 3: SILVER IODIDE SEEDING OF WINTERTIME OROGRAPHIC CLOUDS
sometimes form over windblown Martian mountains, like orographic clouds
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.
most likely biological INPs) are lost early in the precipitation history of orographic clouds
(Stopelli et al.
Slowly their orographic clouds
began to appear: these are discussed in Part II.
over the Tharsis volcanos, maybe creating the W-Cloud formation?
For example, anthropogenic aerosols that are incorporated from the surface and boundary layer in orographic clouds
can efficiently slow down cloud-drop coalescence and riming on ice precipitation (Rosenfeld et al.
Meteorology has been recorded by many observers, including the usual orographic clouds
over the Tharsis Montes and Olympus Mons.
In 1971 NASA's Mariner 9 spacecraft revealed that these features are waterice-crystal orographic clouds
formed by winds passing over the high peaks.
In addition, the capability of high-resolution models to simulate the physical processes involved in winter orographic clouds
has now been demonstrated (e.
Other fascinating features to watch for include bright orographic clouds
that form over the giant Tharsis volcanoes, such as Olympus Mons, in the Martian mornings and evenings.
