Mount Rainier creates several almost every day. Sometimes it will wear
a cap for many days. It's an air compression humidity thing. They are
formed by strong updrafts acting upon moist air at lower altitudes,
causing the air to cool to its dew point as it reaches the mountaintop
where it wraps around it . The cooled air then falls into the warmer
air and the condensed moisture dissipates (disappears).
I think...
In Yorkshire they're caused by smug clouds of self-satisfaction mingling
with the hot steam rising from the chips on their shoulders.
Which is why those particular clouds smell of beef dripping.

these are fairly common in the Colorado front range, especially in
Boulder where i lived for some time; i understand they form as a result
of a standing wave in the atmosphere; the examples on the BBC page are
very fine and more multi-layered than we are used to seeing
