Cloud Formations Around Everest

The pyramidal shape of Mount Everest and high winds produce a unique type of cloud known as “Banner Cloud.” The Banner Cloud can be seen on cloudless days on the lee side of the mountain.

This forms strong winds around the mountain and creates a temporary low-pressure cell on the lee side which further creates moisture. Everest is the only mountain that projects into the jet stream. The shape of the cloud on the summit is at a right angle to the peak. When it’s stronger around 50 Mph it tilts down and tilts up when it’s weaker.

Precipitation Pattern Around Mount Everest
