Neat Sierra Nevada range standing wave cloud pix.

I took these just tonight (17 May). The cloud parallels the Sierra Nevada mountains on the skyline for about 6o miles from southeast to northwest. Looking northwest.

Picture No. 1 was taken about 7:15 PM.

Picture No. 2 was taken about 7:45 PM.

The clouds form when there are strong winds aloft from the west. This creates a standing wave in the atmosphere and when the wind goes up over the crest of a wave the moisture condenses out. This forms a cloud that stands still even though the wind might be blowing through it at 60-80 mph.

For some reason, clicking on No. 2 knocks me off line. Try this.

Yep, love those Sierras…I’ll be there in 2 weeks.

Yeah, this pretty much sums up my existance. :rolleyes:
