I spent twelve days in Pioneer Valley, northeast of Flagstaff, Arizona photographing the summer thunderstorms associated with the monsoon weather. I shot over 70,000 exposures to assemble a dozen time lapse movies. It was the most spectacular monsoon weather I have seen in many years. Every day brought new phenomena. Each mountain creates its own orographic clouds. Look for cumulonimbus clouds that spread out when they reach the stratosphere. Lenticular clouds hover over the mountains when the speed of the air mass increases.
I spent several days in Pioneer Valley, northeast of Flagstaff, Arizona photographing the summer thunderstorms associated with the monsoon weather. Warm, moist air from the Gulf of Mexico moved into the area on Thursday, July 19.
I spent several days in Pioneer Valley, northeast of Flagstaff, Arizona photographing the summer thunderstorms associated with the monsoon weather. Warm, moist air from the Gulf of Mexico moved into the area on Thursday, July 19. I shot exposures at five second intervals to assemble a time lapse movie. At night the exposures were four seconds long to capture the flashes of lightning.
I reprocessed the lightning sequences from my Monsoon Weather Over Flagstaff video to improve the visibility of the lightning.
A low pressure zone hovering over southern Utah directed unstable air into northern Arizona from the west, opposite the usual monsoon flow. Cumulus clouds form over the San Francisco peaks, building to the stratosphere, becoming cumulonimbus clouds that drop heavy rain, and spout downbursts. as they drift across the landscape. The speed of the action in this time lapse movie has been increased by a factor of 120.
Warm, moist air from the Gulf of Mexico brings turbulent air, cumulus clouds and localized showers to the Flagstaff area. Towering Cumulonimbus clouds rise seven miles to the bottom of the Stratosphere and then spread across the sky. The San Francisco Peaks can be seen to produce their own orographic cloudes. This movie was shot from August 24 to August 27. The speed of the action in this time lapse movie has been increased by a factor of 120.
This movie was shot from August 28 to August 31.
