A collection of weather-related, time-lapse videos for the virtual meteorology classroom.
In these two videos, Jim LaDue documents asperatus clouds, the "newest" cloud classification. The first is an example of altostratus asperatus, which occurred on 20 April 2011 in Oklahoma. The second is an example of altocumulus apseratus, which occurred on 15 November 2010. Make sure you "up" the resolution to HD.
