I don’t understand why I don’t see (cloud) billows as often around here as I have seen them elsewhere. These billows are formed in a thin atmospheric layer where the temperature and wind change markedly with height. The airflow is almost as it looks: a series of rollers. Billows can form on a wave cloud, which is the case here.
This morning’s billows on a wave cloud were seen for only about fifteen minutes and then they vanished.
beautiful!
