Eye of the Denver Cyclone

Abstract

Observation of an overcast of low cloudiness on a Denver Cyclone day revealed a circular area of clearing or "eye' at the approximate center of the mesoscale circulation. The eye passed close to an automated observing station, providing a time series of data that shows the relationship of the circulation to the cloud-free area. Conditions present in the lower troposphere are examined and compared to conclusions from recent modeling results that suggest the causes of the Denver Cyclone. -Author
