Climatic Atlas of Icing Potential Over North America.
Abstract
A climatic atlas of charts that show percent frequency of occurrence of potential icing conditions over North America. Since icing reports are sparse, an accurate icing climatology is difficult to obtain. A climatology of elements for potential icing conditions, however (such as liquid water content and temperature), can be derived. The Smith-Feddes Liquid Water Content (LWC) computer model uses combined data from the Air Force Global Weather Central Three-Dimensional Nephanalysis Data Base (3DNEPH) and the upper air Analysis Data Set for input. Output consists of percent frequency of occurrence of a liquid water content threshold concentration in a defined layer and temperature range. Output was generated for three concentrations, three layers and for temperatures at or below freezing. This data was then manually converted into 117 monthly and annual maps showing percent frequency of occurrence for potential icing conditions.
