Meteorological Conditions Associated with Bow Echo Development in Convective Storms

Most observational and numerical modeling investigations into the meteorological factors affecting bow echo development in the United States have concerned long-lived events occurring during the late spring and summer. As a result, the meteorological patterns and parameter values (conceptual models) typically associated with bow echo development are biased toward the larger-scale warm season events. This note discusses the spectrum of meteorological conditions observed with bow echo development and extends the classification of associated meteorological patterns to cool season cases.
