Abstract: A climatology of meteorological parameters and synoptic patterns associated with severe weather outbreaks occurring in arm where the mid-tropospheric flow has a north of west component is presented. This climatology utilizes ...

Abstract: A climatology of severe weather outbreaks occurring in areas of the contiguous United States where the mid-troposphere flow has a north of west component has been developed for the period 1962?77. During the 16 years, 163 ...

Abstract: 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 ...

Abstract: The derecho, a widespread convectively induced windstorm, is identified and defined in terms of current nomenclature. A comprehensive dataset consisting of 70 derecho cases has been developed from the warm season months ...

Abstract: Extratropical cyclones over the central United States and southern Canada from the years 1982 and 1989 were examined for the presence of two or more (multiple) warm-front-like baroclinic zones, hereafter called MWFL ...

Abstract: A climatology of nonfreezing drizzle is created using surface observations from 584 stations across the United States and Canada over the 15-yr period 1976?90. Drizzle falls 50?200 h a year in most locations in the eastern ...

Abstract: On 5 July 2002, a rapidly propagating bow echo formed over eastern Finland causing severe wind damage in an exceptionally large area. The Ministry of the Interior?s Emergency Response Centers received nearly 400 ...
