Abstract

The Great Plains low-level jet (GPLLJ) contributes to Great Plains (GP) warm season water resources (precipitation), wind resources, and severe weather outbreaks. Past research has shown that synoptic and local mesoscale physical mechanisms (Holton and Blackadar mechanisms) are jointly required to explain GPLLJ variability. Although local mechanistic theories hinge upon soil moisture-planetary boundary layer (PBL) interactions, the effect of regional soil moisture anomalies on GPLLJ speed, northward penetration, and propensity for severe weather is not well known.
