The Development of High- & Low-Pressure Systems

Online 8.2: Jetstreaks, flow curvature, and low-pressure systems

300 mb Heights & Wind
- The series of 300 mb maps show the evolution of the jetstream during the development and evolution of a surface low-pressure system. The surface low-pressure system created blizzard conditions in Iowa, Nebraska, and northern Illinois. Identify the regions of maximum divergence associated with curvature and the jet streaks. Examine the sea level pressure animation to verify your understanding.
