Week 3 - Conditional Symmetric Instability and High-amplitude internal gravity waves

These phenomena/conditions result in even smaller-scale wintertime weather features

CSI often allows in conjunction with frontogenetical forcing the formation of narrow bands of heavier snow/rain which may be accompanied by thunder

• COMET Module (Use and Misuse of CSI)
• Dr. David Schultz CSI page
• Conceptual model of trowal set up with band locations
• Conceptual model of EPV/frontogenesis and band locations
• Evidence of such bands in 1996 Iowa blizzard (UW-CIMSS)
• Radar image from DVN during big IA blizzard - showing bands

  Occasionally in strong winter storms, wild pressure perturbations potentially accompanied by strong winds and enhanced snow/rain rates occur due to ducted high-amplitude internal gravity waves
