    1. Chapter 6: mesoscale gravity waves This ppt summarizes the slides in the textbook. The theory is covered in class. Note: this ppt does not include section 6.6 Bores.

    8. Fig. 6.1: isochrones of a mesoscale gravity wave crest during a major East Coast snowstorm. The wave was detected in the pressure trace. The wind barbs indicate the vector surface wind shift upon wave passage. x Greensboro (GSO)

    9. moist adiabat (qw=16°C) dry adiabat (q=46°C) Fig. 6.9: the mesoscale gravity wave event may have been triggered by elevated convection, or gravity wave adjustment. The stable low-level layer may have allowed wave ducting towards the NE. qw values (°C)

    10. Fig. 6.11: synoptic setting of gravity wave activity (p’~ a few mb)

    11. Fig. 6.2: SLP analysis in a Midwest snowstorm. dotted lines: wave crests, dashed lines: troughs

    12. Fig. 6.10: schematic of a linear plane mesoscale gravity wave propagating to the right (Uo=0)

    13. see youtube video

    14. Fig. 6.6: polarization relations between q’, p’, u’, and w’ in a westward tilting internal gravity wave blue = cold, red = warm

    15. Critical level: level where wave energy is absorbed cg c Fig. 6.7 Fig. 6.8

    16. geostrophic adjustment: principle • Rossby radius of deformation: • see COMET module • “the balancing act of geostrophic adjustment” • see YouTube video: • geostrophic adjustment: inertio-gravity waves and the Coriolis force

    17. Will a feature last or dissipate? Estimate its LR
