    23. Derive TKE Equation Similarly for v’ and w’

    24. Class Slide MT 454

    25. Class Slide • = Frictional dissipation (molecular diffusion) • > 0 TR = Redistribution by transport & pressure forces (no new TKE created) MT 454

    27. Class Slide MT 454

    28. Analogue in large-scale flow: Class Slide How does this circulation lower center of mass? MT 454

    29. If PBL heated from below, then (z): BPL - TKE increase for unstable PBL BPL > 0 Primary energy source for unstable PBL (In stable PBL, BPL term gives energy loss) w’ < 0 ’ < 0 w’ > 0 ’ > 0 z 

    30. More precise (z) when well-mixed PBL is fully developed. Homogeneous, well-mixed layer Unstable layer maintained near surface by surface heating BPL - Side Note z 
