Presentation Transcript

  1. Some Unpublished TLS Results*: • Evolution ofMH, hmin-shear, hmax-N2 on TLS Profiles • Compare MH, hmin-shear, hmax-N2 on a 2-day scatter plot • Examine NBL “top” using TLS(ε) and Tower (w2 ) • Upside Down Boundary Layer (TLS + Tower Profiles) • Hi-Resolution Entrainment Region Measurements • Residual Layer (can be a pretty dynamic region) • TLS Profile Showing King-Air Generated Turbulence • Lidar, Sodar, TLS Comparison Profiles JAS (accepted) JAM (in final revision) * B. Balsley, R. Frehlich, M. Jensen, Y. Meillier

  2. TLS Analysis Techniques:

  3. SBL* Evolution: (10/20/99, 0707-1216 UT) MH (-o-),hmin-shear (____), hmax-N2(……) *Traditional Boundary Layer (Profile separation ~ 30 min}

  4. Relationship Between MH, hmin-shear, hmax-N2 (Oct 14th & 20th)

  5. 10/20/99 (0719 UT): MH Estimates via TLS(ε) and Tower (w2 ) w(t) at 20m & 55m TLS Tower MH MH

  6. 10/20/99 (0850 UT): MH Estimates via TLS(ε) and Tower (w2 ) TLS Tower w(t) at 20m & 55m ?? MH

  7. CASES (10/14/99) 10.8 UT: High Vertical Resolution (~0.25 m) Energy Dissipation Rate (ε) Profiles in the Entrainment Region at 26 Sec. Intervals Energy Dissipation Rate (ε)

  8. 10/14/99 0200-1300 UT MH, hmin-shear, hmax-N2 Vs Time

  9. 10/14/99 (0849-1203 UT):Examples of ε, w2, <w’3> & <wt’>

  10. The “Residual” Layer: Not a Passive Region;10/21/99 ~0715 UT (4 sensors; 3m separation) 103 102

  11. 10/20/99 Example of a King-Air Exhaust “Trail” Advected Through a TLS Profile 1000 times stronger than ambient turbulence level

  12. Compare Profiles: TLS (black), Sodar (blue), Lidar (green, red) (The Pentagon 21 May 2004)
