平衡点

_ FDEPS のセミナー中(その3) しんどい.

昨晩, 今日の為にプレゼン資料作って下さったみたい.

ありがとうございます大先生.

_ non-liner saturation of vertically propagating Rossby waves

今日のネタその 1.

• Giannitsis, C. and R.S. Lindzen (2001) Non-linear saturation of vertically propagating Rossby waves. accepted J. Atmos. Sci.[pdf]

結論

• The growth of vertically propagating planetary scale Rossby waves does give rise to wave 'breaking' as indicated by the wrapping of PV contours
• The saturation of the primary Rosbby wave is not due to wave breaking. Rather, it is associated with wave-mean flow interactions wherein either critical surfaces or reflecting surfaces are created. The development of these features is associated with the development of closed (Eulerian) streamlines.
• Wave-wave interactions are quantitatively important. However, the most important wave-wave interactions involve wavenumbers 1 and 2, and these are not crucial for the 'breaking' signature.

_ Baroclinic adjustment and equilibration

今日のネタその 2.

• Zurita-Gotor, P., Lindzen, R. S., 2006: Theories of baroclinic adjustment and eddy equilibration. In Recent Results in General Circulation Theory. T. Schneider and A. Sobel, Editors. Princeton (in press)

convective adjustment が対流調節だから, baroclinic adjustment は傾圧調節, とでも訳されるのかな.

…かな(要,論文解読).
