尾流对海洋反馈机制的响应:马德拉岛个例研究

Wake response to an ocean-feedback mechanism: Madeira Island case study

R. M. A. Caldeira, R. Tomé

摘要:

讨论的重点是尾流事件的数值研究。天气研究和预报模型是以缩小尺度的方式使用的。目前的文献主要讨论大气尾迹的绝热动力学。山的高度变化,从而对它与大气逆温层的关系应该解释的转变后,制度:从“强尾流”到“弱尾流”的情况。然而,SST变率的变化也可以引起类似的制度转变。蒸发的增加有助于增加对流,从而使分层大气层上升到临界高度以上,随后出现重力内波活动。

英文摘要:

This discussion focused on the numerical study of a wake episode. The Weather Research and Forecasting model was used in a downscale mode. The current literature focuses the discussion on the adiabatic dynamics of atmospheric wakes. Changes in mountain height and consequently on its relation to the atmospheric inversion layer should explain the shift in wake regimes: from a 'strong-wake' to a 'weak-wake' scenario. Nevertheless, changes in SST variability can also induce similar regime shifts. Increase in evaporation, contributes to increase convection and thus to an uplift of the stratified atmospheric layer, above the critical height, with subsequent internal gravity wave activity.
