我们提出了一种大气环流模型研究，研究瞬态、垂直受限强迫后扰动的时间增长和垂直传播。进行了五组扰动实验，每个实验都有八种不同的初始条件，并在从对流层下部到平流层上部的十个不同垂直水平上实施扰动。 The motivation for the study is the recent recognition of downward propagation of anomalies from the stratosphere to the troposphere and its implications both for medium‐range forecasts and for a possible physical mechanism for stratospheric impacts on weather and climate.
We present a general‐circulation model study of the temporal growth and vertical propagation of perturbations following transient, vertically confined forcings. Five ensembles of perturbation experiments are performed, each with eight different initial conditions and with the perturbations enforced at ten different vertical levels from the lower troposphere to the upper stratosphere. The motivation for the study is the recent recognition of downward propagation of anomalies from the stratosphere to the troposphere and its implications both for medium‐range forecasts and for a possible physical mechanism for stratospheric impacts on weather and climate.
