英文摘要: This paper introduces a new analysis method that can isolate the responses to specific forcings within meteorological data. By using the zonal mean primitive equations on the sphere, it is possible to break down the meridional circulation, the acceleration of zonal wind, temperature change, and surface pressure change into their individual contributions, which are directly associated with various forcings. This analysis technique can be applied to a wide range of problems relating to climate and its variability. To demonstrate the application of the technique, the formation and maintenance of the subtropical jet during the Northern Hemisphere winter are examined. It is found that atmospheric waves play a crucial role in both the climatological maintenance and the day-To-day (and month-To-month) variabilities of the jet. While stationary waves are the dominant catalyst for maintaining the jet in its climatological state, synoptic waves play an important role in generating the month-To-month variability of the jet. © 2016.
