中文摘要:
      本文对大型天气转变过程中北半球500毫巴上波谱进行了分析。结果表明,波数为5的波在这次转变过程中起主要作用。在纬向式环流崩溃过程中,中纬度角动量的输送是向北的[6],这个向北的输送主要是由波数为5的波动完成的。在纬向式环流生成过程中,中纬度角动量的输送是向南的,它也主要是由波数为5的波动完成的。
英文摘要:
      The spectra of kinetic energy, transfer of angular momentum and energy transformation between eddy and tonal kinetic energy are analysed for a period of large-scale,synoptic variation. It is, shown that the wave of wave number five plays an important role in the change of circulation. During the breakdown of tonal circulation the angular-momentum transfer is northward[6], and this northward transfer is accomplished‘ mostly by the wave of wave number 5. During the formation of tonal circulation the transfer of angular momentum is southward[6] and this is also mostly accomplished by the wave of. wave number 5.
