摘要 使用来自等压表面的大气数据计算了水平风的发散部分对垂直剪切流和垂直平均流之间的能量转换的贡献：850、700、500、300和200 mb。新的计算补充了先前的计算，给出了基于水平风不发散的假设的能量转换。研究发现，与非发散部分相比，水平风发散部分的贡献通常很小。事实上，前者的能量转换通常与零没有显着不同。 1962-63 年的异常冬季已被单独调查。研究发现，该时期发散风分量的能量转换比任何其他时期都要大得多，并且占总转换的比例更大。
Abstract The contribution from the divergent part of the horizontal wind to the energy conversion between the vertical shear flow and the vertical mean flow has been computed using atmospheric data from the isobaric surfaces: 850, 700, 500, 300, and 200 mb. The new calculations supplement earlier computations giving the energy conversion based on an assumption that the horizontal winds are non-divergent. It is found that the contribution from the divergent part of the horizontal wind normally is very small compared with the contribution from the non-divergent part. The former energy conversion is as a matter of fact generally not significantly different from zero. The abnormal winter 1962–63 has been investigated separately. It is found that energy conversion by the divergent wind component during this period was much larger and constituted a larger fraction of the total conversion than during any other period.
