| 摘 要： | 平流层重要变化之一是冬季出现爆发性增暖,这种现象几乎每年都有发生,只是强度不同。本文用“寒潮中期预报理论和方法研究”课题组对波域能量方程的计算方法和结果,用纬向平均地转风、温度、波数域能量方程的一些项,分析了这些物理量对1981年2月中旬一次弱平流层爆发性增暖形成、维持所起的作用,发现2波动能的猛增对增暖有启动作用,1波的动能有维持增暖的作用;对1波和2波动能贡献最大的是BWZ项,次为L1项。

| Abstract: | The energetics of the atmosphere during the December 1980 to February 1981 when a weak stratospheric warming occured was investigated by energetic epuation in the domain of wave number.A rapid and large increase of kinetic energy for wave number 2 had a start contribution. The maintenance of warming was contributed by the kinetic energy of wave number 1.For the increase of kinetic energy of wave numbers 1 and 2, the greatest contribution term was BWZ(n), the next was L1(n),the term-M1(n) had a large contribution in a short time. |
