| 摘 要： | 本文用1979年夏季风试验时期(MONEX)得到的专门观测资料计算了孟加拉湾地区一个季风低压的能量收支,得到(1)无辐散风动能制造项是低压的主要动能制造项。在整个低压生命期,平均无辐散风动能制造为7.40瓦/米~2,辐散风动能制造为0.67瓦/米~2。这表明正压能量制造过程的重要性;(2)对于扰动动能收支,斜压能量转换和正压能量转换都有重要作用。另外通过边界通量,低压总是从环境得到扰动动能的。

| Abstract: | The budget of kinetic energy of a monsoon depression over the Bay of Ben-gal has been estimated utilizing the special Observation data set obtained during 1979 Summer MONEX. It has been found that: (1)The generation term of kinetic energy by non-divergent wind is the main source term of kinetic energy.The ave rage generation rate of kinetic energy by non-divergent wind for the entire life span of the depression is 7.40w/m2, while the average generation rate of kinetic energy by divergent wind is 0.67w/m2.This fact indicates the significant importance of the barotropic energy transformation process. (2) For the budget of eddy kinetic energy, both baroclinic and barotropic energy transformation processes are important. In addition, the depression also acquired eddy kinetic energy from the surroundings through the boundary flux term. |
