论大气运动的多时态特征——适应、发展和准定常演变

On the Characteristic of Multi-time Stage of Atmospheric Motion

对中国气象学家在地转适应和运动多时态特征方面的研究作了概要性总结。其中主要介绍在风、压场的地转适应以及适应过程完成后，尚可区别出以Ｒｏｓｂｙ波频散为特征的发展过程，和以平流过程为特征的准定常演变过程。文中指出，运动的多时态特征是由于动力系统中存在多种物理过程造成，因此在小尺度、中尺度以及热带大心度运动中都存在适应、发展和准定常演变过程。文中进而指出，这种态特征也存在于海气耦合的气候系统中，以及更复杂的气候系统中，也即带有一事实上的普遍性。

A brief review on the characteristic of multi-time stage of atmospheric motion is given. These ideas are developed mainly by Chinese meteorologists. The development of the atmospheric large-scale, meso-scale and small-scale motion and tropical motion consists essentially the three stages, namely the adjustment stage (called geostropic adjustment for large-scale motion), the developing stage and the quasi-steady stage. It is pointed out that the multi-time scale of motion corresponds with the different physical processes in the different dynamical systems including in the air-sea interaction system and in the more complex climate system.
