摘    要:本文考虑到西风宽度有限并存在急流,波动的南北宽度有限并其相对于急流轴的位置可有不同,以及槽脊热力结构的特征等因子,研究了槽与脊的移动速度,讨论了槽脊的发展问题。所得的结果经过试验与实际情况很一致,认为对槽与脊的移动发展的预报甚有实际应用意义。

Abstract:By taking into considerations of the factors such as the intensity of the westerly jet, the latitudinal width of the westerly current, the wave length, the width and latitudinal position of the wave, the distance the jet axis and the latitude with largest wave amplitude, and the thermal structure of the wave the movement and development of the tronghs and wedges in the westerlies are theoretically studied. Formulas for estimating the movement and development are respectively obtained. Application to 24 hours forecasting is tested and illustrated by synoptic examples. It shows that the tested results are good. And it is suggested that the theoretical results can also be applied to fiveday mean maps in the extended forecasting.
