Abstract

The slow moving waves observed on 5-day mean 700-mb charts were identified by as and Clapp (1944) as long waves in the westerlies. In an earlier study (Pant 1964) it was found some of these troughs affect weather over north India during ~inter and that they have an influence behaviour of the short wave systems observed on daily synoptic charts. Some of the characteristics of these slow moving troughs observed on 5-day mean 700-mb charts like their speed of movement, frequency of occurrence etc, are studied on the basis of mean charts for the period 1957 -62. The troughs Classified into three broad types and their characteristics studied. The results of this study would useful background information to a medium range forecaster.
