On the relationship between 5-day mean 700-mb Contour Insolation Anomalies and 5-daymean surface Temperature Anomahes over the Indian region

Abstract

In this note, a study has been made of the geographical distribution of the correlation coefficients between 5-day mean 700-mb contour anomalies and 5-day mean surface temperature anomalies over the sub- continent of India during the winter season. It is seen that the two elements are positively correlated all over Research the above area. The correlation coefficients steadily increase northwestwards, the region with maximum value being located in west Rajasthan, north Gujarat and the neighbourhood. Regression curves have been drawn for the stations Ahmedabad and Jodhpur lying in the above areas and an objective method of forecasting 5-day mean surface temperatures from 5-daymean 700-mb charts has been suggested for these two stations.
