With these coefficients we derive a linear prediction formula for 700-mb contours at 12 radiosonde stations in India. We assume that the predicted 700-mb contour height is a linear function of the contours in the past pentad. The coefficients in Our prediction formula are evaluated by the method of least squares using past data.</p> <p>&nbsp;</p> <p>The usefulness of the method was tested with data of 2 years (1965-66) and we find good success in forecasting broad features on 5-day mean charts.</p>}, number={4}, journal={MAUSAM}, author={SHUKLA , J and SURYANARAYANA, R}, year={1968}, month={Oct.}, pages={407–412} }
