Abstract

The relationship between all-India monsoon (June-September) rainfall (R) and the wind index Vm) is negative (correlation coefficient = -0.72) and is significant at the 0.1 level and the regression equation based on this data, for the period 1964-1988, is R=86.98-2.44 Vm. The stability and consistency of the relationship between rainfall and the wind index have been examined over sliding widths of 15 and 21 years, and the relationship is found to be significant at the 1 level for all windows of 21-yr widths. The meridional wind index shows a good potential in the long-range prediction scheme of the Indian monsoon rainfall, along with other parameters.
