Relationships between Rainy Days, Mean Daily Intensity and Seasonal Rainfall in Normal, Flood and Drought Years over India
Keywords: Monsoon rainfall,Linear relationship,Logarithmic relationship,Mean daily rainfall intensity,Seasonal rainfall Abstract: There are limitations in using the seasonal rainfall total in studies of Monsoon rainfall climatology. A correlation analysis of the individual station seasonal rainfall with all India seasonal mean rainfall has been made. After taking the significance test (strictly up to 5% level) the stations which are significantly correlated have been considered in this study in normal, flood and drought years respectively. Analysis of seasonal rainfall data of 50 stations spread over a period of 41 years suggests that a linear relationship fits better than the logarithmic relationship when seasonal rain-fall versus number of rainy days is studied. The linear relationship is also found to be better in the case of seasonal rainfall versus mean daily intensity.
