Abstract

Based on 40 year (1963-2002) rainfall data of CR Farm, CAZRI, Jodhpur, the daily normal, monthly, seasonal and annual rainfall have been analyzed. Diurnal variation of rainfall during monsoon showed maximum rainfall intensity in the afternoon and evening. Rainfall received during February has got significant positive correlation with rainfall of July and monsoon season during the same year. By applying Weibulls' formula the return period of 24 hour peak rainfall for Jodhpur is found to be 50 years. M-K rank statistics value and Spearman rank statistics indicated no significant change in seasonal and annual rainfall. Quasi biennial oscillation and half/fractional sun spot cycles are found in some seasonal and monthly rainfall
