Values of (Palmer’s) drought index computed for 23 sub-divisions of India for a period of about 60 years have been examined by power spectrum method. Very few of the peaks are significant as 95 percent level though persistence in the some sub-divisions is indicated. No definite periodicity could be recognized in these series and even the oscillatory character noted in some of them need further critical examination.
