| Abstract: | From a study of rainfall series at several locations, it is shown that approximate but meaningful predictions of drought-prone intervals are possible only for regions where the rainfall series have prominent periodicities (of large amplitudes) in the long periodicity region (about 10 yr or more), provided the patterns do not change abruptly and drastically. Also, rainfall for individual years cannot be predicted accurately. |
