formulated by Palmer (1965) and compares the actual amount of precipitation
received in an area during a specified period with the normal or average amount
expected during that same period.

The PDSI is based on a procedure of hydrologic or water balance accounting by
which excesses or deficiences in moisture are determined in relation to average
climatic values."""@en ;
