We have undertaken a computation of water storage fluctuations and their contribution to polar motion excitation for the period 1900–1982. The calculation is based mainly upon monthly mean observations of precipitation at individual stations around the globe. Seasonal average variations are computed for over 500 individual drainage basins, permitting a comparison with observed annual polar motion.
