The isotopic content of precipitation falling at a point provides information of potential importance concerning atmospheric circulation and climate change1–6. The isotopic content of precipitation, however, is controlled by the particular meteorological processes acting at a given time and place and is subject to considerable variation. We have measured the deuterium-to-hydrogen ratios (D/H) of precipitation at Mohonk Lake, New York, from individual storms over a 2-yr period, July 1977–June 1979. These ratios varied systematically with the locus of the paths followed by the storms: the more seawards (and southerly) the paths and the colder the temperatures at Mohonk, the lower were the D/H ratios.
