Ice drift derived from the Polar Ice Prediction System (PIPS) is used to study the sea ice circulation of the Beaufort and Chukchi seas in the late summer. Model simulations for the years 1983, 1986 and 1987 show that the anticyclonic Beaufort Gyre reverses to cyclonic circulation in the late summer. This result is due to a change in the mean atmospheric surface pressure. Drifting buoys from 1983 confirm this reversal of the Beaufort Gyre. Sea ice models, Ice drift, Beaufort gyre.
