carried slowly by a current of air or water
a drifting ocean liner
behind them rose the broken highlands crowned with drifting clouds
(especially of snow or leaves) blown into heaps by the wind
long stretches of drifting snow
be carried slowly by a current of air or water
the cabin cruiser started to drift downstream
excited voices drifted down the hall
(especially of snow or leaves) be blown into heaps by the wind
fallen leaves were starting to drift in the gutters
