Abstract

An ERS 1 SAR image of the Greenland Sea showing sea surface manifestations of atmospheric boundary layer rolls is used to determine the orientation and spacing of the rolls as well as the variation of the sea surface wind speed associated with the secondary flow. Furthermore, the sea surface wind field associated with these rolls is simulated by using a 3-dimensional atmospheric model. It is shown that the model reproduces well the roll spacing and the sea surface wind speed derived from the ERS 1 SAR image intensity
