Figure 22: (a) Time variation of winter wind stress over tbe central Labrador Sea,
smootbed and unsmootbed, from data of Drinkwater; see Rhines, 1994. (b) Tbe annual
vector-averaged NW wind-stresses for tbe Labrador Sea (average of 6 sites). Negative
stresses indicate winds from NW. From Drinkwater, 1994. (c) Mean wind stress curl
at 55N, 50W and 55N, 45W, based on surface daily NMC pressure fields. From Giles
