The summer coastal winds of 1982-3 were anomalous in two respects: 1) the effect of cyclonic perturbation was stronger in the south, resulting in weaker seasonally integrated longshore winds and a larger than normal eastward (onshore) component; 2) in the north, the cumulative longshore wind was slightly stronger than normal, with more upwelling, colder water and lower air temperatures at the coast. The cause of this may perhaps be found in steeper cross-coastal pressure gradients with a stronger component of geostrophic wind aloft.-from Authors English

... spond more to Figures 2c and2d, and to Figure 3, though obviously only including summer. Figure 6 shows that there is a tendency for weaker southerly winds at Cape Town during ENSO events; Nelson and Walker [1984] also found that the southeasterly winds were much weaker during 1983 compared with 1981. The increasing wind stress trend reported by Bakun [1990] does not appear, though after an initial decrease in wind stress until 1960, there then appears to be a slow increase. ...
