Figure 3-4. Mean 700 mb contours (tens of feet) for December 1974 (Taubensee 1975). Bering Sea shelf and the freezing degree days of the previous winter. Moreover, Niebauer (1980) has found significant correlation between mean annual SST (Fig. 3-1) and mean winter cloud cover and mean winter north-south component of the surface winds but not with summer cloud cover or winds. This is interpreted to mean that the large-scale deviations from mean air and sea temperature in the eastern Bering Sea depend on winter atmospheric advective processes. Insolation is important in the seasonal heating and cooling cycle, but apparently has little effect on interannual deviations from the mean. The strong summer insolation also "caps" the shelf water between the 50 and 100 m isobaths through the formation of a strong thermocline. This, along with the low net flow, insulates the heat content of this water which has been acquired during the winter. This mechanism probably also accounts for the high SST autocorrelation coefficients up to two years later which, in turn, suggest that short-term climatic fluctuations may also persist for at least two years.
