Abstract : Shear measurements from the MILE current meter observations are statistically analyzed. Much of the shear is inertial, and probability density histograms of shortterm records are bimodal. Over three inertial periods, shear distribution approaches Gaussianity. We derive a simple statistical model of shear, which predicts how meansquare shear varies with stratification and vertical separation 5z. We compare these predictions with MILE observations. We also show that 15minute average samples of N2 and S2 are significantly correlated. Knowing the 15minute average value of N2 allows one to predict S2 within a factor of two at least 46% of the time, and within a factor of four at least 75% of the time. (Author)
