Abstract : Shear measurements from the MILE current meter observations are statistically analyzed. Much of the shear is inertial, and probability density histograms of short-term records are bimodal. Over three inertial periods, shear distribution approaches Gaussianity. We derive a simple statistical model of shear, which predicts how mean-square shear varies with stratification and vertical separation 5z. We compare these predictions with MILE observations. We also show that 15-minute average samples of N2 and S2 are significantly correlated. Knowing the 15-minute 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)
