| Popis: | Water temperature measurements have been made from a ship steaming continuously around a 10 km square on the north shore of Lake Ontario during a vigorous upwelling and downwelling cycle generated by a fall storm. These measurements reveal the existence of horizontal eddies and meanders within the coastal boundary layer having scales between 1 and 10 km. Active internal waves and a rich vertical microstructure are also observed. The above features are considered to be indicative of horizontal and vertical mixing processes generated by large-scale (10 km) adjustments of the coastal boundary layer. The wealth and diversity of the small-scale features suggest that the usual methods of parameterizing geophysical turbulence in terms of large-scale motion will be of little use in the coastal zone and, consequently, the outlook for deterministic modeling of the coastal flow regimes is not bright. It is concluded that very simple dynamical models of the large-scale motions allow one to divide the shoreli... |
