摘要利用1972年安大略湖国际野外年的数据，对大型湖泊的三维水动力模型的性能进行了测试。这些模型在计算细节方面各不相同，但它们的共同目的是根据规定的大气条件预测五大湖的水位、水流和温度。本文所处理的观测期间包括1972年6月下旬热带风暴艾格尼丝通过的时间。利用安大略湖气象浮标网资料，结合安大略湖周围一级天气观测站的常规观测资料，得到了安大略湖风应力和气压场的逐时值。初始温度分布作为深度和水平坐标的函数得到准天气船舶巡航。模型结果的验证是基于湖周站每小时的水位数据和浮标网测量的水流和温度。
Abstract Data from the 1972 International Field Year on Lake Ontario have been used to test the performance of three-dimensional hydrodynamical models of large lakes. The models vary with regard to computational details, but their common purpose is to predict water levels, currents and temperatures in the Great Lakes on the basis of prescribed atmospheric conditions. The period of observations dealt with in the present paper includes the passage of tropical storm Agnes during the latter part of June 1972. Data from the meteorological buoy network on Lake Ontario are combined with routine observations at first-order synoptic stations around the lake to obtain hourly values of wind-stress and pressure fields. Initial temperature distributions as a function of depth and horizontal coordinates are derived from quasi-synoptic ship cruises. Verification of model results is based on hourly values of water level data from stations on the perimeter of the lake and currents and temperatures measured by the buoy net...
