摘要对湖泊风混合过程的时间尺度分析表明，根据描述风强度、流域大小和分层的参数的相对大小，湖泊对风的响应可分为四种温跃层加深行为。的依赖性描述的混合层理查森数和混合层的厚度与长度的纵横比。分类是用来解释的多样性的现象，在文献中报道的风事件在一些不同的湖泊和实验室的坦克，无论是足够短或足够窄的旋转效果是不重要的。的分类是根据一个两层，矩形盆地在没有科氏力和表面加热。该分类扩展在一个简单的方式，以更现实的分层和盆地形状预测风事件的整体混合功能。对风的反应各不相同，从...
Abstract An analysis of the time scales of processes relevant to wind mixing in lakes indicates that the response of a lake to wind may be classified into four regimes with respect to thermocline deepening behavior, depending on the relative sizes of the parameters describing wind strength, basin size and stratification. The dependence is described in terms of a mixed layer Richardson number and the aspect ratio of the mixed layer thickness to length. The classification is used to explain the diversity of phenomena reported in the literature for wind events in a number of different lakes and laboratory tanks which are either short enough or narrow enough for rotational effects to be unimportant. The classification is derived with reference to a two-layer, rectangular basin in the absence of Coriolis forces and surface heating. The classification is exended in a simple way to more realistic stratifications and basin shapes to predict the overall mixing features of a wind event. Response to wind varies from...
