【摘要】 文中介绍了对旋转系统中侵入型异重流特征的若干实验室观察结果,在Coriolis力作用下,异重流取沿岸(壁)流形式,其宽度与其Rossby变形半径成比例,在实验的参数范围内,这种沿岸流均为不稳定的,在其演化过程中产生出气旋——反气旋涡对,乃至与岸壁分离与再附的大弯曲,本文还初步考察了波长、相对厚度与Frou de数之间的关系。更多还原

【Abstract】 Some laboratory experiments on intrusive gravity currents in rotating fluids are described. The following was observed. The currents took the form of coastal currents, whose widths were a constant fraction of corresponding Rossby deformation radii: for tested conditions, the currents were unstable producing eddy pairs and even detachment from the wall during evolution. Wave length-depth ratio-Froude number relationship was examined.更多还原
