A polar vortex, also known as a circumpolar vortex, is a wind current that circulates above the North and South Poles. The currents sit like spinning hats above the Poles. 极地涡旋,又叫环极涡旋,是环绕在南极和北极上空的一股气流,它就像一顶在极地上空不停旋转的草帽一样。
The current solutions here have spiral structure like the Ekman model, but for the strong sea state there is obvious counter wind current which almost vanishes in the weak state case. 强海况下,有明显的逆风流(WC),而在弱海况下,几乎不存在逆风流(WC)。
Accordingly, the tide wave and the wind current are studied by numerical modeling elaborately in this paper. 因此,作者着重对台湾海峡的潮波和风海流进行了模拟和研究。
In order to study the heat exchange problem in heat-harm mine, a mathematical model of heat exchange of wind current and surrounding rock is established based on the theory of the thermodynamics. 为了研究热害矿井中的气流与围岩热交换问题,基于热力学理论建立了气流与围岩热交换的数学模型,并采用METLAB对数学模型进行求解。
In this paper, investigate the main factors that affect the behavior of underwater spilled oil. Besides the property of oil, the operation pressure and the wind current, tidal current and wave have decisive effects on the oil polluted area and its position. 研究了影响水下溢油行为的主要因素,除了溢油本身的性质外,操作压力、海流、波浪、风生流等海洋环境条件对溢油污染范围和区域位置起决定性作用。
