对黄海暖流形成机理的分析表明，压强梯度力、垂向摩擦力和柯氏力占主要地位。
It is shown from the analysis of formation mechanism that the pressure gradient force , vertically frictional force and Coriolis force play the leading roles in forming the YSWC .

但在地形变化剧烈，尤其在密度层结效应明显的海域，σ坐标模式中的水平压强梯度力误差会引起伪密度流。
However , the horizontal pressure gradient force estimation is problematic over steep topography and density stratification areas in sigma coordinate model . The artificial pressure gradient error may create artificial flow .
