Frontogenesis is the fluid-dynamical processes that rapidly sharpen horizontal density gradients and their associated horizontal velocity shears. It is a positive feedback process where the ageostrophic, overturning secondary circulation in the cross-front plane accelerates the frontal sharpening until an arrest occurs through frontal instability and other forms of turbulent mixing. Several well-known types of oceanic frontal phenomena are surveyed, their impacts on oceanic system functioning are assessed, and future research is envisioned.

海洋锋生

前生是迅速使水平密度梯度及其相关的水平速度剪切变陡的流体动力学过程。这是一个积极的反馈过程,在交叉前平面中,颠倒性的,颠覆性的二次循环加速了额叶锐化,直到由于额叶不稳定性和其他形式的湍流混合而停滞。对几种著名的海洋锋面现象进行了调查,评估了它们对海洋系统功能的影响,并展望了未来的研究。
