嗯,首先,空气不严格从高压到低压。例如,在[地转平衡][1]风将平行于压力梯度。方面形成这一过程被称为[锋生][2]。说它是复杂的可能是一个保守的说法。这个过程可以简化为挪威的飓风模型[3]。作为一个类比,冷空气通常是“欺负”的密度。随着冷空气的密度,它进行温暖的空气。与此同时,热空气密度较低,冷空气上升。最终冷锋赶上本身,切断热空气,导致一个锢囚锋。缺少温暖空气的中心低,额叶系统慢慢地消散。 There is a far more technical description, but for that, I would have to discuss vorticity advection, positioning of jet streak, etc. [1]: https://en.wikipedia.org/wiki/Geostrophic_current [2]: https://en.wikipedia.org/wiki/Frontogenesis [3]: https://www.weather.gov/jetstream/cyclone
