东风急流

如果大多数西风急流的,也就是说,他们从西向东吹,为什么热带/从东到西赤道急流的打击吗?

回答

你询问的能量来自太阳导致循环细胞循环?如果是这样,这是比较容易的部分。我听起来像我知道我在说什么,但我不是一个可靠的来源。但这是我的分析:太阳加热地球在赤道在陡峭的角度,提供大量的热量在赤道的空气。这空气膨胀,变得像一座山在赤道。因为山里的空气质量相同(相同数量的分子),它的重量在地面上是相同的。但事实并非如此。扩大的山空气在上面的高层大气中赤道向北泄漏下坡因为少的顶部扩大北气氛更低。但随着这个下坡下降空气北很酷的高度和时间少在太阳的直接辐射在高纬度地区因为它很酷,变得更加密集。它比空气更密集的落在北哈得来环流圈的边缘,因此沉落。 Why does it move south to complete the cycle? Because the continually rising column of air encircling the equator causes a constant low pressure condition on the ground as it rises up and spills off the mountain. If the air spills off the equatorial mountain of air, the mountain is lighter than it was before. That the mountain got high to start with would not change its weight or the pressure at the equator. The pressure at the equator is always low because the rising mountain of expanding air is forever spilling downhill to the north and causing fewer molecules and atoms of atmosphere to occupy that mountain that sits on the equator. Note, the the Polar Cell functions just like the Hadley Cell. But you might notice that the Ferrel Cell runs backwards against the dynamics I just described. That's because both the Hadley Cell and the Polar Cells are "thermally direct," or run the right way. The Ferrel cell is not run by the dynamics I just described because it is "thermally indirect," powered and supported by the boundary effects of bumping up against the Hadley and Polar Cells. I don't have a good grasp on the thermally indirect cell being driven by its neighbor cells, but I have a feeling it has to do with atmospheric lifting at the north edge of the Ferrel Cell caused by the Polar cell ( and the converse at the border with the Hadley Cell), perhaps encouraging upper atmospheric southern downhill flow, but boy that's a reach.
