应用改进的方法计算的通风气流矢量与热带气旋移动矢量相关密切。

The correlation between the ventilation flow vector calculated applying the improved method and the motion vector of tropical cyclone is very close.

这或许看上去跟直觉不大一样，某物在移动，但在那时刻，它是静止的，现在看到，这就是那矢量，这很有用。

So, that's especially maybe a counter intuitive thing, but something is moving. And at that time, it's actually stopped. Now, let's see, so that's the vector. And, it's useful.

所以记住移动的量△,约等于v*△,这是用速度矢量的定义。

r So, let's remember that the amount by which we moved, t delta r, is approximately equal to v times delta t, OK, and just using the definition of a velocity vector.
