    I’m guessing it’s because they rotate in different direction in the northern and Southern hemisphere.

    So crossing would imply switching direction, which would require to put that energy “somewhere” and it’s physically not possible.

      No. It’s because the earth spins faster there. Them turning a certain direction is a result, not a cause.

        A) The Earth spins at the same speed. What you are talking about is the tangential speed.

        B) The tangential speed is not much faster at the equator than 100km South or North of it.

        C) The speed difference would not explain why they don’t cross the equator. It may explain (partially) why there are no hurricanes further away from the equator.

          I love it when people use bulletpoints to seem smart when they are so confidently wrong

              For someone being so hyper pedantic you failed to realize they didn’t use anything even close to bullet points.

                Wow! Tough crowd. Seriously, at least I explained my reasoning for why hurricanes do not cross the equator. All they did was make either wrong or poorly formulated claims without any kind of explanation, and then throw insults.

                Saying that “The Earth spins faster” makes no sense, especially in this context: why would the equator spin significantly faster than 100km away from it?!? And why would this negligible speed difference prevent hurricane from crossing that line?

                If you want to correct someone, at least do it right.
