Why is the storm on Jupiter much stronger than storms on Earth and why don't the storms on Earth get as big as Jupiter's great red spot

Basically because Jupiter is a gas giant and thousands of times more massive than the Earth. Everything on Jupiter is on a gigantic scale. The Great Red Spot for instance could accommodate several Earths, so that explains why you couldn't have a storm on Earth which came anywhere near that size. As well as heat from the sun, which is what drives the weather on Earth, Jupiter has a massive internal source of heat.

    $\begingroup$ There are other considerations as well: Jupiter's rapid rotation (once per 10 hours or so) provided additional energy, while the lack of a solid surface removes a number of effects which tend to damp down storms on Earth after at most a few weeks. $\endgroup$ – Steve Linton Sep 13 at 12:57
  • $\begingroup$ @StephenG It's a matter of principle with Astronomy Stack users to vote me down, because they know I'm not one of them and have a completely different mind set (thank God!!). The downvoting system is wide open to abuse, which is why I never use it. $\endgroup$ – Michael Walsby Sep 13 at 14:11

    $\begingroup$ @MichaelWalsby I have voted down some of your answers myself and I think many of your answers, while well intentioned, have not been of a good standard. Nonethless this answer seems appropriate to the question to me. $\endgroup$ – StephenG Sep 14 at 2:49

    $\begingroup$ Michael, I downvote (and upvote) based on the usefulness of an answer. Many of your answers are either wrong, or aren't useful because they're personal opinion rather than providing evidence-based science, and I therefore DV them. Occasionally you post a good answer and I upvote it. This one (IMHO) doesn't deserve a vote either way: it's not wrong, but it doesn't include key details such as the ones @SteveLinton mentions. $\endgroup$ – Chappo Says Reinstate Monica Sep 15 at 2:10
