Here's a breakdown:

* The Great Red Spot: This iconic storm has been raging for at least 400 years, and possibly much longer. It's a massive storm system bigger than Earth, with winds reaching over 400 mph.

* Other Storms: While not as long-lasting as the Great Red Spot, other storms on Jupiter can persist for months or even years. This is due to Jupiter's strong atmospheric circulation and lack of solid surface to disrupt them.

* Smaller Storms: Smaller storms are also common on Jupiter, and these can last for days or weeks.

It's important to note that Jupiter's atmosphere is incredibly dynamic, and new storms can form and old ones can dissipate at any time. The exact duration of a storm depends on factors like its size, intensity, and location within the Jovian atmosphere.
