This is the best summary I could come up with:
The planet Jupiter is particularly known for its so-called Great Red Spot, a swirling vortex in the gas giant's atmosphere that has been around since at least 1831.
In 1610, aided by the emergence of telescopes, Galileo Galilei famously observed Jupiter's four largest moons, thereby bolstering the Copernican heliocentric model of the solar system.
A pharmacist named Heinrich Schwabe made the earliest known drawing of the Red Spot in 1831, and by 1878 it was once again quite prominent in observations of Jupiter, fading again in 1883 and at the onset of the 20th century.
Sánchez-Lavega and his co-authors set out to answer this question, combing through historical sources—including Cassini's notes and drawings from the 17th century—and more recent astronomical observations and quantifying the results.
The team also performed multiple numerical computer simulations testing different models for vortex behavior in Jupiter's atmosphere that are the likely cause of the Great Red Spot.
The numerical simulations ruled out the merging vortices model for the spot's formation; it is much more likely that it's due to wind currents producing an elongated atmospheric shell.
