What is the mass of Jupiter's white oval storms compared to Earth?

[Iustitia]

I know the Great Red Spot on Jupiter is much larger than the white ovals. However I'm curious as to how much mass the white oval storms would have compared to say the Earth. I know they're ovals and from what I've seen they're about 9,000 km long and 5,000 km wide which if I paid attention means it should have a diameter of about 7280 km.

I know several Earths could fit in the Red Spot, but since Earth has a diameter of 12,742 km it's be too large to fit in the white storms. But I don't know the third dimension of jovial storms. How high do storms extend through the atmosphere of Jupiter?

Also, what would the mass of these storms be? Is it safe to say they'd have much less mass than a rocky planet like Earth as Jupiter is a gas giant and its storms are composed and gases?

Thanks. I know this is an odd topic.

This article on the atmosphere of Jupiter discusses its structure:

IDK how you would calculate the mass of a storm on earth, let alone one on a planet some hundreds of millions of miles from earth.

In any event, in recent years, the Great Red Spot has been shrinking.
