    Drift
In summary, "drift" when discussing the Great Red Spot on Jupiter refers to the speed at which the spot is moving within its designated belt or zone. This speed is different from the overall speed of the belt or zone itself. Recent observations have shown that the Great Red Spot is shrinking in length, but growing in height and drifting westward at a rate of 2 degrees per month. This information can be further explored through the provided articles and calculator.

Can someone explain to me what "drift" is when talking about the rate at which the grs drifts around Jupiter?

I have read several articles that talk about how the "drift rate" is changing. Is this the speed the spot is moving in the belt or zone it lays in? That is a different speed than the belt or the zone, right?

Thanks.

This article may answer your question on drift as well as other questions on the Great Red Spot.

Apparently, its been getting smaller, taller and drifting westward.

and a calculator for the drift at 2 degrees per month:

What is the Drift Rate of Jupiter's Great Red Spot?

The drift rate of Jupiter's Great Red Spot refers to the speed at which the storm is moving across the surface of the planet. This is measured in degrees of longitude per day.

Why is the Drift Rate of Jupiter's Great Red Spot important to study?

Studying the drift rate of Jupiter's Great Red Spot can provide insight into the atmospheric conditions and dynamics of the planet. This information can also help us understand the longevity of the storm and how it may change over time.

How is the Drift Rate of Jupiter's Great Red Spot measured?

The drift rate is measured using images taken by spacecraft or ground-based telescopes. By tracking the storm's movement over time, scientists can calculate its drift rate.

What is the current Drift Rate of Jupiter's Great Red Spot?

As of 2020, the drift rate of Jupiter's Great Red Spot is approximately 0.33 degrees of longitude per day. This is equivalent to about 13 miles per day.

Has the Drift Rate of Jupiter's Great Red Spot changed over time?

Yes, the drift rate has been observed to change over time. In the 19th and 20th centuries, the storm's drift rate was slower, but it has been increasing in recent years. However, there is still much debate and research being conducted on the reasons for this change.
