A paper published in 1948 suggested that there was a correlation of 0.62 between the wind on Jupiter (as indicated by the motion of the Great Red Spot) and mean zonal geostrophic winds at the surface of the earth. Observations since 1948, on the other hand, indicate a correlation of −0.12, suggesting that the original correlation was spurious, even though it appeared statistically significant according to standard tests.
