On Venus, a single cell extends from the equator to the poles. On Mars, Hadley circulation is strongest in the northern winter, especially when the atmosphere is dusty, and weakest at the equinoxes, while during solstice seasons, it consists of a strong cross-equatorial surface flow with rising motion in the summer hemisphere, return flow at high altitude, and descent in mid-latitudes of the winter hemisphere.
The effect was first discussed in 1735 by the English meteorologist George Hadley (1685–1768).
