Hadley cells are most commonly identified using the mass-weighted, zonally-averaged streamfunction of meridional winds, but they can also be identified by other measurable or derivable physical parameters such as velocity potential or the vertical component of wind at a particular pressure level. See more The Hadley cell, also known as the Hadley circulation, is a global-scale tropical atmospheric circulation that features air rising near the equator, flowing poleward near the tropopause at a height of 12–15 km (7.5–9.3 mi) … See more The broad structure and mechanism of the Hadley circulation – comprising convective cells moving air due to temperature differences in a … See more Natural variability Paleoclimate reconstructions of trade winds and rainfall patterns suggest that the Hadley circulation changed in response to See more • Polar vortex – a broad semi-permanent region of cold, cyclonically-rotating air encircling Earth's poles • Brewer–Dobson circulation – a circulation between the tropical troposphere and the stratosophere See more The Hadley circulation describes the broad, thermally direct, and meridional overturning of air within the troposphere over the low latitudes. Within the global atmospheric circulation See more The Hadley circulation is one of the most important influences on global climate and planetary habitability, as well as an important … See more Outside of Earth, any thermally direct circulation that circulates air meridionally across planetary-scale gradients of insolation may be described as a Hadley circulation. A terrestrial atmosphere subject to excess equatorial heating tends to maintain an … See more WebThe Ferrel cells are found between the Hadley and Polar cells. Cold air sinks near 30° and rises near 60°. The air at the Earth's surface flows northwards and is affected by the …
