The descended air then travels toward the equator along the surface, replacing the air that rose from the equatorial zone, closing the loop of the Hadley cell. [3] The poleward movement of the air in the upper part of the troposphere deviates toward the east, caused by the coriolis acceleration. At the ground level, however, the movement of the ...
In this process the warm air is cooled; it gains density and falls towards the earth and the cell repeats the cycle. Convection cells can form in any fluid, including the Earth's atmosphere (where they are called Hadley cells ), boiling water, soup (where the cells can be identified by the particles they transport, such as grains of rice), the ...
In nature, convection cells formed from air raising above sunlight-warmed land or water are a major feature of all weather systems. Convection is also seen in the rising plume of hot air from fire, plate tectonics, oceanic currents (thermohaline circulation) and sea-wind formation (where upward convection is also modified by Coriolis forces ...
For example, when a machine (not a part of the system) lifts a system upwards, some energy is transferred from the machine to the system. The system's energy increases as work is done on the system and in this particular case, the energy increase of the system is manifested as an increase in the system's gravitational potential energy. Work ...
Meridional circulation cells are a large-scale atmospheric motion where gas rises at a certain latitude, travel in the north-south (meridional) direction, descends, and get back to the origin in a closed cell circulation. [38] On Earth, the meridional circulation is composed of 3 cells in each hemisphere: Hadley, Ferrel and Polar cells.

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) above the Earth's surface, cooling and descending in the subtropics at around 25 degrees latitude, and then returning ...
