Hadley cell

[′had·lē ‚sel]
(meteorology)
A direct, thermally driven, and zonally symmetric circulation first proposed by George Hadley as an explanation for the trade winds; it consists of the equatorward movement of the trade winds between about latitude 30° and the equator in each hemisphere, with rising wind components near the equator, poleward flow aloft, and finally descending components at about latitude 30° again.

It is possibly linked to the expansion of the Hadley cell.

A similar pattern, called a Hadley cell, carries warm, moist air from Earth's tropics to the cooler middle latitudes.
This creates a Hadley cell from the equator to about 30 degrees north latitude (in North America this cuts through the three most southern states, at the neck of Florida, Louisiana at New Orleans, and Texas at about Houston).
Laying near 30 degrees north the UAE is directly under the sub-tropical [jet stream convergence zone] anticyclone, known as low-altitude or the Hadley cell.
This expansion of the Hadley cell in turn impels tropical air currents to push high-altitude clouds poleward.
