Question

what are hadely cells

Answer 1

In the Hadley cell, air rises up into the atmosphere at or near the equator, flows toward the poles above the surface of the Earth, returns to the Earth's surface in the subtropics, and flows back towards the equator. This flow of air occurs because the Sun heats air at the Earth's surface near the equator

Hadley Cells are the low-latitude overturning circulations that have air rising at the equator and air sinking at roughly 30° latitude. They are responsible for the trade winds in the Tropics and control low-latitude weather patterns. ... First, the Hadley Cell circulation is constant.

Answer 2

A large scale atmospheric convection cell in which air rises at the equator and sinks at medium latitudes, typically about 30° north or south.

Thr Hadley cell, named after George Hadley, is a global scale tropical atmospheric circulation that features air rising near the Equator, flowing poleward at 10–15 kilometers above the surface, descending in the subtropics, and then returning equatorward near the surface. This circulation creates the trade winds, tropical rain-belts and hurricanes, subtropical deserts and the jet streams.


In each hemisphere, there is one primary circulation cell known as a Hadley cell and two secondary circulation cells at higher latitudes; between 30° and 60° latitude known as the Ferrel cell and beyond 60° as the Polar cell. Each Hadley cell operates between zero and 30 to 40 degrees north and south and is mainly responsible for the weather in the equatorial regions of the world.
