Hadley cells
The circulation pattern cells near the equator are the Hadley cells. These cells involve warm air rising near the equator, moving towards the poles at upper levels of the atmosphere, cooling and sinking around 30 degrees latitude, and returning towards the equator near the surface. This creates a continuous loop of air movement in the tropical regions.
The Earth's actual atmospheric circulation pattern is more complex due to factors such as the Coriolis effect, distribution of land and water, and varying heat absorption and release by the Earth's surface. These factors influence the development of global wind patterns, which lead to the formation of multiple cells of atmospheric circulation, like the Hadley, Ferrel, and Polar cells. This complexity results in a more intricate circulation pattern than a simple rising at the equator and sinking at the poles model.
Hadley cells
The pair of air circulation cells located on each side of the equator are called Hadley cells. These cells play a crucial role in redistributing heat from the equator to higher latitudes, influencing global climate patterns.
it can produce convection current in the atmosphere
This process creates global atmospheric circulation patterns known as Hadley cells at the equator and polar cells at the poles. These circulation patterns play a key role in redistributing heat around the Earth and influencing weather patterns.
Global air circulation between the equator and the poles is primarily driven by the uneven heating of the Earth's surface by the Sun. The equator receives more direct sunlight, causing warmer air to rise, while cooler air at the poles sinks. This creates a circulation pattern known as the Hadley, Ferrel, and Polar cells, which redistribute heat and moisture around the planet. Additionally, the Coriolis effect, caused by the Earth's rotation, influences wind direction and contributes to the complex patterns of global air circulation.
The type of storm that is characterized as a circulation cell is a tornado. Circulation cells are large areas of movement created by the rotation of the earth and the transfer of heat from the equator toward the poles.
There are three main atmospheric circulation cells in each hemisphere: the Hadley cell, the Ferrel cell, and the Polar cell. This results in a total of six cells globally. The Hadley cells are located near the equator, the Ferrel cells are situated between the Hadley and Polar cells, and the Polar cells are found near the poles. These circulation patterns play a crucial role in determining climate and weather patterns around the world.
These looping patterns of air flow are called Hadley cells near the equator, Ferrel cells in the mid-latitudes, and Polar cells near the poles. This atmospheric circulation helps redistribute heat and moisture around the Earth.
