Polar, Ferrell, and Hadley cells are ____________ that circulate ____________ around the globe. These cells also create ________
____ that move over Earth’s surface. Where the cells meet, ____________ develop, which are fast moving corridors of air that influence weather patterns.
While the Polar and Hadley cells are strictly closed-loop convection cells, the Ferrell cells are not completely closed. Together these three types of cells represent atmosphere circulation and are responsible for distributing heat and moisture around the planet. Warm air is transported from the Tropics to the polar regions and cold air is pushed southward.
The Polar cell is made up of frigid air due to low solar heating and is therefore denser. the Hadley cells converge at the equator to form the Intertropical Convergence Zone. the Mid-latitude Ferrell cells are the most unstable and experience the most windy conditions. Their exact location wanders throughout the course of the year.
