    Third, the thermal wind balance holds for the circulation (Vallis, 2006). For simplicity, the model is also symmetric around the equator. These initial assumptions make the explanation of Hadley Cell dynamics much simpler. Angular momentum is defined as the cross product of a particle's distance from the axis of rotation, r, and the particle's

  • Wind circulation on the Earth - Eniscuola

    May 13, 2013 · Wind circulation on the Earth. Air masses are moved by solar heating and in particular by the difference in temperature (gradient) between equatorial and tropical areas. Solar radiation in equatorial areas is more intense than in tropical areas. Tropical air, warmer and less dense, tends to go up attracting cold air from tropical areas.

    As a result, the movement of air in the polar cell circulation produces the polar easterlies. In the circulation cell that exists between 60° and 30° north, the movement of air produces the prevailing westerlies. In the tropic circulation cell, the northeast trade winds are produced. These are the so-called permanent wind systems of the each.

  • Lab 4: It's All Connected: Global Circulation

    Apr 15, 2021 · The global circulation of air drives some of the Earth's ocean currents and helps to redistribute the solar energy that reaches Earth, moderating climate and impacting environments for all life on Earth. Without that circulation and redistribution of solar energy, the equatorial regions would be hotter and the polar regions colder.
