On this day in 1781, General George Washington, commanding a force of 17,000 French and Continental troops, begins the siege known as the Battle of Yorktown against British General Lord Charles Cornwallis and a contingent of 9,000 British troops at Yorktown, Virginia, in the most important battle of the Revolutionary War.
Earth's rotation causes the trade winds, in a way. If Earth didn't rotate, the wind at these latitudes would blow straight from the subtropical highs to the ITCZ.n the Northern Hemisphere, the Earth rotates counterclockwise so the wind is deflected to the right. The Southern Hemisphere rotates clockwise deflecting the wind to the left. Regardless, the Coriolis effect only influences the direction of the wind, not its speed.
Global wind patterns creates the general circulation of the atmosphere around the Earth with warm air constantly moving away from the equator toward the poles, and cold air...n the tropics wind blowing toward the equator is deflected to the right and form the northeasterly and southeasterly trade winds. Air flowing away from the high pressure over the poles is deflected to the right to form the polar easterlies. Between these two areas in the mid-latitudes are the westerly winds.
