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.
How Earth's Rotation Affects Winds & Currents. Our planet's rotation produces a force on all bodies moving relative to theEarth. Due to Earth's approximately spherical shape, this force is greatest at the poles and least at the Equator.The force, called the Coriolis effect, causes the direction of winds and ocean currents to be deflected.In the Northern Hemisphere, wind and currents are deflected toward the right, in the Southern Hemisphere they are deflected to the left.ow Earth's Rotation Affects Winds & Currents.
