which way the wind blows

The earth has uneven heating beacuse of the tilt of the axis and the rotation which is spins. If the sun is shining directly on the earth it is hotter than when the sun is angled on the earth. In class we had a globe and a flashlight to demonstrate this drill. We held the flashlight above the globe and saw the light is showed when it was directly on the earth and when it was angled on the earth. I learned that direct sunlgiht is hotter. The earths rotation effects the air and water masses by spreading it out. In class we had a circle piece of paper on a pencil. We had to spin it around the pencil while our partner drops water on it. After doing this the water whirled out toward the sides. This showed how the air and water masses act while the earth rotates. The Hadley cell, named after George Hadley, is a tropical atmospheric circulation that is defined by the average over longitude, which features rising motion near the equator, poleward flow 10–15 kilometers above the surface, descending motion in the subtropics, and equatorward flow near the surface. This circulation is intimately related to the trade winds, tropical rainbelts & hurricanes, subtropical deserts and the jet streams.Coriolis effect is a deflection of moving objects when they are viewed in a rotating reference frame. In a reference frame with clockwise rotation, the deflection is to the left of the motion of the object; in one with counter-clockwise rotation, the deflection is to the right. Although recognized previously by others, the mathematical expression for the Coriolis force appeared in an 1835 paper by French scientist Gaspard-Gustave Coriolis, in connection with the theory of water wheels. Early in the 20th century, the term Coriolis force began to be used in connection with meteorology. The last activity we had a map of the world and we had to draw all different kinds of winds. The trade winds (also called trades) are the prevailing pattern of easterly surface winds found in the tropics, within the lower portion of the Earth's atmosphere, in the lower section of the troposphere near the Earth's equator.[1] The trade winds blow predominantly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere, strengthening during the winter and when the Arctic oscillation is in its warm phase.doldrums is a colloquial expression derived from historical maritime usage, in which it refers to those parts of the Atlantic Ocean and the Pacific Ocean affected by the Intertropical Convergence Zone, a low-pressure area around the equator where the prevailing winds are calm. The low pressure is caused by the heat at the equator, which makes the air rise and travel north and south high in the atmosphere, until it subsides again in the horse latitudes. Some of that air returns to the doldrums through the trade winds. This process can lead to light or variable winds and more severe weather, in the form of squalls, thunderstorms and hurricanes.The Westerlies, anti-trades,[1] or Prevailing Westerlies, are prevailing winds in the middle latitudes between 30 and 60 degrees latitude, blowing from the high pressure area in the horse latitudes towards the poles. These prevailing winds blow from the west to the east[2] and steer extratropical cyclones in this general manner. Tropical cyclones which cross the subtropical ridge axis into the Westerlies recurve due to the increased westerly flow. The winds are predominantly from the southwest in the Northern Hemisphere and from the northwest in the Southern Hemisphere.
