- An important factor in our weather patterns is the “Coriolis Effect”. This phenomenon causes the winds at the equator to blow toward the west (opposite the direction of the earth’s spin at the equator). The winds loop around and blow from west to east at 30 degrees north and south of the equator.

The Coriolis Force & Global Wind Systems The Environmental Literacy Council. The Coriolis Force & Global Wind Systems. The air in the Earth’s atmosphere moves from high pressure to low pressure. On a rotating body such as the Earth, the air turns to the right—counterclockwise—in the Northern Hemisphere and to the left—clockwise—in the Southern Hemisphere.

How Does Earth's Spinning Affect Wind And Ocean Patterns? If Earth did not rotate on its axis, winds would blow from the north toward the south and from the south toward the north. A straight line, as drawn from the equator towards the north pole or from the north pole to the equator, as indicated in the example to the left, models this kind of wind direction.

- The faster air move, the higher the Coriolis force, bending the wind more and more to its right. Eventually, at 5, the two forces cancel each other and the wind flow in a straight line parallel to isobars.

earth science Winds curve because of the Earth’s rotation. Ocean currents curve clockwise in the northern hemisphere, and counterclockwise in the southern hemisphere. The movement of a pendulum. It does not actually move, it is the Earth moving that causes the pendulum to appear to change the direction of its swing. Night and Day What causes night and day? The rotation of the Earth The side of the Earth that is facing the sun has daylight, the side of the Earth away from the sun has night. It takes 24 hours for the Earth to complete one rotation. The Earth is tilted on it’s axis at a 23.5 degree angle.

- Trade Winds. In the Northern Hemisphere, warm air around the equator rises and flows north toward the pole. As the air moves away from the equator, the Coriolis effect deflects it toward the right. It cools and descends near 30 degrees North latitude. The descending air blows from the northeast to the southwest, back toward the equator (Ross, 1995). A similar wind pattern occurs in the Southern Hemisphere; these winds blow from the southeast toward the northwest and descend near 30 degrees South latitude. These prevailing winds, known as the trade winds, meet at the Intertropical Convergence Zone (also called the doldrums) between 5 degrees North and 5 degrees South latitude, where the winds are calm. The remaining air (air that does not descend at 30 degrees North or South latitude) continues toward the poles and is known as the westerly winds, or westerlies. The trade winds are so named because ships have historically taken advantage of them to aid their journies between Europe and the Americas (Bowditch, 1995).

Unit 6: Local and General Winds Cold fronts are much more common and may be spaced from 1 day to 2 weeks apart. Remember, winds always shift clockwise in direction with the passage of a weather front. They increase in velocity as the fronts pass through an area, and their consistency, strength, and gustiness may vary greatly.ind direction is always the direction from which the wind is blowing. As such fronts move through a region, the winds will shift in a clockwise direction. Ahead of a warm front, winds will be out of the northeast and east. Winds ahead of a cold front usually shift from southeast to south, to southwest.

- Earth's rotation is the rotation of the planet Earth around its own axis.The Earth rotates from the west towards east. As viewed from North Star or polestar Polaris, the Earth turns counter-clockwise.arth's movement along its nearly circular orbit while it is rotating once around its axis requires that Earth rotate slightly more than once relative to the fixed stars before the mean Sun can pass overhead again, even though it rotates only once (360°) relative to the mean Sun.

Coriolis effect The Earth's rotation means that we experience an apparent force known as the Coriolis force. This deflects the direction of the wind to the right in the northern hemisphere and to the left in the southern hemisphere.his is similar to what happens in the northern hemisphere of the Earth, where winds are deflected to the right. This deflection is a major factor in explaining why winds blow anticlockwise around low pressure and clockwise around high pressure in the northern hemisphere and visa versa in the southern hemisphere.

Global Wind Patterns Also as elevation or altitude increases, air becomes less dense. Unequal heating of the Earth’s surface also forms large global wind patterns. In area near the equator, the sun is almost directly overhead for most of the year. Warm air rises at the equator and moves toward the poles.At the poles, the cooler air sinks and moves back toward the equator. However, it is not this simple. Global winds do not move directly from north to south or south to north because the Earth rotates.rade Winds – About 30° north and south of the equator, the warm, moist air that rose vertically cools and begins to sink. Here the sky is clear. There are few clouds and little rainfall. Winds are calm.

Is the Earth an Electromagnetic Coil, Step up or down Transformer? The Earths Magnetic North Pole is, at the moment, about 11 degrees away from the geographical axis of the Earth and means that the Magnetic axis and the Geographical axis are at a slight angle. The Earths Jet Streams are normally very strong and fast ‘rivers of energised air’ flowing around the Earth.

The Coriolis Force & Global Wind Systems The rotation creates friction, called the coriolis force, between the air and the Earth’s surface which breaks up the air circulation between the equator and the poles into three different mirror-image wind systems on each side of the Equator.

If a hurricane rotates in one direction and a cyclone rotates in the other, what happens if they cross the equator? They won't! Imagine a moving conveyor belt (the equator) with guide wheels in contact with it above and below (hurricanes/cyclones). The guide wheels above the conveyor belt rotate in an opposite direction to the wheels below.

- Remember winds are identified by the direction they are coming from not heading to!). As the Earth does continue to rotate at a constant rate, and the winds do continue, the transfer of momentum between Earth/atmosphere/Earth must be in balance; and the angular velocity of the system maintained.he sea breeze is most common along tropical coasts, being felt on about 3 out of 4 days. The warmer temperatures, increased solar radiation and generally weaker prevailing winds in the low latitudes promote the development of the sea breeze.

- A storm's rotation is due to something called the Coriolis effect, which is a phenomenon that causes fluids like water and air to curve as they travel across or above Earth's surface.Here's the basic idea: Earth is constantly spinning around its axis from west to east.he air keeps trying to make its way to the middle, and keeps getting deflected, causing the entire system to spin in a counterclockwise direction. In the Southern Hemisphere, where the Coriolis effect pulls air to the left, the opposite happens: storms spin around the eye in a clockwise manner.

- If the Earth did not spin on its axis, this cycle of evaporation, condensation, and precipitation would move water and air along a north-south axis from the equator to the poles. This, however, does not happen. Earth's spin creates three belts of circulation (Figure 2).

Factors That Affect Wind: Pressure Gradient Forces, Coriolis Effect & Friction Winds don't blow directly north or south. The movement of wind is  affected by the rotation of the Earth. The Earth's rotation causes  wind to travel in a curved path rather … than a straight line. The  curving of moving objects, such as wind, by the Earth's rotation is  called the Coriolis Effect.

- If the Earth’s axis of rotation were vertical with respect to the path of its orbit around the Sun, the size of the heating imbalance between equator and the poles would be the same year round, and the seasons we experience would not occur. Instead Earth’s axis is tilted off vertical by about 23 degrees.

- Cold heavy air flows south from the north pole and is bent west, forming the polar easterlies. Warm air rises at the equator drawing air from the north which bends to the west, contributing to the trade winds. The Coriolis effect bends the westerlies and trade winds slightly clockwise in the northern hemisphere.

- These winds are often grouped together as trade winds, easterlies, and westerlies. Trade winds - Trade winds occur near the equator and flow from either the north or south towards the equator. They curve towards the west due to the spin of the Earth.

- The Coriolis effect helps explain the paths of winds in the atmosphere. In the Southern Hemisphere, winds pass from high-pressure systems to low-pressure systems on the left. This makes storms, such as Cyclone Ingrid, storming across northern Australia above, appear to swirl in a clockwise direction.
