Global Winds: Trade Winds, Westerlies and Polar Easterlies - General Knowledge Today
If the winds move from west to east, they are called westerlies. If they move from The trade winds meet at the doldrums. You can visualize. This happens because Earth's rotation generates what is known as the Coriolis effect. The strongest westerlies blow through the “Roaring Forties,” a wind The place where trade winds of the two hemispheres meet is called the as the hurricane hit Barbados and other islands in the Caribbean Sea. -cause trade winds, Bands of wind caused by the uneven heating of the Earth. major global in what region do polar easterlies meet the prevailing westerlies?.
The air completes the cycle and flows back towards the equator as the trade winds.
In the northern hemisphere, the winds flow to the right and are called northeast trade winds. In the southern hemisphere the winds flow to the left and are called the southeast trade winds. This is down to the Coriolis force and friction. The Ferrel cell The Ferrel cell occurs at higher latitudes between 30 degrees and 60 degrees N and 30 degrees and 60 degrees S: Air on the surface is pulled towards the poles, forming the warm south-westerly winds in the northern hemisphere and north-westerly winds in the southern hemisphere.

These winds pick up moisture as they travel over the oceans. At around 60 degrees N and 60 degrees S, they meet cold air, which has drifted from the poles.Giuliani: 'Could Lead To Impeachment' If President Stopped Investigation - Meet The Press - NBC News
The warmer air from the tropics is lighter than the dense, cold polar air and so it rises as the two air masses meet. This uplift of air causes low pressure at the surface and the unstable weather conditions that are associated with the mid-latitude depressions.
What are the prevailing westerlies?
Much of our wet and windy weather in the UK is determined by this. The Polar cell At the poles, air is cooled and sinks towards the ground forming high pressure, this known as the Polar high.
It then flows towards the lower latitudes. At about 60 degrees N and S, the cold polar air mixes with warmer tropical air and rises upwards, creating a zone of low pressure called the subpolar low. The boundary between the warm and cold air is called the polar front.
As the temperature of the surface of the land rises, the land heats the air above it. The warm air is less dense and so it rises.
This rising air over the land lowers the sea level pressure by about 0. The cooler air above the sea, now with higher sea level pressure, flows towards the land into the lower pressure, creating a cooler breeze near the coast. The strength of the sea breeze is directly proportional to the temperature difference between the land mass and the sea. At night, the land cools off more quickly than the ocean due to differences in their specific heat values, which forces the daytime sea breeze to dissipate.
If the temperature onshore cools below the temperature offshore, the pressure over the water will be lower than that of the land, establishing a land breeze, as long as an onshore wind is not strong enough to oppose it. The wind flows towards a mountain and produces a first oscillation A.
A second wave occurs further away and higher.

The lenticular clouds form at the peak of the waves B. Over elevated surfaces, heating of the ground exceeds the heating of the surrounding air at the same altitude above sea level, creating an associated thermal low over the terrain and enhancing any lows which would have otherwise existed,   and changing the wind circulation of the region. In areas where there is rugged topography that significantly interrupts the environmental wind flow, the wind can change direction and accelerate parallel to the wind obstruction.
Jagged terrain combines to produce unpredictable flow patterns and turbulence, such as rotors. Strong updraftsdowndrafts and eddies develop as the air flows over hills and down valleys.
Wind direction changes due to the contour of the land. If there is a pass in the mountain range, winds will rush through the pass with considerable speed due to the Bernoulli principle that describes an inverse relationship between speed and pressure. The airflow can remain turbulent and erratic for some distance downwind into the flatter countryside.
