Two belts of trade winds encircle the earth, blowing from the tropical high-pressure belts to the low-pressure zone at the equator. ITCZ. Intertropical Convergence Zone is a belt of low pressure which circles the Earth generally near the equator where the trade winds of the Northern and Southern Hemispheres come together. Easterlies.

The low pressure center located near the Aleutian Islands on mean charts of sea level pressure. It represents one of the main centers of action in the atmospheric circulation of the Northern Hemisphere. The Aleutian low is most intense in the winter months; in summer it is displaced toward the North Pole and is almost nonexistent.

The 3-cell model assumes that the earth is of uniform composition and not tilted toward or away from the sun. It predicts belts of high pressure at 30 N and 30 S latitude as shown above at left . Because the real world has oceans and continents we find centers of high pressure, not belts, located near 30 latitude.

· Answer: Pressure systems and wind movement are closely interconnected. Differences in atmospheric pressure create pressure gradients, causing air to move from high-pressure areas to low-pressure areas. Winds result from the Earth’s attempt to balance these pressure differences. In high-pressure systems, air descends
Consulta
· At 60 degrees latitude, the air pressure is generally low. This is because of the convergence of warm and cold air, which causes the warm air to rise, resulting in low air pressure. It is part of the subpolar low pressure belt and is the result of the warm air from the equator and the cold air from the poles being unable to mix well.

Atmospheric pressure is one of the crucial controlling factors of Earth's weather and climate. Atmospheric pressure is an important weather indicator. High-pressure systems generally result in fair and calm weather. Atmospheric pressure supports sunny, clear, and pleasant weather, whereas higher levels favour wet and overcast weather.

· Pressure belts. Pressure belts refer to the global patterns of atmospheric pressure that exist on Earth's surface. These belts are formed due to the distribution of solar energy received by different regions and the rotation of the Earth. Understanding pressure belts is crucial in comprehending global weather patterns and the movement

Another common low pressure zone is the Subpolar Low, which exists around the latitudes of 60 to 70 degrees. It is formed due to the collision of cold polar air and warm subtropical air masses. The temperature difference between these two air masses causes the warmer air to rise, creating a low pressure area.

· The Equatorial Low-Pressure Belt is positioned between 0°N to 5°N and 0°S to 5°S. It is characterised by high temperatures, causing the air in this area to warm, expand, and subsequently ascend, creating a region of low pressure. Winds originating from the subtropical high-pressure belt travel towards the equatorial low-pressure belt.

· The Polar High Pressure Belts are small in area, that lie around the Poles between 80º -90ºN and S latitudes. These regions are the realm of extreme cold and are remarkably characterized by permanent IceCaps. The intense cold makes the polar air extremely cold and dense. This cold and heavy air tends to settle near the ground.

The subpolar low pressure belt is found at 60 latitude. This is also a convergence zone where the cold polar easterly winds and the warmer prevailing westerly winds meet. The boundary between these two different kinds of air is called the polar front and is often drawn as a stationary front on weather maps.
