Constant heating from the sun causes air to rise, then flow away from the equator. Sinking air in the subtropics spreads out and some of it flows toward the equator. This creates a "cell" (Hadley Cell) of circulation that constantly generates rising air at the equator and therefore low pressure.
What else can I help you with?
What causes the low pressures region that prevails over the tropics?
The low pressure region that prevails over the tropics is caused by the radiating heat from the sun. This area gets heat from the sun that is most directly overhead and the intense heat of the day and cool of night cause low pressure.
What causes the low pressure region that Prevails over the tropics?
Constant heating from the sun causes air to rise, then flow away from the equator. Sinking air in the subtropics spreads out and some of it flows toward the equator. This creates a "cell" (Hadley Cell) of circulation that constantly generates rising air at the equator and therefore low pressure.
Why are the tropics ware and sunny year round?
The tropics receive more direct sunlight as they are closer to the equator, leading to consistent warmth and sunlight year-round. The Earth's tilt also causes the tropics to experience less seasonal variation in temperature and daylight hours compared to regions further from the equator.
How does air move from low pressure to high pressure?
Air moves from areas of high pressure to low pressure due to the pressure gradient force. This force causes air to flow from regions of higher pressure to regions of lower pressure in order to equalize the pressure differences.
Why there are only 2 seasons in the tropics?
The tropics experience only two seasons, wet and dry, due to the consistent positioning of the sun directly overhead, which results in consistently warm temperatures and a stable climate. This causes the tilt of the Earth's axis to have less of an impact on creating distinct seasons as it does in other regions.
Why is it hotter around the tropics?
The tropics receive more direct sunlight throughout the year compared to other regions because they are positioned near the equator. This intense sunlight causes greater heating of the surface, leading to hotter temperatures in tropical areas.
what main factors cause the air in earths atmosphere to move?
uneven heating by the sun causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.
What are the causes of abnormal pressure in a well?
causes of abnormal pressure
Why do and breezes occur?
Convection currents cause the air to rise when heated. This causes the air pressure to become lower on the surface, which then pulls in air from nearby regions, which is felt as wind.
Which pressure is in excess and causes fluids to move from A to C?
Through oncotic pressure the body is able to hold water in the bloodstream. If this excess in pressure decreases, from conditions like liver disease, water will leak into surrounding organs and tissues preventing it from moving from point a to point c.
The pressure gradient force causes air to flow from areas of relatively pressure to areas of relatively pressure?
The pressure gradient force is responsible for initiating horizontal air movement from high pressure to low pressure areas. This force is a result of pressure differences between two adjacent regions, leading to the flow of air in an attempt to equalize the pressure.
What causes cavitatation in pipelines?
Cavitation is caused by low pressure. Regions of low pressure in pipes can be caused by sharp curvatures (such as 90 degree bends), sediment or residues, restrictions to flow such as throttling valves, measurement equipment, etc.
