hypothetically, if incoming and outgoing radiation balanced at every point on earth, would there still be air circulation? What do you think?
Integral said:Since the incoming and outgoing radiation balance, and since we have air currents the only possible answer is, yes.
matthyaouw said:(snip) This is what drives the major atmospheric currents. (snip)
The primary cause of air circulation on Earth is the uneven heating of the Earth's surface by the sun. This creates differences in air temperature and pressure, which in turn leads to the movement of air from high pressure areas to low pressure areas.
Air circulation plays a crucial role in weather patterns. The movement of air masses, such as warm and cold fronts, can cause changes in temperature, precipitation, and wind patterns. It also helps distribute moisture and heat around the globe, influencing climate patterns.
The three major global wind patterns are the trade winds, the westerlies, and the polar easterlies. The trade winds blow from east to west near the equator, the westerlies blow from west to east in the middle latitudes, and the polar easterlies blow from east to west near the poles.
Air circulation can impact air pollution and air quality in a few ways. It can help disperse pollutants and bring in cleaner air from other regions. However, it can also trap pollutants in certain areas, causing poor air quality. Additionally, certain wind patterns can transport pollutants long distances.
Human activity, such as the burning of fossil fuels and deforestation, can contribute to changes in air circulation patterns. These activities can release pollutants into the air, which can affect air pressure and wind patterns. Climate change caused by human activity can also lead to shifts in air circulation patterns, potentially affecting weather patterns and air quality.
