12.2 Wind
![Winds are formed, as air flows from an area of high pressure to an area of low pressure. Low pressure forms when air warmed by the Sun rises up.](https://peda.net/oppimateriaalit/e-oppi/verkkokauppa/yl%C3%A4koulu/lukuvuosi-20-21/englannin-kieliset/geography/emaantieto_a22/13-s%C3%A4%C3%A4-suvi/tuulen-synty/k:file/photo/272d346122408cf6dae68be8a2aefb6f7cd336b6/high-low-pressure-taitto.png)
Winds are formed when air flows from an area of high pressure to an area of low pressure.
Some winds are temporary, wheras some are constant. Constant winds are known as planetary winds. Examples of planetary winds include the European west wind, as well as trade winds that flow near the planet's equator.
