Ilmanliikkeet

Ilmanliikkeet refers to movements of air, a fundamental concept in meteorology and atmospheric science. These movements are driven by differences in atmospheric pressure, which in turn are caused by uneven heating of the Earth's surface by the sun. Warmer air is less dense and rises, creating areas of lower pressure, while cooler air is denser and sinks, leading to areas of higher pressure. Air naturally flows from areas of high pressure to areas of low pressure, creating wind.

The Earth's rotation, through the Coriolis effect, further influences the direction of these air movements, causing them to deflect. This deflection results in large-scale circulation patterns in the atmosphere, such as the trade winds, westerlies, and polar easterlies. Localized ilmanliikkeet can also occur due to topographical features like mountains and valleys, or through phenomena like sea breezes and land breezes. Understanding ilmanliikkeet is crucial for weather forecasting, climate studies, and comprehending various atmospheric phenomena like storms and weather fronts.
