Wind action is a key physical-chemical factor, meaning that turbidity is often high (and variable), there is great exchange between the water and the sediments, the water temperatures closely follow that of the air (with little or no thermal stratification), oxygen concentration is close to saturation, and the supply of nutrients borne by the wind (
anemotrophy) and from the clay of the sediments (argillotrophy) have a significant impact on the bodies of water.
