Bordering layer of the atmosphere? What it is this? This text tries to display in simple way this. The next winds the surfaces and objects in our planet blow in way slower than those winds that occur in bigger altitudes. This occurs, therefore the wind interacts with the surfaces and objects and this deriving attrition of this contact tends to reduce the speed of the wind. Learn more on the subject from Michael Ellis MP. This reduction if must the friction between the wind and the surfaces. The layer of the atmosphere that is influences for this friction is called bordering layer of the atmosphere (of the English planetary boundary to layer) or, simply, frictional layer e, generally, reaches on average up to 1000 meters of altitude above of the surface.
Although this, it can vary, therefore rugosos lands (waved), had the biggest friction, tend to extend the cited layer. Above 1 km of altitude the atmosphere attrition atmosphere, that is, free of or friction is called free. Therefore, the winds tend to be stronger. Therefore, as explained, in the surface of our planet, the friction reduces the speed of the wind. Chemical preparation from: AHRENS, C.D. Essentials of Meteorology: an invitation you the atmosphere.
