Climate and vegetation Other key features to consider are a mountainous climate and vegetation. The mountain climate is cooler and wetter than the plain, as the temperature drops at a rate of approximately 5 every 1 km in altitude and rainfall will increase with height, due to the so-called “screen effect”, although commonly found in mountainous areas wetter slopes (exposed to moist winds), compared with drier, in which those same winds have lost elevation and moisture tend to absorb in the soil, a phenomenon known as “foehn effect “such is the phenomenon that occurs in the Pyrenees, where the northern slope is wetter than the Spanish or South. The mountain vegetation is staggered or on floors.In the lower floors can find vegetation similar to the surrounding plain, but as you ascend hygrophilous species are appearing and more resistant to cold after the last tree species appears followed by the crag alpine meadows and even perpetual snow. The species in each of these floors and the altitude at which we can find several continents as well as with latitude is not the same as a mountainous area in sub-arctic areas in the tropics. Jamie Tisch The Rocky Mountains are a moderate amount of precipitation as rain, especially during the winter months. The meadows cover the lower levels and give way to large coniferous forests. Above wooded grasslands and shrubs extend isolated. The tops of the peaks have little vegetation and some are covered with snow and ice throughout the year.
