The climate of the savannah

Savannah is a sea of ​​grass with islands of trees,which have umbrella crowns. Huge areas of these natural communities are located in Africa, South America, Australia and India. A distinctive feature of savannas is the alternation of wet and dry seasons, which take about half a year, changing one another. Everyone knows that for tropical and subtropical latitudes, in which savannas are located, the change in two air masses is typical - dry tropical and moist equatorial.

Also, a significant impact on the climate of the savannahhave monsoon winds that bring seasonal rains. Since these landscapes are located between dry desert zones and wet zones of equatorial forests, they constantly experience the influence of both. Moisture does not last long enough in the savannas to grow multi-tiered forests there. Also, dry winter periods, which last 2-3 months, do not allow the savannah to turn into a desert.

Savannah zones are very large, that's why on theirnorthern and southern boundaries of vegetation is slightly different. The savannahs, which border on the desert zones in northern Africa, are very rich in drought-resistant small grasses, such as acacias and aloes with branched roots. Now you know what the savannah is!
