TOPIC-2 Subtropical Anticyclones (high pressure cells) are known for dominant cold dry sinking
air. With reference to the Kalahari High Cell, conduct a research in which you outline
the impact of the prolonged stay of the anticyclone in winter months in the central
plateau. Your research should highlight impacts on economy, environment and food
security

High pressure cells in the region occur in winters and replace the warm thoughts creating dry and cold weather.

Explanation:

An anticyclone is opposite to a cyclone and it refers to the weather phenomenon. Defined in terms of the large scale of the winds. It moves clockwise in the north and anticlockwise south.  The anticyclone forms over the Kalahari high during the winters in the interior parts of southern Africa and forms a part of subtropical ridges. Due to which the Kalahari is a desert region.  When the eat is heated near the poles the equatorial motion force h ends upwards and as the air rises slowly it cools and subsidies near 30-degree latitude are called as Hadley cell. Most of the economic activity of this region such as cattle rearing is affected due to the slow growth and small vegetation. The food and health of the Bantu people are impacted by dry and cold conditions.

Geothermic gradient is the rate of increasing temperature with respect to increasing the depth in the earths interior. away from tech tonic plates boundaries, it is about 25-40 c/km (72-87 degrees f/mi) of depth near the surface in most of the world.

Answer (d) may increase or decrease porosity through dissolution or deposition;
