Asses the relative roles of subtropical anticyclones and the ITCZ in creating the characteristic features of the climate of tropical regions

Tropical regions are regions of the Earth surrounding the Equator. It starts and ends in the Tropic of Cancer in the northern hemisphere and the Tropic of Capricorn in the southern hemisphere. Many tropical areas have a dry and wet season. The wet season is the time of year, normally continuing for a few months, when most of the average annual rainfall will fall. But this is not the case for all tropical regions as tropical rainforest have rain throughout the year. Characteristic features of a tropical region include rainforests, dry deciduous forests, and arid deserts but could also be the other extreme, extending to alpine tundra and snow-capped peaks on mountains such as Mount Kilimanjaro. Tropical regions will produce a good crop yield late in the year if they have a fairly prolonged rainy season. Diseases such as malaria can be more common though as boggy marshland area are caused by the rainy season and harvest perfect breeding grounds for mosquitos.

The Intertropical Convergence Zone, or ITCZ, is the area encircling the earth near the equator where the north-east and south-east trade winds come together. This area is known by sailors as the doldrums. It is characteristically known for having no weather and in particular, no wind. It has no wind because the wind from the meeting trade winds is forced upwards. It is up in the atmosphere above the ITCZ where all the winds begin. In the Northern Hemisphere, the trade winds travel in a south-westerly direction from the north-east, whereas in the Southern Hemisphere, they move north-westerly from the south-east. When the ITCZ is situated north or south of the equator, these directions will change because of the Coriolis effect by the rotation of the earth. For example, when the ITCZ is placed north of the equator, the south-east trade wind changes to a south-west wind...
