I'm from New York, USA, so I'm wondering how dry and wet seasons work. I think it has something to do with high and low pressure and clouds and all, but I was wondering if anybody could tell me what happens, say in Cuzco, Peru that causes them to have wet and dry seasons. Thanks!

It odes have to do high and low pressure In many tropical regions, there is a an area called the Inter Tropical Convergence Zone (ITCZ) which is an area of low pressure where the sun is directly (or almost directly) overhead, to the north and south are areas of high pressure called the doldrums. The ITCZ, being low pressure causes air to rise and create clouds and heavy rains. The Doldrums being areas of high pressure causes air to sink and this discourages cloud formation and precipitation. In areas with both wet and dry seasons, for part of the year they have the ITCZ and the other part of the year they have the doldrums influencing the climate.
