Abstract

The three-dimensional mesoscale circulation in the vicinity of the city of São Paulo is examined through model simulations validated by observational data obtained during a field experiment. The complex terrain surrounding the plateau where the city is located, plus proximity to the sea, represent the local controls on the wind field with implications for boundary-layer transport of atmospheric constitutents. The coupling of a regional-scale circulation with slope and sea-breeze circulations is an important feature which determines the wind regime in São Paulo in a summer situation not influenced by frontal systems.
