Abstract

Winds of climate change Simple theories suggest that global warming will weaken atmospheric circulation in the tropics during the twenty-first century. Now a reconstruction of atmospheric circulation in the tropical Pacific since the mid-nineteenth century suggests that it has indeed reduced in strength in the past, consistent with both theory and model simulations. Perturbation experiments indicate that this effect can be attributed to human influences. Tropical Pacific atmospheric circulation is a major influence on large-scale oceanic circulation, and the modelling suggests that weakened surface winds may have altered the thermal structure and circulation of the tropical Pacific Ocean.
