Detection of human influence on sea-level pressure
- Detects an influence of anthropogenic greenhouse gases and sulphate aerosols in observations of winter sea-level pressure (December to February), using combined simulations from four climate models
- Finds increases in sea-level pressure over the subtropical North Atlantic Ocean, southern Europe and North Africa, and decreases in the polar regions and the North Pacific Ocean, in response to human influence
Note
Changes in air pressure could have a big effect on climate. Air pressure controls the atmosphere's circulation, and therefore influences how moisture moves. Changes in circulation can alter rainfall, temperature, winds and storminess.
