Barometer. A barometer for measuring atmospheric pressure and hence predict the weather. The pointers at left indicate the atmospheric pressure and the predicted weather on the barometer face. The image is coloured red around the 'very dry' reading. This could signify global warming. This is an aneroid barometer in which changes in atmospheric pressure causes a vacuum chamber to expand or contract. This deformation causes a pointer to move around the face of the barometer to reveal the atmospheric pressure. High pressure generally indicates a period of dry weather,whilst low pressure weather systems tend to be rainy | |
