Forecasters use a special tool called a barometer. It measures air pressure. Barometers measure atmospheric pressure using mercury, water, or air. You’ll usually hear forecasters give measurements in either inches of mercury or in millibars (mb). Changes in air pressure, as measured with barometers, predicts short-term changes in the weather.As temperature increases, pressure decreases. Conversely, as temperature decreases, pressure increases. As air warms, it rises in the atmosphere, resulting in lower barometric pressure. Cool air, on the other hand, sinks towards the Earth's surface, increasing the air pressure in that area. In general, areas of low pressure have a higher chance ...
