weather [3] [comprehension quiz]

A weather vane is made up of a tail and an arrow. The tail fin catches the wind and the arrow points toward the direction the wind is blowing FROM. A barometer measures the weight of the air pressing down on you. The air pressure reading is measured in units called millibars. An anemometer measures wind speed. The stronger the wind blows, the faster it rotates. It counts the number of rotations, which is used to calculate the wind speed. Weather balloons measure temperature, humidity, and air pressure as they rise through the atmosphere. They also track wind speed and direction and this data is used to predict the weather. Thermometers help to measure the maximum temperature and minimum temperature on any one day in a particular place. The Met Office has a weather station network across the whole UK, with more than 200 automatic stations like this. The data is fed into a control centre in Exeter.
