What do weather instruments do?
Up in the air?
Can you believe that there is a balloon that measures weather? Meteroligists use a tool called a weather balloon to see what the weather might be in the future. It measures temperature, wind speed and air pressure just by going up in the air. At the bottom of the weather balloon there is a measurer that calculates the weather and transports the conditions back to a computer in a weather station.
Beaufort scales measure wind speed and wind force by using numbers and symbols. It is a chart that tells you what happens when different types of wind accure. For example, a severe storm's beaufort number would be 11 because it does serious damage to houses. The wind speed would show 110 km/h.
Barometers are used to measure air pressure. If a barometer is low it means bad weather. If a barometer is high it means good weather.
Rain Gauges and snowsticks
A rain gauge measures rain. It is basically a compartment stored outside that collects rain and measures it. Snowsticks are quite similar. When snow falls from the sky this tool collects it and measures it.
Satellites calculate weather from space. They have a lot of sensors that help it measure weather. If the satellites look at earth they can see many clues to when a storm is coming. If a swirl is seen, then a hurricane might be accuring in that part of earth. The pictures shown below show hurricanes happening on earth.
