Our weather is complicated. There are lots of things which when all put together describe the weather on any day. Weather Scientists, known as Meteorologists, have weather stations all over the world which are used to measure the weather in each location. The main things a weather station measures are given below:
- Wind speed How fast is the wind blowing? This is measured using an Anemometer or the Beaufort Scale.
- Wind direction From which direction is it blowing? A Wind Vane show the direction the wind is blowing in.
- Precipitation Is it raining or snowing and how much? Rain is measured using a Rain Gauge.
- Pressure Is there high air pressure or low pressure today? This is measured using a Barometer.
- Temperature How hot or cold is it today? This is measured using two thermometers. One to measure the maximum temperature one to measure the minimum temperature.
- Sunshine How many hours of sunshine have there been today? This was originally measured using a clever device called a Campbell Stokes Recorder. Nowadays there are electronic versions.
- Visibility Is it foggy, misty or clear?
- Cloud What types of cloud are about today or is it perfectly clear? To find out more about cloud types check out the BBC link in the weblinks section.
- Humidity This is how much moisture is in the air? This is measured using a Hygrometer.
