How is the data collected?
Meteorologists use different types of equipment in order to record the data that will be the base for their forecasts. Thermometers, radar systems, barometers, rain gauges, wind vanes, anemometers, transmissometers, and hygrometers are some of the pieces of equipment used for this purpose and they all provide bits and pieces that put together result in what we know as weather predictions.
- Thermometers are the equipment that is probably the most common. The liquid inside them expands and shrinks depending on the environmental temperature, and this is how the outdoor temperature is predicted.
- Barometers are pieces of equipment that measure the pressure in the atmosphere. The pressure in the atmosphere increases with the altitude. For example, the higher on a mountain you climb, less air will be found.
- Rain gauges are simple pieces of equipment that measure the precipitation quantity that is registered in a container.
- Hygrometers measure the humidity that is registered in the air on a given location.
There are many other pieces of equipment that can be used for predicting the weather, and from them we can name weather balloons, satellites and weather stations. They all contribute to how accurate the data collected is, and therefore, how accurate the weather forecasts will be.
