How Do Weather Stations Work?

How Do Weather Stations Work?
2
Features

• There are a series of tools included on most
  weather stations. Most of them include a
  thermometer to pick up the current temperature, a
  barometer to gauge air pressure, a hygrometer for
  humidity, and a rainfall gauge to determine how
  much rain has fallen during a given period. Some
  more complicated devices also have things like
  optical sensors for measuring cloud cover and
  sensors to measure things like soil moisture
  levels.

Considerations

• If you're looking into purchasing a home weather
  station, there are a few things you will need to
  consider. Ease of set-up and wireless
  transmission range are going to be important
  factors--if you can't set it up, and you can't
  get the information from your home, it will be
  harder to use.

Function

• By measuring the variables taken by the weather
  station, you can get a picture of what's going on
  in the world around you, weather-wise. A snapshot
  of these data points doesn't give you a lot, but
  if you track those variables over time, you'll
  have something a little more useful. Looking at
  the patterns that are going on currently, as
  compared to patterns in past weather situations
  gives weather men a vague idea of what should
  happen in future.

5
Misconceptions

• Accurate predictions of the weather are actually
  virtually impossible. A prediction made using
  data from weather stations is predominantly a
  guess. It's a guess based on previous patterns in
  the weather.
