In simple words, a weather station is a device that collects and records data about the atmospheric conditions prevalent wherever it is stationed. So if your question is, ‘ How does a weather station work ?’ Then, the simple answer for that is that these devices work using ordinary sensors to measure atmospheric conditions like temperature, rainfall, humidity, atmospheric pressure and even wind speed and direction.

To measure temperature, a weather station uses a different tool. So on and so forth; these different tools are the ones that are really equipped with the ‘sensors’ to measure the atmospheric conditions.

Given below are the basic tools that a weather station uses in order to record accurate data: Some expensive models will be having high quality sensors.

As an integral component of a weather station, it allows users to analyze changes in the atmospheric pressure. Changes in the atmospheric pressure impact the weather conditions and hence, a barometer is a very useful measurement tool.

It works by finding out the amount of pressure applied by the air on a particular surface area. Generally, a hygrometer is placed close to the thermometer as temperature has a great influence on determining humidity levels.

The most popular type of rain gauge is the one that works on the tipping bucket principle. Over time, weather has become more predictable as we are able to use various sensors to take readings around the world, from air pressure to the ambient temperature.

The electrical response (resistance) only has to change slightly to signify a one-degree adjustment in local temperature. The temperature sensor receives the readings and converts them to meaningful information that the weather station can use.

A few temperature sensors can be combined with a small solar panel to avoid the use of batteries. This type of sensor for a weather station typically uses force and pressure to accurately measure the atmosphere by seeing how it responds to it.

A voltage level is put out which later is converted over to a digital form for a weather station to use. The capacitor reacts with a modification of its capacitance and in changing provides data on humidity.

Additionally, a dew point which some sophisticated weather stations report involves using readings about temperature and humidity to create that statistic. A variety of different rain gauge designs are present with most weather station models.

The gauge also has protective meshes to ward off small insects or outdoor debris getting into the bucket and affecting the measurement. The equipment is positioned like erect points directed towards the sky in a collection with a good spacing between them.

The anemometer then uses data collected from all points to determine wind direction and speed which is passed on to the weather station. In so doing, the readings are collected on wind speed through the propeller and direct from the weather vane.

A voltage signal (analog) is created using the angle of azimuth which is later converted to digital. Propellers are four-blade designs that accurately confirm wind speed through the repeated blade rotation.

The voltage relates to the wind speed based on rotation and cup size to create an accurate representation. All these sensors work in combination to provide a comprehensive picture about current weather conditions and readings at a specific location.

The better home weather stations have more sensors and gauges to provide a complete picture of the current weather in the area. And accuracy through better product quality, sensible design and proper installation puts the finishing touches on a home weather station.

Drifting weather buoys outnumber their moored versions by a significant amount. Except for those instruments requiring direct exposure to the elements (anemometer, rain gauge), the instruments should be sheltered in a vented box, usually a Stevenson screen, to keep direct sunlight off the thermometer and wind off the hygrometer.

Personal weather stations have become more advanced and can include many sensors to measure weather conditions. These sensors can vary between models but most measure wind speed, wind direction, outdoor and indoor temperatures, outdoor and indoor humidity, barometric pressure, rainfall, and UV or solar radiation.

The quality, number of instruments, and placement of personal weather stations can vary widely, making the determination of which stations collect accurate, meaningful, and comparable data difficult. Personal weather stations typically involve a digital console that provides readouts of the data being collected.

The Citizen Weather Observer Program (Crop) is a service which facilitates the sharing of information from personal weather stations. This data is submitted through use of software, a personal computer, and internet connection (or amateur radio) and are utilized by groups such as the National Weather Service (News) when generating forecast models.

The Weather Underground Internet site is another popular destination for the submittal and sharing of data with others around the world. The UK Met Office's Weather Observations Website (WOW) also allows such data to be shared and displayed.

Home weather stations include hygrometers, pyrometers, thermometers, paragraphs, and barometers. Commonly wall mounted and made by manufacturers such as Air guide, Taylor, Springfield, Sputnik and Stormoguide.

It was also meant to aid in search and rescue operations and to support transatlantic flights. Since the 1960s this role has been largely superseded by satellites, long range aircraft and weather buoys.

Weather observations from ships continue from thousands of voluntary merchant vessels in routine commercial operation; the Old Weather crowdsourcing project transcribes naval logs from before the era of dedicated ships. With the decline of the weather ship, they have taken a more primary role in measuring conditions over the open seas since the 1970s.

During the 1980s and 1990s, a network of buoys in the central and eastern tropical Pacific Ocean helped study the El Niño-Southern Oscillation. The common instruments of measure are anemometer, wind vane, pressure sensor, thermometer, hygrometer, and rain gauge.

Some of these are basic to analyzing weather fronts and pressure systems, such as the synoptic observation network, while others are more regional in nature, known as mesons. Antarctic Automatic Weather Stations Project Australia: Bureau of Meteorology AWS network.

Actually, home weathers are not dissimilar from their much bigger brothers used for national and regional forecasts. A weather station is a meteorological device designed to measure different atmospheric conditions at a specific location.

It uses at least one or more sensors to measure and display atmospheric conditions (temperature, air pressure, humidity, wind speed, etc.) Based on build-in algorithms and calculations, most of these devices are also able to make short-term localized weather forecasts.

Technically, a simple analog thermometer placed against the wall inside your house to measure the temperature can be considered a home weather station. On the opposite end of the scale, you get a display console inside the home connected to an outside sensor array measuring up to 5 different atmospheric conditions.

An intricate set of algorithms and calculations build into the controller allows it to combine and interpret the various sensor readings. In turn, this enables the unit to make several “predictions” and determinations based on these calculations.

These forecasts home weather stations are able to make can be surprisingly accurate (if set up correctly). Advances in technology over recent years, combined with a continuing increase in/ understanding of weather conditions, is making this possible.

To be able to forecast the weather conditions accurately over several days, you literally need a much broader view. Combined with changes in water temperature monitored by ocean buoys (as well as additional data from remote weather stations and weather balloons), national and regional forecasts can be made for any large area over a number of days with astonishing accuracy.

In other words, big regional and national weather stations simply have a MUCH bigger reach than home weather systems, that allow them to make these extended forecasts. Living in an area that does not receive local weather reports (or very inconsistent ones) can be very frustrating for professionals working within roughly 15-25 miles from home.

Regional forecasts are too broad to give you a clear picture of your local weather. Spread out over a relatively large area, they rely on local weather conditions to plan anything from irrigation to the ideal time for planting seeds, to mention just a few.

This allows you to have more than one sensor array situated at different locations on your property to provide you with even more accurate readings. Large outdoor venues like stadiums and sports centers who need to know how weather conditions will change over a short period of time at their specific location will find such a weather station installed invaluable for short-term planning and event scheduling.

After this post, you should have a very clear idea of what a weather station is, how exactly it functions, and how it differs from bigger regional and national weather stations.
