Some people don’t know what weather elements on a weather station means and how to read it. So here is our guide on how to read the weather element on a weather station and what it means.
What is the role of a weather station?
The weather station measures wind speed and direction or record rainfall. Those data go into a small electronic data logger, which then uploads to a web site or app.
Processing involves integrating those inputs to generate weather maps or look up local conditions on a specific weather-related variable. In the context of climate change, the output of meteorologists on the website is generally viewed with a cautionary eye because checking the weather stations is working properly
What are the Different Weather Elements?
What is temperature?
A thermometer measures the air temperature with a probe sticking out of the ground. The high and low temperatures are recorded, and the middle of the air temperature is the measured temperature.
Atmospheric pressure, known as barometric pressure, is the force exerted by the weight of the air and is typically expressed as a reference level of atmospheric pressure. At sea level, atmospheric pressure is maintained at 14.7. pounds per square inch (PSI).
If a weather station has an outdoor reading, the pressure must be measured outdoors at a specific atmospheric pressure. The lowest atmospheric pressure reading can be taken outdoors is 13.7 psi, and the highest is 28.7. PSI.
In all cases, it is illegal to take a measurement when atmospheric conditions might be affected by, or could result in, significant weather. Most weather stations measure air temperature as it changes with the seasons.
Humidity is a measure of the water content in the air. A measure of relative humidity is the dew point. A water content measurement that falls within the range between 60% and 100% indicates relative humidity.
When the dew point is above 60%, there is a higher water content in the air than at its dew point (the air is saturated). When the dew point is below 60%, the air is not saturated.
The pressure in a column of air is measured by placing an air gun up to the sensor, which usually has a ducted flue for a cold air return, and releasing compressed air through a funnel onto the sensor.
This measurement is then used to determine air density.
Like many other meteorological parameters, the degree of precipitation in an area determines how the weather station is categorized. Precipitation measurement is made by adding water in a vial to a thermometer in a cloud seeding chamber.
An analog meter is used for water temperature and relative humidity when placing the water into the room. The readings for precipitation are taken while it is in a dry location. The readings will vary throughout the day, depending on changes in temperature, wind speed and direction, humidity, and cloud cover.
During the day, other readings are made of temperature, air pressure, and atmospheric pressure. Temperatures, air pressure, humidity, and air movement are recorded in a control box.
Wind speed and direction:
For long periods, the station is not close to the wind direction or the average wind speed, and so there is usually a lag time of a few minutes before weather observations can be made.
If the weather station is located on an open plain with clear skies, then clear weather should be recorded by instruments, and if it is on a hilltop or in a cloud, then cloud cover should be measured.
Visibility increases with wind speed and the type of clouds. The wind speed is measured at 20 meters (65 feet) above the surface by a meter for the airport and Metherex at 3 meters (10 feet) above the surface by a meteorological station.
The Methanex is in direct line of sight to the airport and is connected to the other stations by an antenna. Meteorological readings are taken on an automatic scale, so the reading is not recorded if the meter needle gets stuck.
Suppose the meteorological station is not 100 percent accurate, for example, because there is too much smog in the atmosphere or it has not been reset correctly. In that case, the reading may not be accurate.
Clouds result from clear, sunny, or overcast weather and represent the absence of sunlight in the sky. Cloud covers are a reflection of temperature and moisture on the Earth’s surface.
A cloud’s height is determined by the difference in temperature between its surface and the air temperature between its character and its top. This means the more significant the temperature difference, the higher the cloud will be.
Cloud covering height is affected by temperature, humidity, precipitation, wind speed and direction, and visibility.
