To be able to give weather forecasts, meteorologists will normally make use of a blend of experimental simulations and measurements on sophisticated super computers. These are definitely not available to the ordinary man in the comfort of their homes looking to measure weather conditions for themselves. This is why the weather station becomes a very handy instrument. The station helps one to measure the current weather conditions using basic and simple instruments. They can be able to get accurate and reliable information without investing in very complicated resources or having to wait for the forecasts from the weathermen which are no always true. For one to be able to effectively use the weather station, they need to have a basic but clear understanding of the basic instruments that are used in this station. Below is information on some of these instruments.
- The thermometer
The thermometer is used in measuring temperature. Available in the market is a large variety of thermometers. However, the one that is most commonly used is the glass mercury one. It normally comes with a calibrated glass bulb containing liquid mercury. As temperatures rise, the mercury expands and rises within the glass bulb. One then uses the calibration on the glass bulb to tell the levels of temperatures. The temperature is usually read in degrees Fahrenheit or degrees Celsius.
Barometers are usually used to measure the atmospheric pressure. The type of barometer that is mostly used has a lot of resemblance to the mercury thermometer. It comes with a glass bulb containing mercury with the difference being that this particular glass bulb is open on one end and sealed on the other. The basic functioning of the barometer is that it balances the mercury’s weight against air pressure. The level of mercury will fall in the event that the mercury is heavier than the current air pressure and vice versa. The units that are most commonly used to measure the air pressure are bar and Pascal.
- The Anemometer
The anemometer is used in measuring the wind speed in the atmosphere. It comes with a plastic tube onto which is attached a free moving plate that is held onto a platform. The tube has a hole at the bottom that lets the wind exert force onto the plate causing it move within the tube. The tube has a scale on it that then allows for the reading of the wind speed. Normally wind speed is read in miles per hour or kilometers per hour.
- The Ombrometer
The ombrometers is used in the measurement of rainfall. They are usually very basic and very easy to use. They consist of a plastic container that has a millimeter scale printed on it. Wateris collected in the containerand then its level is read using the millimeter scale. There ishowever those that are more sophisticated and come with a digital scale that allows for the plotting of rainfall levels on computers.
The main role played by the weather stations is to allow eh ordinary man to tell weather conditions from the comfort of their home or office. This normally emails the reading of the basic weather elements individually including the wind, temperature, rainfall and atmospheric pressure. This is why these stations come with these basic instruments. For one to be able to fully utilize the power of the weather stations, it is thus important that they have a clear understanding of these basic instruments; what they are used for and how they are used. Lack of this knowledge will make it hard for one to get full benefits from the station.
It is not enough to just know how these instruments are used and what they are used for, it is also important that one understands how to take care of them so as to enhance their durability. Further reading on this subject matter becomes paramount. It is important to know the best places to position the instruments, how to store them and even how to clean them. For instance, it is no advisable to place the thermometer under direct sunlight as it will for one give inaccurate results and secondly it will be destroyed.
