Garden Rain Gauge And Other Weather Instruments
Being aware of existing weather conditions and predicting future weather patterns may seem like work reserved for a meteorologist, but that just isn't so. The normal person can gather equipment that can do those things and more. Some of the basic weather instruments required to accurately record the conditions include a garden rain gauge, an anemometer (also called a wind gauge), a thermometer, a barometer and a weather vane.
A standard eight inch garden rain gauge consists of a receiving funnel, a measuring tube and a measuring stick. It is generally supported on a wood or metal post or stand. The measuring stick is usually marked in either inches or millimeters. To obtain a precise rainfall measurement, you just position the measuring stick inside the measuring tube and read the amount on the stick. Electronic models remotely itemize rainfall data in daily, weekly and monthly rainfall totals, averages and rates per hour. You can also get a garden rain gauge that is self-emptying. This allows you to record rainfall amounts over much longer periods of time.
A device used to determine the momentum of the wind is known as an anemometer, or wind gauge. In its most simple form, it is a cup anemometer, which consists of four hemispherical shafts mounted horizontally on a vertical shaft. Wind gauges are generally divided into two broad groups: hand-held and fixed. A hand-held anemometer will as a rule merely display the present wind strength. A fixed wind gauge calculates the wind speed at a particular site in addition to providing historical measurements, such as maximum gust and average wind speed.
A thermometer is, of course, used to calculate the temperature. Thermometers have become much more advanced since the time of a simple mercury thermometer. Now wireless is enormously popular, because from the comfort of your favorite recliner, you can check the present, minimum or maximum temperatures and have it displayed in Celsius or Fahrenheit. You can also get a garden rain gauge thermometer that takes temperature readings as well as a rainfall measurement.
A barometer measures the atmospheric pressure and can be used to see if the pressure is rising or falling or is steady; thus providing a good indicator of the weather in the near future. However, barometers are a lot more than just a weather instrument. They can even be a work of art. Ornamental barometers add beauty and style to the walls of a lot of homes. Technology has caught up with barometers, so digital barometers are now commonly available and just as in the aforementioned instruments, can be used to measure atmospheric changes; aiding in a more precise picture of the upcoming weather.
Quite simply, a weather vane's job is to measure and gauge the wind direction, which is an essential component to any weather forecast. As with a barometer, when ornamental, they can also be a charming addition to your backyard or gazebo roof top. There are an almost unlimited choice of designs and styles to choose from; the more popular styles include sports, birds, animals and others. There are craftsmen out there who can provide you with your very own hand-crafted, specialty weather vane.
Weather stations typically bundle many, if not all of these instruments together so that you can get a better overall picture of current weather conditions, as well as to predict future conditions. A wind gauge, garden rain gauge, weather vane, anemometer and barometer can each provide you with a preview of what is going on right outside your door. Many times several of these instruments are sold together in a weather station for added convenience and quick reference. It doesn't matter why the weather interests you, it is a captivating and ever-changing pastime.
