How to measure the Weather

How to measure the Weather


There are five basic instruments needed for an precise article of the weather. A rain gauge, anemometer (wind gauge), thermometer, barometer and weathervane.

1. Rain gauge. These come in all shapes and sizes from a basic glass jar with incremental measurements on the side, to a wireless rain gauge which can be located anywhere in your garden and remotely records data such as current rainfall total, current rainfall rate per hour and daily, weekly or monthly totals. They can also be self-emptying allowing you to portion large precipitation amounts over a period of time.

2. Anemometer (wind gauge). This is a gismo used to portion the speed of the wind. Its most basic form is a cup-anemometer consisting of four hemispherical shafts mounted horizontally to each other on a vertical shaft. Anemometers can be split into 2 broad groups, hand held and fixed. A fixed wind gauge can portion the wind speed at a given location, and also can supply historical measurements such as midpoint wind speed and maximum gust. A hand held anemometer meanwhile will ordinarily just display the current wind strength, however is very flexible as it can be carried anywhere so you can portion the wind speed at the coast or on the top of a mountain.

3. Thermometer. These devices of course portion the temperature. Thermometers have progressed a huge whole since the days of a easy mercury thermometer. Now wireless is all the rage, and from the comfort of your favourite armchair you can check the current, maximum or minimum temperatures and have it displayed in °C or °F. So if you are a keen gardener you will be able to judge how cold it is face and rule whether or not to cover your more sensitive plants.

4. Barometer. Now barometers portion the atmospheric pressure and again can be used to see if the pressure is rising or falling or steady, providing a good indication of the near future weather. however barometers are so much more than a weather instrument, they can be a work of art. Attractive barometers grace the walls of many a home, and I can remember as a child tapping our barometer every day to see if the pressure was changing and if the weather was going to be 'fine' or 'stormy'. Of course technology has caught up with air pressure too, so digital barometers are widely available and, as in the instruments above, can be used to portion atmospheric trends aiding in a more precise picture of the advent weather.

5. Weathervanes. Quite simply the weathervane measures which direction the wind is blowing from. A key component to any weather forecast. But, as with a barometer, they can also be an aesthetical increasing to your garden, or roof top! There is now an approximately unlimited range of designs ,the more beloved styles together with animals, birds, sports and many others. It is also potential to have your own hand crafted, designer weathervane.

All these weather recording instruments are widely available as personel units or bundled as a weather station. Anything your reasons for recording the weather, be it as a hobby or as a needful part of your profession, enjoy the weather Anything it throws at you!
