Ship's Hull Tendency Barometer

shipshull.jpg

You can forecast weather just like 17th Century mariners did with this wall mounted Ship's Hull Tendency Barometer. Glass tubes are positioned above a model sailing ship's wooden hull. We understand that barometers measure atmospheric pressure, but what exactly is a tendency barometericon?

The tendency barometer was patented on December 23, 1818 by Alexander Adie, a Scottish optician, calling it a Sympiesometer. Sir James Clark Ross used it on his expeditions. The tendency barometer consists of two liquid filled tubes mounted parallel to each other. The barometer tube is in a U-shape, which is open-ended and filled with a red fluid, and a closed thermometer tube is filled with a blue fluid. You can predict the weather with glance across the room:

  • When the fluid levels are equal, the weather is changing.
  • When the red fluid level is below the blue fluid level, the weather is fair since high pressure pushes the red fluid down in the tube.
  • When the red fluid level is above the blue, stormy weather is predicted as low pressure allows the red fluid to rise in the tube.

The Ship's Hull Tendency Barometer would make a tremendous Father's Day gift. It comes fully assembled on a frosted-glass frame and sturdy hanging hardware is included.

How to Forecast the Weather Without Electronic Gadgets

right_60_percent_of_the_time.jpg

While we love our electronic weather gadgets, it's important to learn to predict the weather on our own too. Nature actually tells us a lot of what we need to know if we pay attention and can read the signs.

We found a quick primer on the basics over at the Art of Manliness, Forecast the Weather Like Daniel Boone covering Cloud Signs, Proverbs That Stand the Test of Time and Tools of the Trade: The Barometer, which should interest you if you are a budding or seasoned weather buff.

While we can observe cloud signs and memorize the weather proverbs as the above article recommends, in order to predict accurately we really need to measure atmospheric pressure. So yes, a barometer is a gadget, but not an electronic one. Once we have our barometer, we then need to be able to interpret it. The aforementioned article provides a barometer reference card (below), taken from Skills for Taming the Wilds by Bradford Angier.

Chaney Instrument Galileo Thermometer with Glass Globe Barometer

galileoglobe.jpg

Place one of these eye-catching Galileo units on your desk or bookshelf. It will surely be noticed. This Galileo Thermometer with Glass Globe Barometer from Chaney Instrument blends old and new technology to provide your desktop weather report. The entire unit is mounted on a wood base.

How does it work? A Galileo thermometer is filled with a clear liquid that suspends multiple colored weighted glass bubbles. As the liquid within the bubbles changes temperature, their density also changes, allowing the weights to rise or fall and thus creating a gauge.

The glass water barometer responds to changes in the air temperature. Fair weather is indicated by a low fluid level in the glass spout while a higher fluid level in the glass spout means inclement weather is in your future. This decorative barometer features a lovely etching of our Earth's continents.

How a barometer measures air pressure

barom2.jpg

We found this article at USA Today very informative on how a barometer works.

Air pressure and differences in pressure are among the most important weather makers.

The centers of storms are areas of relatively low air pressure, compared to pressures around the storm. High air pressure generally brings good weather. Keeping track of how the pressure is changing is important for forecasting the weather.

Differences in air pressure between places cause the winds to blow - air moves from high toward low pressure.

The instruments that measure air pressure are called barometers, from Greek words for weight and measure.
