The Victorians were fascinated by the art of weather forecasting, and had a number of intriguing devices with which to make their own predictions. This operates on the same basic principle, using the three most important influences on weather conditions - barometric pressure and trend, plus wind dir..
This little pocket forecaster, only 2" in diameter, is remarkably reliable for predicting general weather conditions in and around the British Isles in conjunction with a pressure reading from a barometer, and was a favoured instrument 90 years ago. Based on established meteorological principles, it..
Inspired by originals in the Science Museum. The gnomon, which casts the shadow, can be set for latitude on a sliding scale; and the whole instrument oriented in the meridian by means of a magnetic compass in the base. A spirit level and height-adjustable legs ensure that the instrument is used upri..
Wooden-boxed brass sundial is a completely self-contained portable instrument, inspired by a design from the 18th century instrument maker Peter Dollond, founder of a great optical empire. The original is in the London Science Museum. Instruments like this were once used by explorers and navigators ..
This feature-packed little instrument fits easily into a pocket so you'll always have easy access to: Digital Compass, Altimeter, Barometer with weather forecasting function, Time, Date, and Alarm. Backlit LED screen...
Set into an elegant brass porthole are four instruments to give you an at-a-glance guide to the prevailing conditions - a barometer, with aneroid movement and scale in inches and millibars, a thermometer in C and F, a hygrometer, and a clock. Measures 31cm across. Clock requires 1xAA battery.Dimensi..
These forecasters operate on a Victorian principle that use barometric pressure and trend, plus wind direction and time of year to give a simple but remarkably accurate weather forecast for the UK – an invaluable aid to interpreting barometer readings. The brass dials are acid etched and picked out ..
Aboard HMS Beagle during the Darwin Expeditions of 1831-36, Captain Robert Fitzroy developed and refined the 18th century storm bottle. This involved much testing and observation of crystal formations, and resulted in him being able to make a number of weather predictions with a fair(ish) degree of ..
