A barometer is an instrument for measuring air pressure, first invented by Evangelista Toricelli, a pupil of Galileo, in 1643. There are two main types of barometer: a mercury barometer, in which the pressure of the air forces a small column of mercury up a tube (similar to a mercury thermometer); and the anaerobic barometer, in which one or more aneroid capsules (aneroid means ‘without air’) expand/contract with changing air pressure. More (opens rest of text)

The barometer and altimeter (air pressure changes with both altitude and weather conditions) measure air pressure with two small aneroid capsules stacked one above the other – the top one being clearly visible on the dial side at 5 o’clock.

The aneroid capsules in the Génie 01 were especially developed to Breva's specifications to optimise their precision and use in a wristwatch. The capsules are made from a special non-magnetic memory-metal (Breva patented invention), which is lighter and stronger than aluminium and has twice the ductility of steel. The capsules are exposed for long durations to high temperature and pure oxygen to maximise thermal conductivity and oxidation resistance.

A clearly visible lever rests on top of the aneroid capsules and transmits the combined height of the capsules through a complex system of gears and racks to the altimeter indication and the barometer. The gearing for these two displays has been carefully calculated as the scale of changing air pressure due to altitude variations is quite different to weather variations.

The Breva Génie 01 has Altitude! The altitude scale on the Génie 01 arcs across the top of the dial and measures 0-5,300 metres. Before using or adjusting the 5,300m/17,000' altimeter, air pressure inside the movement should be equalised with the exterior air pressure valve at 4 o’clock (bottom right of image).

As the altitude indicator hand is directly linked to the air pressure, the pusher at 2 o’clock moves the altitude dial (rather than the hand) left or right to fine tune the display.

Extreme Weather: Supercell thunderstormsWhile this storm cloud may look like an alien spaceship, it is actually a massive thunderstorm called a supercell. A supercell  is a thunderstorm characterized by the presence of a mesocyclone, which is a deep, persistently rotating updraft. Because of this, supercells are sometimes referred to as rotating thunderstorms.

This one was photographed in Montana, USA by Sean Heavey and featured on Nasa's excellent Astronomy Picture of the Day. For more of Sean's photography please visit http://www.seanrheavey.com/
