Forecasting sunny weather ahead with a chance of (alien) visitors
Four removable and interchangeable instrument Elements make up the Fifth Element:
Because weather forecasting is based on the speed of changes over time, the accurate time is required for meteorological observations. For the Fifth Element, L’Epée 1839 reengineered and skeletonised their 8-day clock movement to maximize transparency and visual access.
The barometer, which measures air pressure, is the mainstay of weather forecasting: as a general rule, increasing air pressure foretells good clear weather, decreasing air pressure portends inclement weather. The faster the change, the more extreme the coming weather.
The hygrometer measures the percentage of water vapour in the air; it displays this as a percentage of the maximum amount of moisture that might be held at a given temperature.
Thermometers don’t simply measure temperature, but the average kinetic energy of a substance: the higher the temperature, the higher the energy. A thermometer is essentially a power reserve indication of the energy in the atmosphere around us.
