BAROMETER

Barometer function, indication of the meteorological trend

Description of the function

In this mode, your watch is transformed into a BAROMETER. The hands superpose to indicate the meteorological trend.

Explanations

Changes in weather are linked to variations in atmospheric pressure.

The watch measures these variations in pressure and indicates the meteorological trend.

When atmospheric pressure increases, the sky clears. The hands move to the right.

This is called a "high pressure" zone or "anticyclone" (A).

When atmospheric pressure decreases, the sky clouds over. The hands move to the left.

The is called a "low pressure" zone or "depression" (D).

The change in pressure is measured and displayed using the hands which can assume the following 7 positions depending on the meteorological trend:

-6' : Major drop in pressure, rapid deterioration

-4' : Moderate drop in pressure, probable deterioration

-2' : Minor drop in pressure, probable slight deterioration

12h : No notable meteorological change

+2' : Minor increase in pressure, probable slight improvement

+4' : Moderate increase in pressure, probable improvement

+6' : Major increase in pressure, rapid improvement

Miscellaneous information

The program on your watch takes into consideration variations in atmospheric pressure over the previous 8 hours to calculate the trend to be displayed, ensuring greater reliability and precision than a "mechanical" barometer which only displays an instantaneous trend.

Furthermore, the variation in pressure caused by a rapid change in altitude is detected by the program and compensated for automatically. It therefore has no influence on the barometric trend.

Unit conversion: 1 hectoPascal [hPa] = 1 millibar [mb]
