WEATHER FORECAST
The built-in barometer continually monitor atmosphere pressure. Based on the data
collected, it can predict the weather conditions in the forthcoming 12~24 hours within a
30~50km (19~31 miles) radius.
Sunny
Partly cloudy
Cloudy
Rainy
Rainy / Stormy
Snowy
NOTE:
- The accuracy of a general pressure-based weather forecast is about 70% to 75%.
- The weather forecast is reflecting the weather situation for next 12~24 hours, it may not
necessarily reflect the current situation.
- The SNOWY weather forecast is not based on the atmospheric pressure, but based on
the temperature of outdoor. When the temperature is below -3°C (26°F), the SNOWY
weather icon will be displayed on the LCD.
BAROMETRIC PRESSURE
The atmospheric pressure is the pressure at any location
of the earth caused by the weight of the column of air
above it. One atmospheric pressure refers to the average
pressure and gradually decreases as altitude increases.
Meteorologists use barometers to measure atmospheric
pressure. Since variation in atmospheric pressure greatly
affected by weather, it is possible to forecast the weather by
measuring the changes in pressure.
