WEATHER FORECAST
The built-in barometer can notice atmosphere pressure changes 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
