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 .
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 .
