Weather Forecast - Conrad W224-7 Mode D'emploi

o) Weather Forecast
The weather forecast is one of the most interesting features of the weather station.
Although the weather station cannot replace professional weather forecasting by highly
qualified meteorologists on the radio, TV or internet, it is amazing that just measurement and
observation of the last days' barometric pressure permits forecasts at an accuracy of 70%.

Right after commissioning of the weather station (if the weather station was
connected via the plug-in mains adapter), the weather forecast symbols flash.
Set the weather situation as described in chapter 9. c). This enables faster and more
precise display of the weather forecast.
if the weather situation is to be set subsequently, observe chapter 11. b).
We would like to offer some more information on the symbols and their meaning:
• If "sunny" is displayed at night, it means a starry night.
• The display does not indicate the current weather situation, but a forecast for the next 12 to
24 hours.
• Calculation of weather forecasts only based on barometric pressure leads to a maximum
accuracy of about 70%. The actual weather at the next day may be completely different.
Since the barometric pressure measured only applies for an area with a diameter of approx.
50 km, the weather may also change quickly. This particularly applies in mountain or high
mountain areas.
Therefore, do not rely on the weather station's forecast but gather information on site, e.g.
for mountain tours.
• At sudden or larger fluctuations of barometric pressure, the display symbols are updated to
show weather changes. If the display symbols do not change, either the barometric pressure
did not change or the change is so slow that it could not be registered by the weather station.
• If the forecast "sunny" or "precipitation" appears, the display does not change even if the
weather improves (display "sunny") or deteriorates (display "precipitation"), since the
displayed symbols already represent the two extremes.
• The symbols show improvement or deterioration of the weather, but this does not necessar-
ily mean sun or rain (as indicated by the symbols).
If the current weather is cloudy and rain is indicated, this does not mean that the device is
malfunctioning, but it indicates that the barometric pressure dropped and weather is
expected to deteriorate. It is not necessarily going to rain.
