g) Weather Forecast Function
The weather forecast of the weather station is one of the most interesting fea-
tures. Although the weather station, of course, can’t replace the professional weather
forecast by highly qualified meteorologists on the radio, television or Internet, it is
amazing that only based on the measurement and observation of the barometric
pressure of the past days, an accuracy of about 70-75% can be reached.
In the following, you will find additional explanation regarding the icons and
their meaning:

In the following, you will find additional explanation regarding the icons and

—
If ”Sunny” is displayed at night, this means a starlit night.
—
For outdoor temperatures below -3 °C (26 °F), precipitation is displayed as snow

The display does not represent the momentary weather situation, but is a

forecast for the next 12 to 24 hours.
—
The calculation of the weather forecast only based on the barometric pressure
only results in a maximum accuracy of about 70-75% for the next 24 hours.
Therefore, the weather may be completely different on the next day.
As the measured air pressure is only valid for a region with a diameter of approx.
50 km, the weather may change quickly. This is especially true in hilly or
mountainous locations.
Therefore, don’t depend on the weather forecast of the weather station, but
inform yourself locally when you would like to hike in the mountains, for example.

In case of sudden or larger air pressure fluctuations, the display symbols are
updated to indicate the weather change. If the display symbols do not change,
either the air pressure did not change or the change occurred so gradually that
it cannot be registered by the weather station.

The display symbols indicate a weather change for the better or worse, which
does not have to mean sun or rain, however (as indicated by the symbols).
For example, if the current weather is cloudy and rain is displayed, this does not
mean that the device malfunctions, but rather that the air pressure has dropped
and that a worse weather condition is to be expected, which does not necessarily
have to mean rain, however.

After commissioning, you should not pay attention to the weather forecasts for
the first 12 to 24 hours, because the weather station first has to collect air
pressure data in this period at a constant height above sea level to make a more
exact forecast.

If you take the weather station to a place that is significantly lower or higher
than the original site (e.g. from the ground floor to the top stories of a building),
the weather station may interpret this as a weather change.
