15. Terminology

Sensed temperature
See „windchill".
Comfort indicator
The symbol of the comfort indicator (the three different „smiles"
climate whereby the weather station works according to the following table:
Temperature moisture
20%
<18°C
18-19,9°C
20-21,9°C
22-23,9°C
24-25,9°C
26-27,9°C
over 28°C
Independent of the ratio temperature to humidity, there are clearly delimited areas which are
defined as comfortable or uncomfortable climate.
For example, you feel humidity of under 30% to be too dry at a temperature of 25° C (e. g.
heating air) and humidity of over approx. 60% to be humid.
Dewpoint
This concerns a temperature which is dependent on the coincidence of a certain air pressure, a
certain temperature and a certain humidity.
The condensation of the humidity begins at this temperature point, the co-called thaw, the humidity
condenses and comes down as liquid (mist, vapour).
If the melting point for water vapour lies at below 0° C, condensation will take place as snow or
frost.
Weather forecast
The weather forecast of the weather station takes place by means of various weather symbols
which are calculated from the rising or falling speed of the air temperature (tendency).
This speed of change in the air temperature is the decisive volume for forecast of the approaching
weather, the absolute value plays a sub-ordinate role here. In general you can say that increasing
air pressure signalises better weather while falling air pressure, on the other hand, means poor
weather.
Windchill (equivalent temperature, sensed temperature)
The human being feels temperatures under certain circumstances quite differently from what a
thermometer can show. In the case of low outdoor temperatures, you sense the temperature on
the naked skin as being much lower the quicker any additional wind blows.
