9. Explanation of terms
Perceived temperature - see Wind chill
Dew point - Temperature point that is dependent on the conjunction of a specific air pressure, a specific temperature and a specific humidity. At this temperature humidity begins to condense, the
Weather forecast - Forecast display using weather symbols, calculated from the speed at which the air pressure rises or falls (tendency).
The speed of change of air pressure is the critical factor for the prediction of the coming weather; the absolute value is of secondary importance. In general, it can be said that rising air pressure indicates better weather, while falling air pressure indicates deteriorating weather.
Wind chill equivalent temperature (perceived temperature) - A fictitious temperature, which the human body feels under certain conditions instead of the measured temperature, and which can be used at low temperatures (e.g. less than
