4.2 Weather forecasting
Sunny Partly Cloudy Cloudy Rainy
The four weather icons Sunny, partly Cloudy, Cloudy and Rainy represent the weather
forecasting. There are also two weather tendency indicators to show the air pressure
tendency between the weather icons.
The weather forecasting is based upon the change of air pressure.
4.3 Weather tendency indicator
The weather tendency indicators arrow is located between the weather icons to show
the air pressure tendency and provide a forecast of the weather to be expected by the
decreasing or increasing air pressure. The rightward arrow means that the air
pressure is increasing and the weather is expected to become better. The leftward
arrow means that the air pressure is decreasing and the weather is expected to
become worse.
The change of weather forecast icon is in accord to the relationship between current
relative pressure and the pressure change since last six hours. If the weather is
changing, weather tendency indicator (animated arrows) will be flashing for three
hours indicating a weather change is happening. After that, if weather conditions have
become stable and no new weather change condition met,then the arrows will be
fixed.
