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.
4.4 Examples of changing weather icons:
4.5 Storm warning indicator
The storm threshold can be set
to suit the user’s requirement for storm forecasting from 3-9hPa (default
4hPa). When there is a fall over pressure threshold within 3 hours, the storm forecasting will be activated,
the clouds with rain icon and tendency arrows will flash for 3 hours indicating the storm warning feature has
been activated.
Notes to pressure sensitivity setting for weather forecasting:
The pressure threshold can be set to sui
t the user’s requirement for weather forecasting from 2-4hPa
(default 2hPa). For areas that experience frequent changes in air pressure requires a higher setting
compared to an area where the air pressure is stagnant. For example, if 4hPa is selected, then there must
be a fall or rise in air pressure of at least 4hPa before the weather station will register this as a change in
weather.
