3.1.14 Weather threshold (2-4, default 3)
It’s pressure sensitivity setting for weather forecasting.
When the pressure rises
over weather
threshold
in past 12 hours the weather upgrades (like from partly cloudy to sunny). When the
pressure drops
over weather threshold
in past 12 hours the weather degrades (like from cloudy
to raining).
For areas that experience frequent changes in air pressure requires a higher level
setting compared to an area where the air pressure is stagnant. For example if 4 is selected, then
there must be a fall or rise in air pressure of at least 4hPa needed to change the weather forecast
icons.
3.1.15 Storm threshold (3-9, default 4)
Similar to the general pressure sensitivity setting it is possible to adjust the storm threshold
sensitivity form 3-9 (default 4). When there is a fall over storm threshold within 3 hours, the storm
icon will appear.
