Low pressure
Why study barometric pressure?
Generally, bad weather is associated with low barometric pressure and fine
weather with high pressure. A low pressure area is surrounded by air of
higher pressure. As the higher pressure air cannot move in the low pressure
area, it will move upwards, causing condensation of water in the air and
producing clouds. The opposite is true for high pressure: in a high pressure
area, air of lower pressure will move downwards, warming up the air and
evaporating the water in the air.
Pressure trend
The trend pointer displayed at [A2] indicates the trend of the barometric pressure.
Indicates that the barometric pressure trend is increasing.
Indicates that the barometric pressure trend is steady.
Indicates the barometric pressure trend is decreasing.
The bar graph lets you see the pressure trend over a period of 12 hours. The bar graph will show the
pressure trend by default. To view the indoor temperature trend or the outdoor temperature trend, press
Snooze [5]
in Clock1 mode.
The sequence is:

Inside Temperature Trend
Outside Temperature Trend
Note:
The weather forecast, by the means of the animated icons, depends on the evolution of the barometric
pressure. By consulting the barometric pressure historical graph you can evaluate the likeliness or the
strength of the weather forecast currently displayed. For example, if the pressure has steadily increased
over the past 12 hours but decreases slightly in the next 3 hours, the weather station might forecast rain,
but you could expect the probability of rain to remain low. On the other hand, if you observe a sudden
and large shift in pressure, the weather forecast is more likely to be extreme. For example, if the
forecast is rain, and you observe a large and sudden downward shift of pressure, the rain is likely to be
heavy.
The comfort level will be established based on the data collected from indoor temperature/humidity. The
indicator below will display whether the level is comfortable, normal or uncomfortable.
Comfort Level Description
It shows that the current environment is within
the ideal range for indoor temperature and
relative humidity.
It shows that the current environment is
acceptable.
It shows that the current environment is containing
inadequate moisture, too cold or too hot.
