THE WEATHER TENDENCY INDICATOR
Working together with the weather icons are the weat her tendency indicators (the upward and downward
arrow located near the Weather man). When the indicator points upwards, it means that the air-pressure is
increasing and the weather is expected to improve, but when indicator points downwards, the air-pressure
is dropping and the weather is expected to become worse.
Therefore, user may see how the weather has changed and is expected to change. For example, if the
indicator is pointing downwards together with cloudy icons, it means that the last noticeable change in the
weather was when it was sunny (the sunny icon only). Therefore, the next change in the weather will be
the cloudy icons since the indicator is pointing downwards.
