In conjunction with the air pressure trend, further weather
interpretations are possible.
rising air pressure
constant air pressure
falling air pressure
Two examples:
Weather forecast shows rain, the air pressure is falling
off quickly and steeply >> strong rain is probable.
Weather forecast shows rain, the air pressure has risen
in the last 12 hours but in the last 3 hours as fallen off
somewhat >> light rain is probable.
