Answer 2

Explanation:

The pressure at a certain place depends on the density of air at that place. As the temperature increases, the density decreases and so does the pressure. Also density depends on the amount of moisture present in air. The following are a few indications of change in temperature with change in barometric pressure,

1) If the barometric height suddenly falls, it is an indication of a coming storm.

2) If the barometric height falls gradually, it indicates possibility of rain

3) If the barometric height increases gradually, it indicates the advent of dry weather.

4) If the barometric height suddenly increases, this indicates flow of air from that place to surrounding area which will mean coming of extremely dry weather.
