Q.

When the barometer reading dips suddenly, it is an indication of –

A. Hot weather
B. Calm weather
C. Storm
D. Dry weather
Answer» C. Storm
Explanation: Sudden and great fluctuations of the barometer at any time of the year indicate unsettled weather for several days, perhaps a fortnight. If the barometer falls two or threetenths of an inch in four hours, one can expect a gale of wind. If the surface of the mercury in the cistern of the barometer vibrates upon the approach of a storm, the gale can be expected to be severe.
