Station pressure and sea-level pressure can never be the same value.

The base value of an isobar is ____.

On an isobaric surface, ____.

If you (in the Northern Hemisphere)stand with the wind aloft to your back, Buys Ballot's law states that lower pressure will be to your right and higher pressure to your left.

At sea level, standard atmospheric pressure is ____.

Winds blow slightly inward ____.

The unit of pressure designated by the International System (SI)of measurement is the ____.

A ____________________ barometer uses a transducer to detect the change in pressure exerted by the atmosphere on a precisely engineered surface, and the change in pressure is then converted into an electrical signal.

The unit of pressure most commonly found on a surface weather map is ____.

How does an aneroid barometer differ from a mercury barometer?
