As regards the first, I will commence with a few brief remarks on the effects of varying barometric pressures.
By this means some notion might be formed of the general direction of the line of barometric pressure preceding or succeeding a storm.
If a line were drawn through all points on the surface of the earth having an equal barometric pressure at the same time, such a line would be called an isobar.
Sealed against the vacuum of space, barometric pressure outside made no difference.
Thirteen cubic feet of free air at normal temperature and barometric pressure weigh about one pound.
These vessels recorded temperature, barometric pressure, currents, ice conditions, exact latitudes and longitudes and sent these observations to the institute.
However, barometric pressure is strongly correlated with many other meteorological factors that require more thorough investigation.
Approaching storms from the southeast or eastsoutheast are usually indicated by the occurrence of slight variable winds and a rapid fall in barometric pressure.
