Nautical barographs are used to keep ships and its crew safe from inclement weather. In the bygone times before satellites and computerized weather services were available, sea captains depended on these barographs. Barographs are recording barometers which automatically detect the weather variation on paper. These instruments record and display ups or downs and the rate of change in weather. A barometer always helped the sailor ‘foresee’ the kind of weather the ship has to face and take steps accordingly. For instance, if there is a rise in the atmospheric pressure, then it indicates clear and warmer weather. Similarly, if there is a fall in the atmospheric pressure, then it indicates cloudy skies and rainfall. They are also termed ‘weather observers’ as these instruments provide a graphic history of weather conditions.

A barograph is a recording aneroid barometer. It records barometric pressure over time on a paper or foil chart called barograms. A barograph has a metal cylinder which is connected with a pen arm. Pressure versus time is tracked down by the pen and is shown on the chart graphically. It records the proportional changes in the atmospheric pressure which further enables the meteorologists to study the obliging climate. Barographs still stay popular and are used to record altitudes and continuous flight duration for all badge and record claims.
Generally, a barograph is used both on the ground and in ships. Today, these barographs have been designed in various shapes and sizes, from small ones to the very large ones. You can also find these instruments in glass boxes. These glass boxes add a fancy look to the barograph. Commonly, these barographs gather the reading of the whole week. These instruments are also used in the flights are they measure the atmospheric changes with height. Barographs are not only considered wonderful instruments but they also make for lovely, practical and excellent decorative items.
