meteorograph

[‚med·ē′ȯr·ə‚graf] (engineering) An instrument that measures and records meteorological data such as air pressure, temperature, and humidity.

Meteorograph

an instrument for simultaneous recording of the temperature, pressure, and humidity of the air and, in some cases, of the rate of flow; it combines the functions of a temperature recorder, a recording barometer, a recording hygrometer, and, if necessary, an anemograph. Their readings are recorded by pens on a common chart, which is attached to a drum that has a clock mechanism; thus, a synchronized record of changes in temperature, pressure, and humidity over a period of time is produced on the chart. If a meteorograph is lifted into the free atmosphere, the altitude at various times during the ascent may be determined and the numerical values of the meteorological components at the altitudes may be established from the record on the chart by means of the barometric formula.

A distinction is made among probe meteorographs, which are lifted into the atmosphere by balloons; kite meteorographs, which are lifted by aerological kites; and aerostat and aircraft meteorographs. The aerostat and aircraft types are most frequently used. Aircraft meteorographs are mounted on a special support under the wing of a slow-speed airplane. The velocity of the airflow in the instrument compartment is recorded so that corrections for the friction of the airflow may be introduced into the temperature and humidity readings. During atmospheric sounding with high-speed aircraft, electrometeorographs are used. The type of meteorograph that transmits its readings by means of radio signals is called a radiometeorograph.
