baro-, bar-, bary- +

(Greek: weight, heavy; atmospheric pressure; a combining form meaning "pressure", as in barotaxis, or sometimes "weight", as in baromacrometer)

In an extended sense, these elements may mean "difficult" or "slow".

A graphic representation of changes in atmospheric pressure, as measured by a barograph (an instrument that continuously and automatically records changes in pressure on a rotating drum).
barograph (s) (noun), barographs (pl)
A barometer that is constructed so that it automatically describes the variations in atmospheric pressures: Since barographs produce descriptions of atmospheric pressures, they may be used to record elevation changes during aircraft flights.
barokinesis, barokinetic
A change of linear or angular velocity (movement) in response to a change in pressure.
A specialist in the study of weight or gravity.
The study of weight or gravity.
In medicine, a device for measuring the weight and length of infants.
1. An instrument for measuring atmospheric pressure; used in determining height above sea level and predicting changes in the weather.
2. Anything that reflects or indicates change; such as, breadlines are a barometer of unemployment.
Describing information derived from the use of a barometer.
The science that deals with the use of the barometer and making barometric observations.
The scientific study of the measurement of atmospheric pressure.
barophile (s) (noun), barophiles (pl)
An organism that grows under conditions of high atmospheric pressure: One example of an obligate barophile is the Halomonas salary which is a gram-negative proteobacteria and requires a pressure of 1000 atm.
barophilic (adjective), more barophilic, most barophilic
1. In microbiology, relating to or describing a microorganism that grows optimally at high atmospheric pressure: Some deep-sea bacteria are barophilic in that they thrive especially well in the very low layers of the ocean.
2. Regarding a living form that thrives under conditions of high hydrostatic pressure: Some barophilic organisms grow in an ocean depth of 1000 fathoms where there is little or no light.
barophobia (s) (noun), barophobias (pl)
An irrational fear of the force of gravity: Barophobia involves the terror that someone has of the earth's powerful effect of pulling or drawing down, as if he or she were falling, especially when one is overweight.
1. In general, any sensor of pressure changes.
2. Sensory nerve ending in the wall of the auricles of the heart, vena cava, aortic arch, and carotid sinus, sensitive to stretching of the wall resulting from increased pressure from within, and functioning as the receptor of central reflex mechanisms that tend to reduce that pressure.
1. A reflex triggered by stimulation of a baroreceptor.
2. The reflex responses to a stimulation of baroreceptors of the carotid sinus and aortic arch, regulating blood pressure by controlling heart rate, strength of heart contractions, and diameter of blood vessels.
