Morphology
The phrase is fully compositional: the adjective 'barometric' (relating to barometers/atmospheric measurements) simply specifies the kind of 'pressure', so the combined meaning is 'atmospheric pressure' or pressure measured by a barometer. This is a non-idiomatic, productively formed technical compound found across languages, so a learner who knows the constituents can infer the meaning.
Etymology
Barometric pressure comes from the tool barometer and the word pressure. A barometer shows how hard the air pushes down; when the air pushes harder the number goes up and when it pushes less the number goes down, so the phrase means 'the pressure of the air'.
