Esempio di traduzione dall'inglese tratto da Meterology for Mariners (Meteorological Office, HMSO, 1996)
The atmosphere surrounds the whole surface of the earth, both land and sea. Just as life in the depth of the ocean is subjected to a pressure owing to the weight of the sea above, so all of us, whether on land or sea, are living at the bottom of an ocean of air and are subjected to a pressure exerted by the weight of air above us. At sea level this pressure is about 1 kilogram per square centimetre. If we ascend a mountain or go up in an aeroplane, the pressure we experience at the new level is reduced, since the weight of air below our new level no longer contributes to the pressure exerted on us. Our bodies are adapted to the sea-level pressure of the atmosphere so that we are not conscious of it, but when we make a rapid ascent as in an aeroplane the reduced pressure affects the eardrums and renders breathing difficult owing to the reduction in the quantity of oxygen available in a given volume of air. An increase of elevation from sea level to 1 kilometre will decrease the pressure of about 100 grams per square centimetre, but the rate of decrease becomes less at higher levels.
L’intera superficie terrestre, la terraferma come il mare, è circondata dall’atmosfera.
