under atmospheric pressure vs under the atmospheric pressure

Both phrases are correct, but they are used in different contexts. 'Under atmospheric pressure' is more commonly used and refers to being subject to the pressure exerted by the atmosphere. 'Under the atmospheric pressure' is less common and would be used when specifically referring to the pressure of a particular atmosphere, such as Earth's atmosphere.
