Task: Instance Description Understanding (ontology: Earth_Environment/SWEET)

Which of the following definitions best describes the instance 'pseudoadiabatic'?

A. A process in which a system does not interact with its surroundings by virtue of a temperature difference between them.
B. A system or flow that evolves slowly in time compared to the rotation period of the earth, has a length scale of the deformation radius or larger, and undergoes only limited vertical excursions.
C. A moist-adiabatic process in which the liquid water that condenses is assumed to be removed as soon as it is formed, by idealized instantaneous precipitation.
D. the instance climate classification, also known as the polar marine climate classification, is characterized by all months having temperatures above -7 degree C, warmest month above 0 degree C, and annual temperatures less than 17 degree C.

Answer: A moist-adiabatic process in which the liquid water that condenses is assumed to be removed as soon as it is formed, by idealized instantaneous precipitation.
