| Definition | 'Mass fraction' is used in the construction mass_fraction_of_X_in_Y, where X is a material constituent of Y. It means the ratio of the mass of X to the mass of Y (including X). A chemical or biological species denoted by X may be described by a single term such as 'nitrogen' or a phrase such as 'nox_expressed_as_nitrogen'. In an atmosphere model, stratiform cloud is that produced by large-scale convergence (not the convection schemes). The specification of a physical process by the phrase due_to_process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. 'cloud_microphysics' is the sum of many cloud processes such as condensation, evaporation, homogeneous nucleation, heterogeneous nucleation, deposition, sublimation, the Bergeron-Findeisen process, riming, accretion, aggregation and icefall. The precise list of processes that are included in 'cloud_microphysics' can vary between models. Where possible, the data variable should be accompanied by a complete description of the processes included, for example, by using a comment attribute. Standard names also exist to describe the tendencies due to the separate processes. "tendency_of_X" means derivative of X with respect to time. | |
