Within this framework, HIST minus NAT is the thermodynamic trend component, NAT supplies the dynamic trend under fixed forcing, and PD minus NAT tests how dynamic conditions modulate thermodynamic responses.

Because the simulations have nearly identical large-scale circulation dynamics, differences among them represent thermodynamic effects and circulation’s modulation of those effects.
The time-evolving thermodynamic response is defined as HIST minus NAT, while PD minus NAT is used to analyse thermodynamic-component variability arising from modulation by dynamic conditions.
The study defines the thermodynamic trend component as HIST minus NAT and the dynamic component as the trend in NAT, where external forcing is fixed.
