paraphrase

• This event was widely described in the media as a “heat dome”, wherein
  • subsidence/adiabatic warming,
  • “trapped air”, and
  • sensible heating
• are the dominant mechanisms driving the anomalous heat.
• This conceptual model ignores the role of upstream diabatic heating,
  • which our analysis
• shows is a significant heat source.
• This “heat dome” phrase is not a common phrase within the scientific community

comment

• the authors do not refer to this event as a heat dome, as is popularly used in the media because diabatic heating was involved
