accumulated temperature A surplus or deficit of temperature with respect to a defined mean value and expressed as an accumulation over a given period (e.g. a month, season, or year). For example, a datum value of 6°C is used as a critical temperature for sustained vegetation growth, against which accumulated surpluses or deficits may be measured.
