We study the evolution of dynamic fluctuations averaged over different spacelengths and time scales to characterize spatially and temporally heterogeneousbehavior of TIP4P/2005 water in liquid and supercooled states. Analysing amillion particle simulated system we provide evidence of the existence, uponsupercooling, of a significant enhancement of spatially localized dynamicfluctuations stemming from regions of correlated mobile molecules. We show thatboth the magnitude of the departure from the value expected for the system-sizedependence of an uncorrelated system and the molecular size at which suchtrivial regime is finally recovered clearly increase upon supercooling. Thisprovides a means to estimate an upper limit to the maximum length scale ofinfluence of the regions of correlated mobile molecules. Notably, such upperlimit grows two orders of magnitude on cooling, reaching a value correspondingto a few thousand molecules at the lowest investigated temperature.
