  text: 'While the importance of ecosystem functioning is undisputed in the context
    of climate change and Earth system modeling, the role of short‐scale temporal
    variability of hydrometeorological forcing (~1 h) on the related ecosystem processes
    remains to be fully understood. Various impacts of meteorological forcing variability
    on water and carbon fluxes across a range of scales are explored here using numerical
    simulations. Synthetic meteorological drivers that highlight dynamic features
    of the short temporal scale in series of precipitation, temperature, and radiation
    are constructed. These drivers force a mechanistic ecohydrological model that
    propagates information content into the dynamics of water and carbon fluxes for
    an ensemble of representative ecosystems. The focus of the analysis is on a cross‐scale
    effect of the short‐scale forcing variability on the modeled evapotranspiration
    and ecosystem carbon assimilation. Interannual variability of water and carbon
    fluxes is emphasized in the analysis. The main study inferences are summarized
    as follows: (a) short‐scale variability of meteorological input does affect water
    and carbon fluxes across a wide range of time scales, spanning from the hourly
    to the annual and longer scales; (b) different ecosystems respond to the various
    characteristics of the short‐scale variability of the climate forcing in various
    ways, depending on dominant factors limiting system productivity; (c) whenever
    short‐scale variability of meteorological forcing influences primarily fast processes
    such as photosynthesis, its impact on the slow‐scale variability of water and
    carbon fluxes is small; and (d) whenever short‐scale variability of the meteorological
    forcing impacts slow processes such as movement and storage of water in the soil,
    the effects of the variability can propagate to annual and longer time scales.'
