Sentences with phrase «hydrological variables»

Anyway, there is so much documented evidence of spurious shifts and trends in hydrological variables in the reanalyses (and even in temperature and wind) that I would not place any more store in trends from them than I would in a Ouija board.

Although water storage and soil moisture are difficult to observe with sufficient spatial coverage, observational reconstructions of land hydrological variables and fire cycles (Maurer et al. 2002; van den Dool et al. 2003; Fan and van den Dool 2004; Littell et al. 2009; Wada et al. 2010) may still provide useful information to determine potential longer - term predictabilities.

I indeed used the generalized entropy to describe the marginal distribution of hydrological variables, after having failed with standard entropy, particularly on the distribution tail.

Probabilistic approaches are rare, with the exception being the effects of uncertainty in alternative representations of land - use change for hydrological variables (Eckhardt et al., 2003).

Relatively little detailed work has compared such reanalysis data with independent observed data sets (see Santer et al., 1999, and Widmann and Bretherton, 2000, for two exceptions), but it is known that certain reanalysis variables - such as precipitation and some other hydrological variables - are unreliable.

The surface hydrological variables are more difficult to observe and analyse than surface temperature.

Evaluations such as presented or referenced above show that use of ERA - Interim to provide prompt monthly summaries of several hydrological variables in terms of anomaly maps and time series is on quite firm ground for Europe, including sub-divisions between west and east, and north and south.

The variation over time of the hydrological variables and temperature are shown below for averages over land areas for NW, NE, SW and SE Europe.

Moreover, we show that multidecadal variations exist in other hydrological variables (evapotranspiration, snow cover, and soil moisture).

We employ the Variable Infiltration Capacity (VIC) process - based hydrological model driven by gridded observations to investigate the key controlling factors of anomalous APF events in the FRB and four of its subbasins that contribute more than 70 % of the annual flow at Fraser - Hope.

However, despite all that, the weather systems combined with the hydrological cycle and the global air circulation guided by the sea surface temperatures do provide reasonable overall stability for eons at a time by neutralising many potentially disruptive natural and biologically induced variables affecting air temperature.
