Sentences with phrase «soil hydrological changes»

Not exact matches

Although these hydrological changes could potentially increase soil water availability in previously snow - covered regions during the cool low - ET season (34), this effect would likely be outweighed by the influence of warming temperatures (and decreased runoff) during the warm high - ET season (36, 38), as well as by the increasing occurrence of consecutive years with low precipitation and high temperature (Fig. 4A).

From a geological standpoint, the soil / permafrost / hydrological changes might be really interesting.

As noted in the TAR (McAvaney et al., 2001), vegetation change during the mid-Holocene likely triggered changes in the hydrological cycle, explaining the wet conditions that prevailed in the Sahel region that were further enhanced by ocean feedbacks (Ganopolski et al., 1998; Braconnot et al., 1999), although soil moisture may have counteracted some of these feedbacks (Levis et al., 2004).

When done so, proxy records and climate models indicate that the response to past global warming was profound, with evidence for global reorganisation of the hydrological cycle and profound local increases and decreases in rainfall; combined with elevated temperatures and terrestrial vegetation change, this appears to often result in warming - enhanced soil organic matter oxidation, chemical weathering and nutrient cycling.
