Sentences with phrase «soil moisture variations»

Most previous studies mainly focused on how moisture in soil responds to amounts of precipitation, but are we missing an important factor that can explain soil moisture variations in general?

Applying the framework of Delworth and Manabe (1988) to the more complex CESM system, we compare simple red noise null hypothesis models for soil moisture variations at various depth levels with an ensemble of perfect model forecasts conducted with the CESM.

The second part of our study (Sect. 4) focuses on the effects of soil moisture variations on North American vegetation and wildfire occurrences.

Unresolved issues that will be addressed in a series of forthcoming studies include the effects of ocean dynamics on the predictability of low - frequency atmosphere and land variability and the feedback of soil moisture variations on atmospheric temperatures and circulation (e.g., Rowntree and Bolton 1983; Atlas et al. 1993; Koster et al. 2000).

Not exact matches

It is found that the performance of NB sensors is strongly limited by the presence of the soil moisture and by its small - scale variations.

In contrast to core areas of interior forest, non-interior forest edge areas are subject to impacts from invasive species, pollution, and variation in soil moisture, for example.

The daily leaf - thickness variations were minor, with no significant day - to - day changes when soil moisture contents ranged from high to wilting point.

The daily electrical - capacitance variations decreased when soil moisture was below the wilting point and completely ceased below the soil volumetric water content of 11 percent, suggesting that the effect of water stress on electrical capacitance was observed through its impact on photosynthesis.

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

Depending on the region, the persistence from spring to summer of soil moisture or snow anomalies generated during spring by temperature and precipitation variations may explain river flows variations in summer, when no concomitant climate variations exist.

Murry Salby who is suggesting that ocean and soil moisture data shows that the observed rise in atmospheric CO2 might well be entirely from natural causes and Roy Spencer who suggests that variations in oceans and sun affecting global cloudiness make it impossible to verify the sign of the climate system response to more CO2 in the air.

Evaluation of C3S satellite soil moisture against sets of ground - based measurements shows that it captures temporal dynamics, but with large variations in quality through space and time (Dorigo et al. 2017, Dorigo et.

As a result of soil and atmosphere feedbacks (Beljaars et al. 1996; Seneviratne et al. 2010), seasonal predictions of soil moisture content over the US can further increase the predictability of precipitation and atmospheric temperature variations for up to several months (Zeng et al. 1999; Kanamitsu et al. 2003; Koster and Suarez 2003; Yang et al. 2004; Dirmeyer et al. 2013).

Furthermore, the CO2 variations did not correlate with anthropogenic emissions, but with temperature and soil moisture.

So they knew that 93 % of interannual variation in CO2 could be explained by natural responses to temperature and soil moisture content, yet they continued with the charade?

Now, however, researchers from China, France and Switzerland have found that including information about precipitation frequency may also significantly improve our ability to explain variations of moisture in summer soil.
