Precipitation does
decrease soil moisture goes up; winds change, so depending upon the location, wind effect will influence shading... partially.
Model projections suggest that although increased temperature and
decreased soil moisture will act to reduce global crop yields by 2050, the direct fertilization effect of rising carbon dioxide concentration -LRB-[CO2]-RRB- will offset these losses.
At the local scale, high temperatures may lead to increased evaporation and
decreased soil moisture, resulting in an «agricultural drought».
The climate models project
decreased soil moisture in much of the U.S. in both summer and winter.
With climate warming, it is likely that boreal fires will increase due to a shorter duration of the seasonal snowpack and
decreased soil moisture (Kasischke et al., 1995).
Not exact matches
Mono - cropping exposes the
soil surface allowing faster transpiration rate and reducing
moisture, in the context of rubber plantations the rubber tappers suffered most since there is a significant reduction of
moisture there is a dramatic
decrease in sap supply of rubber trees.»
The Warming Meadow's radiators raise average
soil temperatures by about three degrees Fahrenheit,
decrease growing season
soil moisture by up to twenty percent and advance the spring snowmelt date by up to a month in order to simulate predicted effects of climate change.
In their upcoming second Ecological Restoration publication titled «Resurgence of Native Plants After Removal of Amur honeysuckle from Bender Mountain Preserve,» Conover and Sisson reveal the lengths to which honeysuckle alters habitats by
decreasing light availability and depleting
soil moisture and nutrients, as well as by possibly releasing toxic chemicals that prevent other plant species from growing in the vicinity.
Overall, the antioxidant content increased and fat content of the beans
decreased during the dry season as temperatures rose and
soil moisture dropped.
Rather than focusing just on lower rainfall, the team measured three types of drought as they affect Jordan: rainfall
decrease, agricultural
soil moisture loss and declines in freshwater streams.
For example, in years that had more than average burning during the dry season, measurements of
soil moisture, evaporation and vegetation greenness — all of which help to trigger rain —
decreased in the following wet season.
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.
Decreased cloudiness allowed more solar radiation to reach the plants, which typically promotes photosynthesis, but in this case it likely posed an extra stress on the plants from the resulting depletion of
soil moisture.
Studies show that
soil moisture retention in most years did not significantly
decrease with the presence of these crops (Miller et al. 2006; Miller and Holmes 2012), suggesting that this revenue - generating crop can replace a fallow year without incurring a
moisture deficit.
A: Eric Holthaus Meteorologist Slate: As far as North America is concerned,
soil moisture is expected to
decrease virtually everywhere except the high Canadian Arctic and Alaska over the next several decades.
The
decreasing rainfall (shown in the top graph below) combined with rising temperatures (second graph) resulted in a decline in
soil moisture (third graph), the researchers say.
peat unconsolidated
soil material consisting largely of partially decomposed organic matter accumulated under conditions of excess
moisture or other conditions that
decrease decomposition rates
Even in areas where precipitation does not
decrease, these increases in surface evaporation and loss of water from plants lead to more rapid drying of
soils if the effects of higher temperatures are not offset by other changes (such as reduced wind speed or increased humidity).5 As
soil dries out, a larger proportion of the incoming heat from the sun goes into heating the
soil and adjacent air rather than evaporating its
moisture, resulting in hotter summers under drier climatic conditions.6
The study finds that wind turbines elevated both day and night temperatures, which suppressed
soil moisture and enhanced water stress,
decreasing local vegetative growth and productivity.
-- «The 2012 report on extreme events by the Intergovernmental Panel on Climate Change examined the evidence for regional changes in
soil moisture since 1950, and made the following assessment for western North America: «No overall or slight
decrease in dryness since 1950; large variability; large drought of the 1930s dominates.»
Amazon forest loss drives significant increases in precipitation from Dec - May (April excluded, Fig 3F), which corresponds temporally to increased
soil moisture saturation and
decreases in later, growing season limitations.
But to make things worse, climate scientists predict that between 2080 and 2099,
soil moisture will
decrease by between 5 % and 15 % worldwide.
Soil moisture shows a
decreasing trend over the 1979 - 2017 period and all seasons of 2017 showed below average values.
We can also think about hydrological drought, or how
decreased precipitation affects streamflow,
soil moisture, reservoir and lake levels, and groundwater recharge.
The greatest increase in the 20 - year return values of daily maximum temperature (Figure 9.29, top) is found in central and southeast North America, central and south - east Asia and tropical Africa, where there is a
decrease in
soil moisture content.
In contrast, increased thaw depth and increased water - use efficiency under elevated CO2 will tend to increase available
soil moisture,
decreasing fire frequency and increasing woody biomass.
The impacts of runoff and
soil moisture deficits associated with warm temperatures can be acute, including enhanced wildfire risk (21), land subsidence from excessive groundwater withdrawals (22),
decreased hydropower production (23), and damage to habitat of vulnerable riparian species (24).
Generally, NUE increases as
soil moisture increases and
decreases as N applied increases, Gauer et al. (1992), Campbell et al. (1993).
(Both cause plant cover to
decrease which causes
soil moisture decreases often making storms less frequent, less regular, less predictable and more intense, further
decreasing plant cover, reducing or killing crops, eroding
soil (leading to
decreased fertility, water pollution, etc.) and spiraling down into desertification and the creation of wasteland from what had been a fertile, verdant landscape.
«Clouds, which largely determine the geographic patterns of DTR, greatly reduce DTR by sharply
decreasing surface solar radiation while
soil moisture decreases DTR by increasing daytime surface evaporative cooling.
But by April 2006 there was a sharp reduction in productivity, coinciding with a
decrease in
soil moisture.
