However, this link between climate warming and heavy rainfall has only been examined in particular regions
where moisture availability is relatively high.
This decrease in mean rainfall occurs despite an increase in seasonal mean low - level moisture convergence and convective available potential energy expected from increased
moisture availability in response to atmospheric warming.
Until now, no research has been undertaken that examines this relationship in dryland regions where short, sharp rainstorms are the dominant source of precipitation and where
moisture availability on land is extremely limited.
Ultimately, in forests not otherwise limited by energy or nutrients variability in
moisture availability with natural and climate oscillations may drive establishment success between years (League and Veblen 2006), with indirect disturbance effects (e.g., fires, landslides, insect outbreaks, and pathogen attacks) greatly affecting long - term recruitment success (Clark et al. 2016).
«The result,» Brenner says, «appears to be that climate factors,
especially moisture availability, determine whether C3 or C4 plants dominate in an area, not CO2.»
This may be due to
decreased moisture availability at these temperatures, though Westra et al. note that «the mechanism that causes these moisture deficits remains to be investigated.»
If you do, perhaps I should point out that the slow response to scarring by solid ice is directly connected to the question of snowpack depth and the fast response to summer
soil moisture availability.
Rosanne D'Arrigo, senior research scientist at the Tree Ring Lab at Columbia University «s Lamont - Doherty Earth Observatory, hypothesises that «beyond a certain threshold level of temperature the trees may become more stressed physiologically, especially
if moisture availability does not increase at the same time.»
The map just shows the potential climate zone change and does not take into account soil type (or even if there is soil), topography, and
moisture availability, yet many people simply take it, and other similar maps and assertions, at face value.
