Shifts in
rainfall patterns and shorelines will contribute to mass migrations on a
scale never before seen
Consequently, there are grave concerns that the
rainfall patterns altered by climate change could trigger a forest decline on a global
scale.
So apparently you're suggesting that decadal -
scale precipitation
patterns (more, less
rainfall) and temperature changes are better explained by atmospheric CO2 concentrations.
«Researchers working at the Australian National University Research School of Earth Sciences have discovered century -
scale patterns in Pacific
rainfall and temperature, and linked them with global climate changes in the past 2000 years.
«Lehmann et al. (2015) also found large —
scale increasing
patterns in extreme precipitation, with 12 % more record - breaking
rainfall events over 1981 — 2010.
«Heat escaping from the ocean through polynyas impacts the large -
scale energy budget of the ocean and atmosphere, cloud
patterns, and even
rainfall...»
For example, the Hadley cell, the large -
scale pattern of atmospheric circulation that transports heat from the tropics to the subtropics, has marched south during recent decades, moving the subtropical dry zone (a band that receives little
rainfall) along with it.
Forests are the only carbon capture and storage «technology» we have in our grasp that is safe, proven, inexpensive, immediately available at
scale, and capable of providing beneficial ripple effects — from regulating
rainfall patterns to providing livelihoods to indigenous communities.»
Overall, we find that the CTL simulation in the low resolution CESM captures the larger -
scale patterns of seasonal
rainfall and its variability associated with ENSO reasonably well.
Interviews with indigenous communities indicate that
rainfall patterns and river levels are changing, and the minor fires traditionally used for small -
scale rotational agriculture are more difficult to control.
Large -
scale changes in savanna vegetation cover may also feed back to regional
rainfall patterns.
It is further argued that the transition of vertical circulation
patterns is in response to adjustments to geostrophic imbalance — an adjustment time
scale of 6 — 9 h. Although unproven, we suggest that antecedent
rainfall over the alkali desert 2 weeks prior to the event was instrumental in lowering the bulk density of sediments and thereby improved the chances for dust ablation by the atmospheric disturbance.
In summary, in contrast with the simulations of extreme temperature by climate models, extreme precipitation is difficult to reproduce, especially for the intensities and
patterns of heavy
rainfall which are heavily affected by the local
scale (see Chapter 10).
