Modest and slowly evolving changes in the width of the Hadley Cell could force
rapid changes in precipitation in transition regions that lie between the subtropical deserts and tropical rainforests (e.g., the Sahel).
For example, a relatively slow shift in the distribution of precipitation could give rise to relatively
rapid changes in precipitation patterns in regions that lie at the interface of dry and rainy regions (see Figure 2.8), potentially altering a location's local climate with possible ramifications to water supplies and / or agriculture for example.
Not exact matches
Climate
change is having a dramatic impact on Earth's biodiversity, by causing
rapid fluctuations
in temperature and
precipitation that alter species» environments.
Daniel Swain and colleagues model how the frequency of these
rapid, year - to - year transitions from extreme dry to wet conditions — which they dub «
precipitation whiplash events» — may
change in California's future as a consequence of man - made warming.
Other likely consequences (e.g.
rapid dynamical sea level
changes, shift
in the inter-tropical convergence zone and hence tropical
precipitation patterns) are discussed
in the Rahmstorf and Zickfeld editorial essay mentioned above, and the references therein.
Diarrheal diseases have also been found to occur more frequently
in conjunction with both unusually high and low
precipitation.93, 94 Sporadic increases
in streamflow rates, often preceded by
rapid snowmelt95and
changes in water treatment, 96 have also been shown to precede outbreaks.
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
They also captured
rapid changes in wind speed that occur around the eye of the cyclone, which did not appear to be affected by any data loss, like what can be caused by heavy
precipitation in other satellite data.
Individual drivers of climate
change initially alter the energy budget of the atmosphere leading to distinct
rapid adjustments involving
changes in precipitation.
Ecological surprises include
rapid and abrupt
changes in temperature and
precipitation, leading to an increase
in extreme events such as floods, fires and landslides, increases
in eutrophication, invasion by alien species, or
rapid and sudden increases
in disease (Carpenter et al., 2005).
