But this claim is discredited by University of Washington climatologist Cliff Mass, who after examining precipitation levels in the Gulf found that «[t] here is no evidence that global warming is influencing Texas coastal precipitation in the long term and little evidence that warmer than normal temperatures had any real impact on
the precipitation intensity from this storm.»
Observed changes in short term
precipitation intensity from previous research and the anticipated changes in flood frequency and magnitude expected due to enhanced greenhouse forcing are not generally evident at this time over large portions of the United States for several different measures of flood flows.
Not exact matches
Given the revised timeline in this region, Willenbring and colleagues determined that the increased
precipitation resulted
from changes in the
intensity of the sun's radiation on the Earth, which is based on the planet's tilt in orbit.
He cited a recent analysis by scientists
from the National Climatic Data Center that confirmed earlier studies showing a substantial increase already in the
intensity of
precipitation across the United States, interspersed by longer dry spells.
«Century of Data Shows Intensification of Water Cycle but No Increase in Storms or Floods Released: 3/15/2006 12:13:21 PM» (excerpt) A review of the findings
from more than 100 peer - reviewed studies shows that although many aspects of the global water cycle have intensified, including
precipitation and evaporation, this trend has not consistently resulted in an increase in the frequency or
intensity of tropical storms or floods over the past century.
No matter the probability or
intensity of USGS ARkStorm it would have to drop
precipitation (not snowpack which melts slower) where the watersheds are for the 10 dams in Northern California shown on the map at the following link (the 2 dams in Southern California only receive water
from the Northern Cal dams and should not be considered): Link
As I explained above — major dams are designed by a different method of estimating probable maximum
precipitation from recorded high
intensity storm
precipitation transformed by local and regional factors including moisture availability.
America's WETLAND Foundation Restore - Adapt - Mitigate: Responding To Climate Change Through Coastal Habitat Restoration PDF Coastal habitats are being subjected to a range of stresses
from climate change; many of these stresses are predicted to increase over the next century The most significant effects are likely to be
from sea - level rise, increased storm and wave
intensity, temperature increases, carbon dioxide concentration increases, and changes in
precipitation that will alter freshwater delivery.....
The colour field underneath the wind arrows shows the
precipitation rate on a scale
from 0 to 20 mm per hour, noting that peaks in rainfall
intensity (which may have been far higher than 20 mm / hr at times in localised regions within the Hurricane circulation), are not resolved in this animation.
From an observational perspective then, key issues are the tropical storm formation regions, the frequency,
intensity, duration and tracks of tropical storms, and associated
precipitation.
Because
precipitation comes mainly
from weather systems that feed on the water vapour stored in the atmosphere, this has generally increased
precipitation intensity and the risk of heavy rain and snow events.
A growing body of evidence
from the most prominent of the hyperthermals, the Paleocene Thermal Maximum (PETM; ~ 56 Ma), points toward a major mode shift in the
intensity and patterns of
precipitation.
Key findings
from these experiments include: fewer tropical cyclones globally in a warmer late - twenty - first - century climate (Figure 8), but also an increase in average cyclone
intensity, the number and occurrence days of very intense category 4 and 5 storms in most basins (Figure 9) and in tropical cyclone
precipitation rates (Figure 10).
