Preliminary results of an analysis of rising temperature effects on three major river systems in the western United States — the Columbia, the Sacramento, and the Colorado — indicate that the winter snow pack in the mountains feeding them will be dramatically reduced and that winter rainfall and flooding will increase.

The CSIRO projections are for an INCREASE of 1.5 % (low global warming scenario) and 3.5 % (high warming scenario) in rainfall in summer and autumn; and for a DECREASE of 3 % (low global warming scenario) and 7.5 % (high global warming scenario) in winter and spring.

Let's say for example, that we have a scenario in SE Aust where summer and autumn rainfall increase by +5 % and winter - spring decreases by -5 %.

The summer rainfall will have little effect on streamflow and the winter spring - rainfall will lead (with increases in evaporative demand) to a decrease in streamflow of > 10 %.

Scientists expect more intense storms to occur in the Midwest throughout the year, and more precipitation to fall in winter and spring.4 If our carbon emissions continue to rise at current rates, spring rainfall in Jefferson City is projected to increase 25 percent or more by the end of this century.9, 10

The AMV warming also leads to reduced rainfall over the western part of the US and Mexico and to a weak increase in rainfall over Europe during boreal winter (see figure).

Australian winter and spring rainfall generally increases in negative IOD years, and decreases in positive IOD years.

NOAA scientists have developed a new high - resolution climate model that shows southwestern Australia's long - term decline in fall and winter rainfall is caused by increases in manmade greenhouse gas emissions and ozone depletion, according to research published today in Nature Geoscience.

On the upside, increased rainfall this winter enabled California's Department of Water Resources to announce in April that it is boosting water delivery to meet 60 percent of requests through the 2016 calendar year — up from 20 percent last year and 5 percent in 2014.

In addition, the pattern of sea surface temperatures at low latitudes is extremely important for regional climate variations (shown, for example, by the increased likelihood of heavy winter rainfall in California when the eastern tropical Pacific warms in El Niño events).

Jeff Knight said: «Our analysis shows that climate change likely did make a contribution to the record rainfall in 2013 - 14 through a long - term increase in UK winter rainfall that is not associated with changing weather patterns.

If global temperatures were to rise by twice that amount, the benefits would far outweigh the downsides in terms of improved crop growth, lower morbidity due to milder winters, increased rainfall, and so on.

Some of the predicted impacts of climate change include: increased variability in both monsoon and winter rainfall patterns; increases [continue reading...]

Climate change already is being felt in the form of warmer winters in New York over the last several decades and increasing numbers of extreme rainfall events, according to DeGaetano, the Cornell researcher, who is the director of the Northeast Regional Climate Center at Cornell.

Under extreme deforestation scenarios, disappearance of the Amazon rainforest would reduce rainfall in the American Midwest, Northwest and South at key growing times, while increasing winter precipitation along the eastern seaboard.

In particular, over NH land, an increase in the likelihood of very wet winters is projected over much of central and northern Europe due to the increase in intense precipitation during storm events, suggesting an increased chance of flooding over Europe and other mid-latitude regions due to more intense rainfall and snowfall events producing more runoff.

For example, increased rainfall during a shorter period in winter still could lead to reduced levels in summer in river flows, lakes, wetlands, and thus in freshwater fisheries.
