Not exact matches

Current climate change models indicate temperatures will increase as long as humans continue to emit greenhouse gases into the atmosphere, but the projections of future precipitation are far less certain.

«Our results indicate that these glaciers may be highly sensitive to changes in temperature, and that increases in precipitation are not enough to offset the increased melt,» Shea explained.

These variability trends indicate that the frequency of extremes (more drought events and more heavy precipitation events) has increased whereas the mean has remained approximately the same.

The report, «Atmospheric Warming and the Amplification of Precipitation Extremes,» previewed in Science Express this Thursday, August 7, and published in an upcoming issue of Science, found that both observations and models indicated an increase in heavy rainstorms in response to a warmer climate.

Tropical land - surface precipitation measurements indicate that precipitation likely has increased by about 0.2 to 0.3 % / decade over the 20th century, but increases are not evident over the past few decades and the amount of tropical land (versus ocean) area for the latitudes 10 ° N to 10 ° S is relatively small.

Nonetheless, direct measurements of precipitation and model reanalyses of inferred precipitation indicate that rainfall has also increased over large parts of the tropical oceans.

Our observational studies (Gray and Schwartz, 2010 and 2011) of the variations of outward radiation (IR + albedo) energy flux to space (ISCCP data) vs. tropical and global precipitation increase (from NCEP reanalysis data) indicates that there is not a reduction of global net radiation (IR + Albedo) to space which is associated with increased global or tropical - regional rainfall.

In commenting on their findings, the three researchers write that «the large number of stable glacier termini and glacier advances is influenced by positive glacier mass balances in the central Karakoram during the last decade,» citing Gardelle et al. (2012, 2013) and Kaab et al. (2012), which they indicate is «induced by increasing winter precipitation and decreasing summer temperatures since the 1960s,» citing Archer and Fowler (2004), Williams and Ferrigno (2010), Bolch et al. (2012), Yao et al. (2012) and Bocchiola and Diolaiuti (2013).

The results indicate that extreme precipitation events consistently increase by the middle of the twenty - first century for all return periods (49 — 52 %), but changes may become more profound by the end of the twenty - first century (81 — 101 %).

Snowfall varies across the region, comprising less than 10 % of total precipitation in the south, to more than half in the north, with as much as two inches of water available in the snowpack at the beginning of spring melt in the northern reaches of the river basins.81 When this amount of snowmelt is combined with heavy rainfall, the resulting flooding can be widespread and catastrophic (see «Cedar Rapids: A Tale of Vulnerability and Response»).82 Historical observations indicate declines in the frequency of high magnitude snowfall years over much of the Midwest, 83 but an increase in lake effect snowfall.61 These divergent trends and their inverse relationships with air temperatures make overall projections of regional impacts of the associated snowmelt extremely difficult.

Both (top right and bottom left) indicate that heavy precipitation events will increase in intensity in the future across the Midwest.

Although there is as yet no convincing evidence in the observed record of changes in tropical cyclone behaviour, a synthesis of the recent model results indicates that, for the future warmer climate, tropical cyclones will show increased peak wind speed and increased mean and peak precipitation intensities.

A declining ratio indicates that greater percentages of precipitation occur as rain instead of snow and / or that melt of winter snowpack is increasing.

Output from global circulation models indicates that climate variability will continue to be an important characteristic of the region in the future [52], but that climate change may increase the risk of extreme climatic events such as multi-decade droughts and extreme winter precipitation [53], [54].

Since models indicate and observations appear to also indicate an increase in precipitation, perhaps they should be arguing for more CO2 release in order to provide more freshwater to the continents.

The singular spectral analysis and monthly sequential Mann - Kendall test of the temperature and precipitation for 1992 - 2011 indicated that the temperature has increased about +0.03 C a1 but statistically significant only for winter months.

Glacier mass balance modelling indicates that to compensate for the increased ablation from a temperature rise of 1 °C a precipitation increase of 20 % (Oerlemans, 1981) or 35 % (Raper et al., 2000) would be required.

While there has been a recent increase in the number of landfalling US hurricanes, the increase in tropical cyclone - associated heavy events is much higher than would be expected from the pre-1994 association between the two, indicating that the upward trend in heavy precipitation events is due to an increase in the number of heavy precipitation events per system.

Our results indicate that these glaciers may be highly sensitive to changes in temperature, and that increases in precipitation are not enough to offset the increased melt.»

Specifically, both observations and GOGA indicate increased precipitation to the northeast of New Zealand extending to 30 ° S.

The projections also indicate an increase in the basin - averaged precipitation and an increase in the frequency of extreme precipitation events over the region as a whole.

«Our ongoing modeling analysis (manuscript in preparation) indicates that the sum of winter rain in California will actually increase given the increasing CO2,» Wang said, «but the precipitation fluctuation will also increase — wet gets wetter and dry gets drier.»

The studies indicate that the observed pattern of mid-tropospheric warming in recent decades over west central Asia led to an increase in instability of the western winds thereby increasing WDs leading to a higher propensity for heavy precipitation over the western Himalayas.

«Indeed it is estimated that annual mean temperature has increased by over 2 °C during the last 70 years and precipitation has decreased in most regions, except the western part of the country, indicating that Mongolia is among the most vulnerable nations in the world to global warming.»

-- First we increase the greenhouse gases — then that causes warming in the atmosphere and oceans — as the oceans warm up, they evaporate more H2O — more moisture in the air means more precipitation (rain, snow)-- the southern hemisphere is essentially lots of water and a really big ice cube in the middle called Antarctica — land ice is different than sea ice — climate models indicated that more snowfall would cause increases in the frozen H2O — climate models indicated that there would be initial increases in sea ice extent — observations confirm the indications and expectations that precipitation is increasing, calving rates are accelerating and sea ice extent is increasing.
