Sentences with phrase «with less precipitation»

It seems clear to me that the sentence is about responses to a shift from one climate regime, the recent past and present day, to another, with less precipitation, in the future (it is the IPCC climate change impacts report after all, and they do say `... not necessarily producing gradual changes between the current and the future situation»).

As water quantities slow with less precipitation, a concentration of nutrients and sediments reduces the water quality.

The chart's green curve indicates that those periods with less precipitation (i.e. droughts) are more common when cooler temps prevail - more arid conditions, with less food production make people (and societies) rather restless.

For example, in Southern California, tropical widening may be associated with less precipitation.

In that case (along with greater precipitation, and the precipitation belt moving to higher latitudes), there could be more snow in the winter & greater melting in the summer (in higher latitudes), while I'd think the lower latitudes (with less precip) and the local mean temp being higher, would melt the glaciers faster, without adequate snowfall & low winter temps to slow this glacial decrease.

The result is that there is no difference in regional cloud cover trends, neither of precipitation, with increasing contamination and that the contaminated area has more dimming, but warmed more than the less contaminated area.

Based on these figures, I suppose that the West Greenland ice melting was larger in the 1930 - 1950 period than in the 1985 - 2005 period...

4) Actually, Antarctica (168 mm year continental average) does recieve less precipitation than the Arctic (< 500 mm per year average), with the highest most central regions of Antarctica receiving 50 mm per year compared to < 100 to 200 mm per year for central Greenland (described as the driest part of the Arctic).

It would result in a * reduced * rate of cooling with height and therefore, arguably, less precipitation.

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.

For the entire Northern Hemisphere, there is evidence of an increase in both storm frequency and intensity during the cold season since 1950,1 with storm tracks having shifted slightly towards the poles.2, 3 Extremely heavy snowstorms increased in number during the last century in northern and eastern parts of the United States, but have been less frequent since 2000.11,15 Total seasonal snowfall has generally decreased in southern and some western areas, 16 increased in the northern Great Plains and Great Lakes region, 16,17 and not changed in other areas, such as the Sierra Nevada, although snow is melting earlier in the year and more precipitation is falling as rain versus snow.18 Very snowy winters have generally been decreasing in frequency in most regions over the last 10 to 20 years, although the Northeast has been seeing a normal number of such winters.19 Heavier - than - normal snowfalls recently observed in the Midwest and Northeast U.S. in some years, with little snow in other years, are consistent with indications of increased blocking (a large scale pressure pattern with little or no movement) of the wintertime circulation of the Northern Hemisphere.5 However, conclusions about trends in blocking have been found to depend on the method of analysis, 6 so the assessment and attribution of trends in blocking remains an active research area.

Bottom right: change in the average maximum number of consecutive days each year with less than 0.01 inches of precipitation.

To the north, in Montana, January is typically one of the drier months of the year with normal precipitation totals less than 1 in (25 mm).

Following a wet December, drier to much drier than normal conditions returned to California, Nevada, and Oregon this month, with precipitation less than 50 % of normal across large portions of these states.

The principal scientific objective is to make global SSS measurements over the ice - free oceans with 150 - km spatial resolution, and to achieve a measurement error less than 0.2 (PSS - 78 [practical salinity scale of 1978]-RRB- on a 30 - day time scale, taking into account all sensors and geophysical random errors and biases.Salinity is indeed a key indicator of the strength of the hydrologic cycle because it tracks the differences created by varying evaporation and precipitation, runoff, and ice processes.

With some exceptions, the tropics will likely receive less rain (orange) as the planet warms, while the polar regions will receive more precipitation (green).

Snowpack is melting earlier as winter and spring temperatures rise, and in most states an increasing percentage of winter precipitation is falling as rain, meaning there is often less snowpack to begin with.

Climatic variability in summer is projected to increase, with southern Europe experiencing more heat, less precipitation, and more frequent droughts — yet heavier rainstorms when it does rain.23 Northern Europe can expect more overall precipitation.21 Smog is also expected to rise — unless we reduce our use of fossil fuels.28, 29,30,31

The widespread trend of increasing heavy downpours is expected to continue, with precipitation becoming less frequent but more intense.13, 14,15,16 The patterns of the projected changes of precipitation do not contain the spatial details that characterize observed precipitation, especially in mountainous terrain, because the projections are averages from multiple models and because the effective resolution of global climate models is roughly 100 - 200 miles.

Overhead, matched - precipitation rotor systems are the best for irrigating green roofs, and they do a better job with less water than drip or sub irrigation methods.

According to Neilson, the latest models suggest that parts of the US are experiencing longer - term precipitation patterns, with less year - to - year variability but several wet years in a row followed by several years that are drier than normal.

Previous studies on the modification of precipitation trends by quantile mapping have focused on mean quantities, with less attention paid to extremes.

Evidence for widespread drought intensification is less clear and inherently difficult to confirm with available data because of the increase of time - integrated precipitation at most locations other than the subtropics.

One suggestion is that a warmer climate would have increased precipitation efficiency, causing more moisture to rain out, with less detrainment and a smaller area of upper - level cloud cover, limiting the positive longwave forcing (Lindzen et al. 2001).

By 2080 the prediction is that average temperatures could be 5 - 9 Fahrenheit warmer than they are now with more precipitation in the winter and sprint and less in summer.

A hot - dry climate is defined as region that receives less than 20 inches (50 cm) of annual precipitation with approximately 6,300 cooling degree days (50 degrees F basis)[3,500 cooling degree days (10 degrees C basis)-RSB- or greater and where the monthly average outdoor temperature remains above 45 degrees F (7 degrees C) throughout the year.

Those who like to check under the hood and kick the tires will find a tiny increase in precipitation over the 240 - year record, with an interesting smoothing of precipitation through the year - that is, there's been a little more rain in the drier December through May half and a little less in the soggier June through November half of the year.

«Within our lifetime, winters in Minnesota will become more like winters in Chicago — warmer with less snow and more precipitation coming as rain.»

It should also be possible to get less snow with the same amount of precipitation if e.g. the day - night variation increases, in that snow melts during the heat of the day and even if the cold of the night averages out the temperature, the added cold can not remake the lost snow.

In the lower left graph, consecutive dry days are defined as the annual maximum number of consecutive days with less than 0.01 inches of precipitation.
