Sentences with phrase «more precipitation this year»

El Niño will create a mixed bag in terms of precipitation too, with increased odds that Southern California will see more precipitation this year — though it's too early to know if that will come in the form of snow — while the Pacific Northwest is likely to be drier and could see its drought deepen.

Not exact matches

Northern California, where I live, definitely tends to get more precipitation this time of year than it does the rest of the year.

Apparently, winter precipitation was more important than summer temperature for annual glacier balance when only considering subsets of years with high NAO index and negative AMO index.

A decrease in precipitation frequency translates into even more year - to - year variability in fresh water resources for the Southwest.

For more than 20 years, scientists have tossed around the idea that bacteria play a role in precipitation.

The drought in California has been building for more than four years, as winter precipitation deficits slowed streams to a trickle and sent reservoir levels dipping, while unusually warm temperatures increased water demand.

A Climate Central analysis of 65 years of winter precipitation data from more than 2,000 weather stations in 42 states, found a decrease in the percent of precipitation falling as snow in winter months for every region of the country.

And even in wet years, warmer temperatures could mean that more precipitation falls as rain, not snow, setting up the possibility that many more years will see an April 1 with very little snow.

And California had a near average wet season, which sounds good except for the fact that the state needed a lot more precipitation than it got to kick its four - year drought to the curb.

In locations that are accustomed to getting snow during the winter, the total amount of snow each year is already decreasing as the planet warms from increasing greenhouse gases; the percentage of precipitation falling as snow is on the decline, with more of it falling as rain.

Although not the driest month of the year, September is usually much more arid, with average total precipitation of 1.61 inches.

However, higher temperatures do cause an increased chance of heavy precipitation events, and it is likely that the flooding in some of this year's U.S. flooding disasters were significantly enhanced by the presence of more water vapor in the air due to global warming.

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

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.

But also non-usuals like earthquackes (clustering in the upgoing flank of the solar cycle, as is the case now) and even the number of wars (probably spurious, but continuous bad weather, as in our «summer» now, influences one's mood, thus more fights, etc.).

If more heat causes more precip, then, since the climate has definitely warmed since the 1950's — a 60 plus year period, we should definitely see more precipitation, shouldn't we?

«Warming in California has made it more probable that when a low precipitation year occurs, it occurs in warm conditions and is more likely to produce severe drought,» said lead study author Noah Diffenbaugh, an associate professor in the School of Earth Sciences at Stanford.

The first kind of precipitation whiplash is from year to year, meaning that we'll see more extraordinarily dry years followed by incredibly wet years — in the way California's five - year drought ended in 2017 in one of the wettest winters on record.

And current climate change trends could easily increase the chance of bad flooding — there's more water vapor in the atmosphere now (ready to condense into storm clouds and precipitation), for example, than there was 70 years ago.

The researchers looked at historical temperature and precipitation records to find out whether drought conditions were more likely to hit during warm or cold years in the past.

Precipitation on the continent became more common, from around 14,700 years ago until 3,000 years before the Common Era.

Many climatic parameters (ground and ocean surface temperatures, pressure, atmospheric precipitation, etc.) have temporal variations with characteristic periods from several to several tens of years or more.

In addition, climate change is very likely to lead to more frequent extreme heat events and daily precipitation extremes over most areas of North America, more frequent low snow years, and shifts towards earlier snowmelt runoff over much of the western US and Canada (high confidence).

While the years with warm and wet weather extremes have also become more common in the state, increased temperatures accompanying the precipitation tend to lead to quicker evaporation, Diffenbaugh said.

More extreme precipitation events (with 3 - hour duration) so intense than in the past they would be exceeded on average only once every 10 years are projected to occur on average three times as often in future in Metro Vancouver and about three and a half times as often in future in CRD.

In the Northeast US extreme precipitation has increased by more than 70 % in the last 50 years and is projected to continue to increase.

The basin could experience more precipitation with climate change, or bigger swings between wet and dry years or possibly even longer, more severe «megadroughts.»

Combined with diminished precipitation, high temperatures in California are causing soils and vegetation to lose moisture earlier in the spring and stay dry later in the fall, meaning the landscape is flammable for more of the year.

Our analyses show that California has historically been more likely to experience drought if precipitation deficits co-occur with warm conditions and that such confluences have increased in recent decades, leading to increases in the fraction of low - precipitation years that yield drought.

The probability that a negative precipitation anomaly co-occurs with a positive temperature anomaly has increased recently, with warm — dry years occurring more than twice as often in the past two decades (91 %) as in the preceding century (42 %)(Fig. 1B).

Very heavy precipitation events, defined as the heaviest one percent of storms, now drop 67 percent more precipitation in the Northeast, 31 percent more in the Midwest and 15 percent more in the Great Plains than they did 50 years ago.

More generally, regional variations of temperature and precipitation modify the fluxes from year to year, for instance during El Niño events.

A hot - humid climate is defined as a region that receives more 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.

Our approach in Swain et al. (2014) doesn't allow us to determine whether the amplitude of the flow pattern itself (i.e. its «ridgey - ness») is increasing, nor whether years with extremely low precipitation have become more common.

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.

Coincident with the increasing amplitude and variability of the «dipole» pattern (Wang et al. 2014), big swings in California precipitation (i.e. the occurrence of both very wet years and very dry years) are expected to become more common over the course of the 21st century (Wang et al. 2014, Funk et al. 2014).
