Sentences with phrase «precipitation year»

The state has hot summers and mild winters, as well as a great deal of precipitation year round.

The fact that the occurrence of warm and moderately dry years approaches that of moderately dry years in the last decades of the Historical experiment (Fig. 3 B and C) and that 91 % of negative precipitation years in 1995 — 2014 co-occurred with warm anomalies (Fig. 1B) suggests possible emergence of a regime in which nearly all dry years co-occur with warm conditions.

«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.

However, the Historical experiment exhibits greater probability of a — 0.5 SD precipitation anomaly co-occurring with a positive temperature anomaly (0.001 significance level)(Fig. 3D), suggesting that human forcing has caused the observed increase in probability that moderately dry precipitation years are also warm.

Humid Continental Hot, humid summers & cold winters with moderate precipitation year round.

For example, of the 63 negative precipitation years during 1896 — 2014, 15 of the 32 warm — dry years (47 %) produced 1 - SD drought, compared with only 5 of the 31 cool — dry years (16 %)(Fig. 2A).

The size of the Gulf of Mexico dead zone fluctuates annually, but increased precipitation this year amplified runoff.

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.

This detectable increase in extremely low - precipitation years adds to the effect of rising temperatures and contributes to the increasing occurrence of extremely warm — dry 12 - mo periods during the 21st century.

Because some species respond predictably by producing narrower annual rings when rainfall declines, the researchers were able to plot precipitation year by year from the 1500s on.

In ponderosa pine ecosystems, soil texture is an important factor in forest water stress during lower precipitation years and post-disturbance regeneration (Scianna [2011]-RRB-.

Winnipeg has 2.6 doctors for every 1,000 people, clean air and just 514 mm of precipitation each year.

Empirical studies of forests across Alaska show that North America's white spruce require at least 280 millimeters (11 inches) of precipitation each year, a number that rises if mean summer temperatures are higher than 15.5 degrees Celsius (roughly 60 degrees Fahrenheit).

Deserts are arid regions, generally receiving less than 25 centimeters (10 inches) of precipitation a year, or regions where the potential evaporation rate is significantly greater than the precipitation.

has decreased in winter, but no significant change in annual mean precipitation potentially because of very slight increases in spring and fall precipitation; precipitation is projected to increase across Montana, primarily in spring; slight decrease in summer precipitation; variability of precipitation year - to - year projected to increase

Antarctica is technically a desert — with an average 166 mm of precipitation a year — but snow that falls tends to stay, and becomes packed ever tighter with the decades.

Rather, the observed doubling of the occurrence of 1 - SD drought years has coincided with a doubling of the frequency with which a negative precipitation year produces a 1 - SD drought, with 55 % of negative precipitation years in 1995 — 2014 co-occurring with a — 1.0 SD PMDI anomaly, compared with 27 % in 1896 — 1994 (Fig. 1 A and B).

These increases in drought risk have occurred despite a lack of substantial change in the occurrence of low or moderately low precipitation years (Figs. 1B and 2 A and B).

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.

In addition, we find that human emissions have increased the probability that low - precipitation years are also warm, suggesting that anthropogenic warming is increasing the probability of the co-occurring warm — dry conditions that have created the current California drought.

Antarctica, for example, is the driest continent on earth, getting less than 4 in / 10 cm of precipitation a year.

The Alberta Crop Report advises that seeding as of May 31, 2012 is 94 % completed in the province, with good germination and precipitation the year is off to a promising start.
