These findings from University of Melbourne Scientists at the ARC Centre of Excellence for Climate System Science, reported in Nature Climate Change, are the result of research looking at how Australian extremes in heat, drought, precipitation and ocean warming will change in a world 1.5 °C and 2 °C warmer than pre-industrial conditions.

That shift caused warmer temperatures in the north - west US, fewer storms in the south - east, and reduced precipitation in the west — conditions that persisted for about a decade.

It caused warmer temperatures in the north - west US, fewer storms in the south - east, and reduced precipitation in the west — conditions that persisted for about a decade.

Daniel Swain and colleagues model how the frequency of these rapid, year - to - year transitions from extreme dry to wet conditions — which they dub «precipitation whiplash events» — may change in California's future as a consequence of man - made warming.

There is also more intense rainfall in the warm tropics than the cooler extra-tropics, and summer precipitation is often more intense than in winter due to different physical conditions.

This dependency to physical conditions is evident from how the temperature and precipitation vary from place to place: typically warmer at low latitudes and cooler at higher altitudes; more rain near the coast and less in the interior.

Alaska's warm spell was caused by high pressure conditions in the Pacific Ocean, which pushed the warm air and precipitation that usually ends up in California this time of year into the 49th state.

«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 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.

«You're also correct in pointing out that snow accumulating in the East Antarctic interior is increasing, presumably due to increased precipitation caused by more humid conditions caused by warming air.»

However, studies that stratify winters into La Niña, neutral, and El Niño phases have found that precipitation extremes in neutral / La Niña winters respond differently than in El Niño winters, whereas studies that stratify ENSO data into cold / warm conditions have not found evidence for a coherent nonlinear response.

A 2015 study found that warm conditions induced by human - caused global warming have already increased the risk of severe drought in California, even in the absence of trends in precipitation.

In 1965 British climatologist Hubert Horace Lamb examined historical records of harvests and precipitation, along with early ice - core and tree - ring data, and concluded that the MWP was probably 1 — 2 °C (1.8 — 3.6 °F) warmer than early 20th - century conditions in EuropIn 1965 British climatologist Hubert Horace Lamb examined historical records of harvests and precipitation, along with early ice - core and tree - ring data, and concluded that the MWP was probably 1 — 2 °C (1.8 — 3.6 °F) warmer than early 20th - century conditions in Europin Europe.

As the climate changes in response to global warming, longer and more severe droughts are projected for the western US The resulting dry conditions will increase the pressure on groundwater supplies as more is pumped to meet demand even as less precipitation falls to replenish it.

Warming is linked to increases in precipitation extremes partly because of the physical effect of warming on atmospheric condWarming is linked to increases in precipitation extremes partly because of the physical effect of warming on atmospheric condwarming on atmospheric conditions.

Over northern continents in winter, however, more precipitation is associated with higher temperatures, as the water holding capacity of the atmosphere increases in the warmer conditions.

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, continued global warming is likely to cause a transition to a regime in which essentially every seasonal, annual, and multiannual precipitation deficit co-occurs with historically warm conditionIn addition, continued global warming is likely to cause a transition to a regime in which essentially every seasonal, annual, and multiannual precipitation deficit co-occurs with historically warm conditionin which essentially every seasonal, annual, and multiannual precipitation deficit co-occurs with historically warm conditions.

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.

Our results suggest that anthropogenic warming has increased the probability of the co-occurring temperature and precipitation conditions that have historically led to drought in California.

Taken together, the observed record from California suggests that (i) precipitation deficits are more likely to yield 1 - SD PMDI droughts if they occur when conditions are warm and (ii) the occurrence of 1 - SD PMDI droughts, the probability of precipitation deficits producing 1 - SD PMDI droughts, and the probability of precipitation deficits co-occurring with warm conditions have all been greater in the past two decades than in the preceding century.

Indeed, our results show that even in the absence of trends in mean precipitation — or trends in the occurrence of extremely low - precipitation events — the risk of severe drought in California has already increased due to extremely warm conditions induced by anthropogenic global warming.

Wang and Schubert (2014) find that the North Pacific SST warm anomalies during early 2013 created a «predilection» for dry conditions during the second half of the 2013 - 2013 «rainy season» in California, and Funk et al. (2014) also report that the observed Pacific SST anomalies during 2013 - 2014 contributed to the extremely low precipitation that was observed during 2013 - 2014.

In a warmer world, air holds more water vapor, so when cloud conditions are right for that vapor to form droplets, more precipitation falls.
