However, long - term precipitation deficits and drought conditions continued to plague most of California by the end of the year.

From the perspective of soil moisture, the ongoing drought is the worst in at least the last 1,200 years, the study found, adding that the high temperatures in the past few years may have aggravated the precipitation deficits by nearly 40 %.

In particular, a stronger southern center - of - action of the NAO (i.e., a stronger high pressure anomaly) and a northward shift of the SLP dipole nodal line is associated with greater precipitation deficits over southern and central Europe; and a southward shift of the nodal line accompanied by stronger anomalous westerly flow across northern Europe and Russia favors enhanced precipitation and warming in these regions (Fig. 4).

temperature could have exacerbated the 2014 drought by approximately 36 %... These observations from the paleoclimate record suggest that high temperatures have combined with the low but not yet exceptional precipitation deficits to create the worst short - term drought of the last millennium for the state of California... Future severe droughts are expected to be in part driven by anthropogenic influences and temperatures outside the range of the last millennium.

There is little evidence for a human influence on precipitation deficits, but a lot of evidence for a human fingerprint on surface soil moisture deficits — starting with increased evapotranspiration caused by higher temperatures.

[4] Thanks to a strong El Niño that brought near average precipitation to the northern California, the statewide April 1 snowpack measurement in 2016 showed state water resources at 87 percent of the long - term average; however, the snowpack was not sufficient to undo water deficits caused by years of drought.

The proximal cause of the precipitation deficits was the recurring poleward deflection of the cool - season storm track by a region of persistently high atmospheric pressure, which steered Pacific storms away from California over consecutive seasons (8 ⇓ ⇓ — 11).

Although precipitation deficits are a prerequisite for the moisture deficits that constitute «drought» (by any definition)(15), elevated temperatures can greatly amplify evaporative demand, thereby increasing overall drought intensity and impact (16, 17).

They foresee a period characterised by what they politely called «recurring precipitation deficits»: in other words, sustained and potentially catastrophic drought.
