Sentences with phrase «greatest precipitation anomalies»

Not exact matches

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).

Over ocean stretches with a positive SST anomaly air convection is higher (as the temperature difference between the warm sea surface and the cool air higher up in the troposphere is greater), so a higher likelihood for the formation of depressions exists and more precipitation is to be expected.

The Bottom panels (C and D) show the unconditional probability (across the ensemble) that the annual precipitation anomaly is less than — 0.5 SDs, and the conditional probability that both the annual precipitation anomaly is less than — 0.5 SDs and the temperature anomaly is greater than 0.

But given what is known, he said «there is every reason to believe that the trend toward greater variability, larger anomalies, is true for precipitation as well as temperature.»

We find that although there has not been a substantial change in the probability of either negative or moderately negative precipitation anomalies in recent decades, the occurrence of drought years has been greater in the past two decades than in the preceding century.
