Sentences with phrase «mo precipitation anomaly»

(A) Histogram of the frequency of occurrence of consecutive August — July 12 - mo periods in which the 12 - mo precipitation anomaly is less than — 0.5 SDs and the 12 - mo temperature anomaly is at least 0.5 SDs, in historical observations and the LENS large ensemble experiment.

This increase implies a transition to a permanent condition of ∼ 100 % risk that any negative — or extremely negative — 12 - mo precipitation anomaly is also extremely warm.

Not exact matches

(D) The unconditional probability of a — 1.5 SD seasonal precipitation anomaly (blue curve) and the conditional probability that a — 1.5 SD seasonal precipitation anomaly occurs in conjunction with a 1.5 SD seasonal temperature anomaly (red curve), for each of the four 3 - mo seasons.

(C) The probability that a negative precipitation anomaly and a positive temperature anomaly equal to or exceeding a given magnitude occur in the same 12 - mo period, for all possible 12 - mo periods (using a 12 - mo running mean; see Materials and Methods), for varying severity of anomalies.

All 20 August — July 12 - mo periods that exhibited a — 1.0 SD PMDI anomaly also exhibited a — 0.5 SD precipitation anomaly (Fig. 1B and 2E), suggesting that moderately low precipitation is prerequisite for a 1 - SD drought year.
