  1. Palline 2 Tmax in ON

  2. The new sensitivity experiments Superimposed anomalies are turned on from June to February, following the idealized seasonal cycle The exception is the tropical Atlantic anomaly, turned on from October to June, following the idealized lag Niño-Atlantic Niño mode

  3. Tmax SD – ON – Sensitivity to the SST forcing • In all the experiments, Tmax variance maximizes in N Patagonia and along the eastern SA • Pacific and Atlantic forcings are associated with ↑ variance in Amazonas. • Indian forcing is related with ↓ variance at around 20°S

  4. Tmax – ON – Sensitivity to the Pacific Dateline SST forcing • The ↑ variance in Amazonia is related with • Large ↑ of the threshold of the P75 (45% of days falling in the 4th quartile) • Moderate ↑ of the threshold of the P25 (no more than 15% of days falling in the 1st quartile) • ↑ in the Tmax mean field Tmax Mean Tmax P75 Tmax P25 NoD [%] with Tmax in the 4th quartile NoD [%] with Tmax in the 1st quartile • The ↑ in the Tmax mean field in LPB and Central-North Argentina is related with • ↑ of the threshold of the P75 (35% of days falling in the 4th quartile) • ↑ of the threshold of the P25 (15% of days falling in the 1st quartile) • Few changes in variance

  5. Tmax – ON – Sensitivity to the basin forcings

  6. Supply and demand limitation of ET Ro(ET,T2m), with negative correlations (blue) . Estimation based on annual mean “observed” values ET is limited by atmospheric demand Ro(ET, PP) with positive correlations indicating coupling ET is limited by soil moisture supply Classifying the regions with either T (demand limitation) or P (supply limitation) Jung et al., 2010
