Blocking/RWB/Anticyclones - HAPPI

Blocking detected as masks form the daily 500-hPa geopotential (Scherrer et al. 2006). Anticyclones detected as masks from the daily 500-hPa geopotential (Wernli and Schwierz 2006). Rossby wave breaking (anticyclonic (_A) and cyclonic (_C) distinction) as grid points belonging to a wave breaking (Rivière 2009, Michel and Rivière 2011) detected from daily 250-hPa absolute vorticity. Blocking and RWB are detected for both the Present and +2C (Plus20-Future) experiments. Anticyclones are detected only for the Present (All-Hist) experiment. Data is available for the 5 HAPPI models: CAM4-2degree, CanAM4, ECHAM6.3-LR, MIROC5, and NorESM1-Happi.
