Fig. 1: Annual AR frequency and trends.
From: Intense atmospheric rivers can weaken ice shelf stability at the Antarctic Peninsula

Frequency of AR landfalls on the Antarctica Peninsula for a, b December–March and c, d yearly according to the vIVT and IWV AR detections schemes when applied to MERRA-2 and ERA-5 reanalysis. b, d represent the AR frequency when all AR landfalls with a maximum IVT below 400 kg m−1 s−1 are removed from the record. The year in a and b refers to the austral summer of December, January, February, March (i.e., the austral summer of 1988-1989 is referenced as 1989 in the plots). An AR landfall is counted if an AR shape touches the region highlighted in e which also shows the locations of the Larsen A and B embayments, Larsen C ice shelf, and Wilkins ice shelf.
