Fig. 2

Time series of the interannual monthly mean TP SPV (PVU) anomalies (relative to the mean over the 1979–2022 period) where the topography is above 3 km for June, July, and August. The purple line denotes the regional mean of TP SPV where the standard deviation of interannual TP SPV is above 5 in June. The red circles denote the typical years of 1983, 1995, and 2022 (the TP SPV in June was especially weak or strong).
