September Arctic SIE anomalies with (A) inverted annual mean HTATL, (B) inverted annual mean HTPAC, (C) inverted spring AD, and (D) reconstructed September Arctic SIE anomalies. All time series are 30-y LF and normalized by corresponding SDs [σ(SIE) = 0.22 × 106 km2, σ(SIER) = 0.17 × 106 km2, σ(HTATL) = 8.5 TW, σ(HTPAC) = 0.35 TW, σ(AD) = 8.0 hPa].
