Linear regression coefficients of I_NP in summer on the SLP field (a) unit: hPa, T₈₅₀ (b) unit: °C, H₅₀₀ (c) unit: gpm, UV₈₅₀ (d) unit: m/s, and U₂₀₀ (e) unit: m/s in winter. All values are multiplied by −1, and shaded areas represent statistical significance at the 90% confidence level using Student’s t-test.
