a Historical evolution of AMV indices investigated in this study for the period 1870–2017 calculated using the HadISST dataset40 (“Methods”). b, d, f, h, j Maps of averaged regression coefficients between the 10-years smoothed composite of the three AMV indices from panel a and CRU TS441 precipitation data for the period 1901–2017. Maps are, showing Annual, December–January–February (DJF), March–April–May (MAM), June–July–August (JJA), and September–October–November (SON) regression coefficients, respectively. c, e, g, i, k Maps of regression coefficients between the composite of the three AMV indices from panel a and CRU TS441 surface temperature data for the period 1901–2017. Maps are respectively showing Annual, DJF, MAM, JJA, and SON regression coefficients, respectively. For all maps, white grid points indicate that regression coefficients are not significantly different than 0 at the 90% confidence level, using a two-tailed student test with corrected degrees of freedom45 (“Methods”).
