Specific humidity (kg kg−1) cluster 3 RI cross section composite 1000–850 hPa (panel (a)) and non-RI cross section composite (panel (b)) and the resulting differences in the permutation test of the fields for 1000–850 hPa (panel (c): shaded areas are significant at or less). The dry region over the storm center was apparent for 3 RI clusters in cross section composite fields, while the value field revealed inflow region as statistically significant.
