Figure 4: Vectors of the vertically integrated moisture transports for (A) high NAO index winters and (B) normal or low NAO index winters. Evaporation minus precipitation computed from the atmospheric moisture budget for high minus normal or low NAO index winters is shown in (C). The contour interval of the magnitudes is 50 kg/(m s) in (A) and (B). The contour interval in (C) is 0.5 mm/day, and the stippling indicates values significantly different from zero at the 5% level using a t-test.
