Fig. 5: The distribution of EP flux divergence during the corresponding period at different latitudes (MERRA2 data).

EP flux divergence at (a) 17.5°N, (b) 12.5°N, (c) 7.5°N, and (d) 2.5°N, during 2015/16D and (e) 17.5°S, (f) 12.5°S, (g) 7.5°S, and (h) 2.5°S during 2019/20D. The red curve and shading represent climatology and ±1 standard deviation, respectively; the thin black lines represent EP flux divergence in 2015/16D and 2019/20D, respectively; the rectangular box marks the significantly enhanced negative forcing.
