Precipitation (shades, unit: mm day−1) and geopotential height (contour, unit: gpm) fields in three EC cases with different horizontal scale at a 1800 UTC on July 4, 2013, b 0000 UTC on June 26, 2005 and c 0600 UTC on July 25, 2014. The black dots show the cyclone center point. The yellow dots show the location of vqmax. The distribution of vertically integrated water vapor flux (black vector, unit: g m−1 s−1) and its divergence (shades, unit: g m−2 s−1) and vertical motion (white contours denote the values of − 0.5, − 1 Pa s−1) (d–f). The black line in d is a Meiyu front adapted from JMA (https://www.data.jma.go.jp/fcd/yoho/data/hibiten/2013/1307.pdf)
