图6 1991—2020年重庆西部(a、b、c)、中部(d、e、f)、东北部(g、h、i)、东南部(j、k、l)水稻苗期(a、d、g、j)、营养生长期(b、e、h、k)和生殖生长期(c、f、i、l)连阴雨发生频次与500 hPa位势高度场距平回归分析(单位:gpm) (黑色线为500 hPa位势高度场,红色线为588 dagpm线,黑色打点为通过α=0.05显著性检验区域) |
Fig.6 The geopotential height anomaly at 500 hPa regressed with the frequency of continuous rain occurrence at seedling stage (a, d, g, j), vegetative growth stage (b, e, h, k) and reproductive growth stage (c, f, i, l) of rice in the western (a, b, c), central (d, e, f), northeastern (g, h, i) and southeastern (j, k, l) of Chongqing from 1991 to 2020 (Unit: gpm) (The black lines indicate the 500 hPa potential height field, the red lines indicate the 588 dagpm line, and the black dot is the area that passed the significance test at α= 0.05) |
