Changes of Meiyu-Baiu features. (IMAGE) Science China Press Caption Figure 3. (a) 3D plots of three sub-indexes of deviation degree of misty rain (D2MR) in Nanjing during 1961–2023. The blue and green dots indicate years when D2MR was greater or less than ±0.2 standard deviations. The yellow rhombus indicates standard misty rain. Red, blue and black years represent hot–dry, heavy rain and traditional Meiyu years, respectively. (b) Variation in D2MR (bars) averaged in the Meiyu and Baiu regions from 1961 to 2023 and their quadratic trends (black curves). The linear trend of D2MR at sites (scatter) is also shown, and the grey and black crosses indicate that the trend is higher than the 90% and 95% significance level.
