Fig. 5 Morlet wavelet analysis of the number of days with the Yunnan-Guizhou quasi-stationary front in winter (a) and December (b), January (c) and February (d) from 1991 to 2023 (The shaded areas indicate that results are statistically significant at the α=0.1 level. The yellow dashed lines denote the regions affected by the edge effects and the red line represents edge effect line in the wavelet analysis)
