| description | Lightning and precipitation data were used to analyze the lightning and rainfall characteristics during "6·27" super rainstorm of Hubei Province in 2020. The results showed that lightning in this rainfall event is dominated by negative lightning, although proportion of positive lightning was higher than statistical value. Positive lightning had active phases at the beginning and end of heavy rainfall, while negative lightning became active when heavy rainfall emerged. Lightning concentrated regions are located on the southern area of 850 hPa warm shear which was the exit region of low-level jet. High frequency regions were areas between the end of 700 hPa and 850 hPa warm shear line or the left of low and ultra-low jet flow. The area of lightning and rainfall had obvious corresponding relation. That is, high frequency regions and areas with rainfall higher than 50 mm were almost coincided. Lightning concentrated regions were almost coincident with areas with rainfall higher than 40 mm·h-1. Lightning concentrated regions located at the center and leading edge of intense precipitation, negative lightning corresponded with relatively strong rainfall, and proportion of positive lightning increased on the edge of storms. Lightning frequency had a consistent trend with rainfall, and the peak of lightning might be either ahead or behind rainfall maxima in different storms. |
