摘要:
基于2013-2022年梧州市153个加密自动站的逐小时降水资料,分析梧州市短时强降水时空分布特征。结果表明:(1)梧州市短时强降水年发生频次呈现"W"式波动变化,主要出现在3-9月。月际分布总体呈现"双峰"结构特征,主峰出现在5-6月,次峰出现在8月。(2)短时强降水发生频次有明显的日变化特征,高频发时段出现在13:00-20:00。(3)梧州市短时强降水频次前汛期要多于后汛期,且空间分布有较大的差异性,南北多中部少,主要分布在大瑶山、大桂山以及云开大山附近,可能受地形影响有关。
Abstract:
Based on the hourly precipitation data from 153 encrypted automatic stations in Wuzhou City from 2013 to 2022, the spatial and temporal distribution characteristics of short-term heavy precipitation in Wuzhou City are analyzed. The results show that:(1)The annual frequency of short-duration heavy precipitation in Wuzhou City shows "W"-type fluctuation, mainly in March-September. The inter-monthly distribution is characterized by a "double-peak" structure, with the main peak occurring in May-June and the second peak in August.(2)The frequency of short-term heavy precipitation has obvious diurnal characteristics, with high frequency occurring from 13:00 to 20:00.(3)The frequency of short-term heavy precipitation in Wuzhou City is more frequent in the first flood season than in the second flood season, and the spatial distribution has a greater variability, with more in the south and north and less in the central part of the city, and it is mainly distributed in the vicinity of the Dayaoshan Mountain, Daguishan Mountain, and Yunkai Mountain, which is likely to be affected by the influence of the terrain.
