根据浙江省建站始到2011年70个地面观测站的雷暴日资料、浙江省电力部门闪电定位系统的2005—2011年地闪数据和电网雷害资料，分析研究了浙江省雷电的时空分布特征及影响因素。研究结果表明：浙江省雷电主要集中在3—9月，多发生在15—16时段。全省雷暴日分布呈现山区比平原地区多，内陆比沿海多的特点。地闪密度呈现明显的地域性差异，地闪高密度区表现为两大片、若干点的分布。负闪占总地闪的百分率为94.91%。正、负闪电强度主要集中在0~50 kA。地闪高密度区的分布，与气候、地形、地貌、地面大型水体和城市热岛效应有着密切关系。

Based on the recorded data of thunderstorm days from 70 surface observation stations in Zhejiang province ever since their building up to 2011 and the cloud-to-ground lightning data recorded by lightning detection and location system of Zhejiang power bureau and the record of damages caused by thunders from 2005 to 2011, the temporal-spatial distribution characteristics of thunder and lightning in Zhejiang province and influencing factors are analyzed and researched. Research results show that the lightning phenomena mainly appear from March to September and mostly happen in the time period from 15:00 to 16:00. The distribution of thunderstorm days present such a feature that the amount of thunderstorm days appear in mountain area is more than that in plain area, and that in inland area is more than that in coastal areas. There is obvious regional difference in the density distribution of cloud-to-ground lightning: it appears as the distribution in two large areas and several points. The percentage of negative cloud-to-ground lightning in total cloud-to-ground lightning is 94.91%. The positive and negative lightning intensities mainly appear in the range from 0 kA to 50 kA. The distribution of areas with high density of cloud-to-ground lightning in Zhejiang province is bound up with whether, landform, topographic feature, surface large-scale water mass and urban heat island effect.
