天津市滨海新区塘沽地域雷暴日数变化规律及特征分析

Analysis of Thunderstorm Days and Their Variation Characteristics in Tanggu Area of Binhai New Area

雷电放电会在很短的时间内释放出庞大的能量,其高电流和高电压具备极强的破坏性和致命性。伴随着电子信息技术的广泛应用,雷电灾害的风险水平愈来愈高,对国民经济造成的风险和社会影响也日趋严重。天津滨海新区塘沽地处渤海湾,其特殊的地理位置和环境条件,导致夏季常常遭到雷暴的影响。基于塘沽地域近50年(1964-2013年)雷暴日数的相关资料,采用35 a(1964-1998年)和近15a(1999-2013年)相应的雷暴日数据进行对比分析,旨在通过分析总结它的发生规律,在该地域实施有效的雷电防护措施、雷暴监测预警以及防灾减灾工作。

Lightning discharge will release huge energy in a very short time, and the resulting large current and high voltage have extremely strong destructive power and lethality. With the wide application of electronic information technology, the risk level of lighting disaster becomes higher and higher, and the risk and social impact on national economy become increasingly serious. Tanggu is located in the Bohai Bay. Due to its unique geographical location and environment, it is often affected by thunderstorms in summer. Based on the relevant data of thunderstorm days in the Tanggu area in the past 50 years(1964 to 2013), the corresponding thunderstorm day data of 35 years(1964 to 1998) and nearly 15 years(1999 to 2013) are used for contrastive analysis. The purpose is to understand its occurrence law through analysis, which is of great significance to the implementation of effective lightning protection measures, thunderstorm monitoring and early warning, and disaster prevention and mitigation in this area.
