- 摘要:
- 通过分析成都终端管制区的闪电活动情况,了解管制区闪电时空分布特征,提升雷暴天气预报服务能力。利用2015-2021年四川省ADTD闪电数据,统计分析成都终端管制区的闪电季节变化、月变化、日变化和空间分布特征。结果表明:成都终端管制区夏季闪电最多,集中在7月与8月,7月集中在管制区东部与东南部,8月集中在管制区南部与西南部,管制区东部闪电比西部多,持续时间更长; 闪电具有明显的日变化,夜间集中在后半夜,白天集中在午后; 天府机场闪电比双流机场多,天府机场主要集中在7月,且四周均有闪电,南部五边略少,双流机场集中在8月,西南部五边及三边较多; 天府机场比双流机场早一月出现雷暴天气,大多发生在3月,比双流机场晚一月结束雷暴天气,于10月结束。成都终端管制区闪电时空分布特征为流量、管制服务提供了一定的支持作用。
- Abstract:
- Through the analysis of the lightning activities in the Chengdu terminal control area, we can understand the temporal and spatial distribution characteristics of lightning in the control area and improve the service ability of thunderstorm weather forecast. Based on the ADTD lightning data of Sichuan Province from 2015 to 2021, the seasonal, monthly, diurnal and spatial distribution characteristics of lightning in Chengdu terminal control area are statistically analyzed. The results show that Chengdu terminal control area has the most lightning in summer, which is mostly concentrated in July and August, mainly in the east and southeast of the control area, and in the south and southwest of the control area in August. There are more lightning in the east of the control area than in the west, and the duration is longer. Lightning has obvious diurnal variation, which is more concentrated in the latter part of the night and in the afternoon during the day. Tianfu Airport has more lightning than Shuangliu Airport. Tianfu Airport is mainly concentrated in July, and there is less lightning on all sides in the south. Shuangliu Airport is mostly concentrated in August, and there are more five and three sides in the southwest. Tianfu Airport had thunderstorms in January earlier than Shuangliu Airport, mostly in March, and ended thunderstorms in January later than Shuangliu Airport, more than in October. The temporal and spatial distribution characteristics of lightning in Chengdu terminal control area provide some support for traffic flow and control services.
