TNSmart Lightning Nowcast Dataset
收藏资源简介：
The Lightning Nowcast Dataset offers a comprehensive overview of the likelihood of lightning occurrences within the next 30-40 minutes at the district level, tailored for meteorologists, emergency response teams, and the general populace for immediate hazard preparedness. It distinguishes between cloud-to-cloud and cloud-to-ground lightning through unique icons, where the icon colors indicate the recency of lightning (ranging from 0-30 minutes) and the colors on the block underneath signify the intensity of cloud-to-ground flashes (No, Low, Moderate, High). Additionally, the dataset provides lightning polygons to depict areas affected by varying intensities of lightning activity, classified into three levels (Low - Level 1, Medium - Level 2, High - Level 3 (DTA)), and lightning cell tracks to measure storm activity levels in flashes per minute, categorized into ranges from 0 to over 50. An advisory section offers insights into significant weather activities, like the example mentioning no notable lightning or thunderstorm activity in Tamil Nadu, making this dataset a vital tool for weather forecasting and emergency preparedness, aiding in the mitigation of lightning-related risks. The lightning dashboard also contains data on recent events and 48 hour forecasts based on datasets by IMD and National Centre for Medium Range Weather Forecasting
闪电临近预报数据集（Lightning Nowcast Dataset）提供了行政区级别下未来30至40分钟内闪电发生概率的全面概览，专为气象工作者、应急响应团队及普通民众开展即时灾害防范工作定制。该数据集通过专属图标区分云闪（云-云闪电）与地闪（云-地闪电）：图标颜色代表闪电发生的时效性（范围为0至30分钟），下方色块的颜色则表示地闪强度等级，分为无、低、中、高四个级别。此外，数据集还提供闪电多边形数据，用于刻画受不同强度闪电活动影响的区域，强度分为三级（弱-1级、中-2级、强-3级（DTA））；同时提供闪电单体追踪数据，以每分钟闪击次数衡量风暴活动水平，分类区间覆盖0至50次以上。数据集附带的预警板块可提供重大天气活动相关研判信息，例如示例提及泰米尔纳德邦境内无显著闪电或雷暴活动，使其成为天气预报与应急筹备的关键工具，助力减轻闪电相关灾害风险。该闪电预警仪表板还包含由印度气象局（IMD）及国家中期天气预报中心（National Centre for Medium Range Weather Forecasting）提供的近期事件数据与48小时预报信息。
