高质量西太平洋台风路径气象数据集
收藏资源简介:
本数据集依托中科天机全球-区域一体化数值天气模式,提供海平面气压、十米风场等高分辨率台风关键要素,并结合多模式多成员超级集合模拟与历史台风数据的人工智能算法订正技术,对模式误差进行动态校正。中科天机台风数据对已命名热带气旋启动台风模拟数据服务,持续至该热带气旋停止编报。数据文件包含台风中心纬度、台风中心经度、台风中心海平面气压、台风最大十米风速、台风移动方向、台风移动速度、最大风速风圈半径等要素模拟。数据更新频率为每日 2 次,最长模拟时效可达 240 小时,模拟时间步长为 6 小时。
Built upon the CAS Tianji Global-Regional Integrated Numerical Weather Prediction (NWP) Model, this dataset provides high-resolution key typhoon-related parameters including sea level pressure, 10-meter wind field, etc. It dynamically corrects model errors via artificial intelligence-based algorithmic correction techniques that integrate multi-model and multi-member superensemble simulations and historical typhoon datasets. The CAS Tianji typhoon dataset launches typhoon simulation data services for named tropical cyclones, and the service remains active until the tropical cyclone ceases official reporting. The data files include simulated values of multiple core typhoon parameters: the latitude and longitude of the typhoon center, sea level pressure at the typhoon center, maximum 10-meter sustained wind speed, typhoon moving direction, typhoon moving speed, and radius of maximum wind (RMW), among others. The dataset is updated twice daily, with a maximum simulation lead time of up to 240 hours and a simulation time step of 6 hours.
