摘要
基于世界气象组织(WMO)滚动需求原则,利用观测系统能力分析和审查工具(OSCAR)需求指标,结合广西2024年地面气象观测站网数据,对站点布局、观测能力和要素分辨率等进行系统评估。结果表明,广西气象观测站网存在站点类型分布不均,多要素站点不足,常规气象要素水平分辨率与“突破值”差距明显,交通、雷电、农业等专业领域观测站点稀少,设备类型与功能不足等问题。建议从增加多要素站点比例、填补观测空白区、缩小常规气象要素分辨率差距、优化网格覆盖率、建设专业气象观测网等方面优化广西气象观测站网布局。
Based on the World Meteorological Organization(WMO)rolling demand principle,using the Observation System Capability Analysis and Review Tool(OSCAR)demand indicators,a systematic assessment was conducted on the station layout,observation capabilities,and element resolution in combination with the ground meteorological observation station network data in Guangxi in 2024.The results indicate that the Guangxi meteorological observation station network faces issues like uneven distribution of station types and insufficient multi-element stations,obvious gap between the horizontal resolution of meteorological elements and the“breakthrough value”,scarcity of observation stations in specialized fields such as transportation,lightning,agriculture,and insufficient types and functions of equipment,etc.It is suggested to optimize the layout of meteorological observation station network in Guangxi in terms of increasing the proportion of multi-factor stations,filling the observation gap area,narrowing the gap of resolution of regular meteorological elements,optimizing the coverage of grids,and constructing specialized meteorological observation networks.
