风网格实况分析产品在黑龙江省的检验评估
Evaluation and validation of gridded wind field analysis products in Heilongjiang Province
摘要
Abstract
Using hourly ground observation data from 910 stations in Heilongjiang Province from 00:00 on 1 Janu-ary 2020 to 00:00 on 25 December 2024 as the benchmark,the national-level hourly 10 m wind gridded live analy-sis product with a 5km resolution was evaluated by utilizing tools such as the METEVA validation tool and bilinear interpolation methods.The results indicate that this product exhibits low mean error,absolute error,and root mean square error within Heilongjiang Province,maintaining good consistency.Overall,the product demonstrates good applicability in Heilongjiang Province.In terms of spatial error distribution,the accuracy is relatively lower in the western plains and southeastern mountainous regions,while in the other regions,the accuracy for errors within±2 m·s-1 exceeds 85％.This may be attributed to the complex topography in the southeastern mountains and the significant variations in underlying surface properties of the western plains.From the perspective of annual varia-tions,wind speed(wind force grade)generally exhibits negative deviations,particularly pronounced from April to May,while it performs relatively better in winter,with wind vectors displaying similar characteristics.The wind di-rection tests show better results in spring compared to summer.In terms of diurnal variations,the negative deviation of wind speed is larger during the daytime(08:00-18:00)and smaller at night.The smallest error is observed for winds of grade 0-1,while the negative deviation increase with winds for grade≥2,and the diurnal variation ampli-tude becomes significantly larger with winds for grade≥7.关键词
