高频地波雷达在辽宁省海上大风预警中的应用研究
Application of high-frequency ground wave radar in early warning of sea gale in Liaoning province
摘要
Abstract
Using the sea gale data detected by the high-frequency ground wave radar ( HFGWR ) in Dalian and Panjin cities and the wind data from the automatic meteorological stations along the coastal regions in Liaoning province,the retrieval results of HFGWR were evaluated based on analyzing the numbers of effective samples,ac-quisition rates,usability,average deviation,and standard deviation indices. The working situations of HFGWR were judged by the continuous detecting time and grading level of wind force. The results show that the overall perform-ance of HFGWR in Dalian is better than that in Panjin. The acquisition abilities to wind direction and wind speed data in Dalian are equal,and basically satisfy the needs of operation and application. The radar data acquisition rate in Panjin is mainly in agreement with that in Dalian,but the usability of these data is relatively low;there is a cer-tain gap from the real sea situation. Under a weak wind condition with wind speed less than 6 m·s-1,the wind fields detected by HFGWR in Dalian and Panjin both demonstrate a larger deviation from the real wind fields. When the wind speed is more than 6 m·s-1 ,the detecting ability of radar in Dalian is significantly improved and the detecting result generally reflects the actual wind change situation,while that in Panjin is not good enough. When the wind speed is more than 10 m·s-1 ,the detecting ability of radar in Dalian can be further improved.关键词
