摘要
为探讨NCEP/NCAR再分析温度网格资料在农业气象研究中的应用价值,以北京、南京、广州、昆明、郑州和三亚6个气象台站的实测地面气象资料为依据,证明了NCEP/NCAR再分析温度网格资料的可靠性。进一步用Cressman插值、双线性二次插值、抛物线二次插值以及先抛物线插值后线性插值等4种插值方法,用NCEP/NCAR再分析温度网格资料对上述6站的地面日平均气温进行了插值计算,并对不同插值方法的结果作了比较。结果表明,站点纬度较高时(30°N以北),应用双线性二次内插法插值效果较好,精度略低;站点纬度较低时(30°N以南),应用Cressman插值法插值效果好,精度也高。这可能是较高纬度缺测资料较多造成的。利用NCEP/NCAR再分析网格温度插值资料分析两系法杂交水稻在泰国的制种气候适应性证明该资料在农业气象研究中是可以应用的。
In order to explore the applied value of the NCEP/NCAR reanalysis temperature data in studies on agricultural meteorology and environmental meteorology,this paper demonstrates the reliablity of the NCEP/NCAR data in context of the real ground surface observational data in Beijing,Nanjing,Guangzhou,Zhengzhou,Kunming,as well as Sanya.Using four kinds of interpolation methods,namely Cressman interpolation,parabolic interpolation,linear interpolation,parabolic and linear interpolation,the daily surface average temperatures of the NCEP/NCAR data are interpolated to the above six stations,and results from different interpolational methods are compared.Results show,for stations on a higher latitude north of 30°N,the bilinear interpolation method is better,but its accuracy is slightly lower.And for stations on a lower latitude south of 30°N,the Cressman interpolation is better,and more accurate.This may be related to that there are more missing data in the higher latitude.The paper proves that applying the interpolated temperature data to the analysis of the climatic adaptation of the seed production of two-line hybrid rice Pei'ai 64S in Tailand is feasible.
