| 摘 要： | 通过海南省16个气象台站2004～2005年自动站与人工并行观测气温资料的对比分析,根据相关标准对海南省自动站气温资料进行了评估.分析表明:海南省自动站与人工观测气温的偏差有日变化和季节差异.产生偏差原因有观测仪器的系统性偏差、观测仪器对气温变化响应的灵敏度、观测时间的差异、太阳辐射对观测仪器的影响等.建立了海口自动站与人工观测气温值之间的经验换算关系,为气候资料的前后连续性使用提供了订正的思路和方法. |

| Abstract: | Based on the parallel air temperature data of automatic sounding and manual observations at 16 weather stations in Hainan province from 2004 to 2005,a comparative analysis and evaluation is made on the validity.The results indicate that there are daily and seasonal differences between temperature observations recorded by AWS and conventional methods.The causes responsible for the differences are the systematic error,the sensitivity of two instruments to the environmental temperature change,the difference of the observation time and the effect of solar radiation.Because the long-range data were obtained from manual observation,the empirical conversion formula between the temperature records obtained by two instruments is provided for continuous use of the climate data after the changes in instruments. |
