建阳市气象自动观测与人工观测资料对比分析

Data comparisons between automatic and manual observation in Jianyang

通过对建阳市2004-2005年自动观测和人工观测资料的对比分析,发现自动观测资料中最高温度明显高于人工观测值;此外自动站观测的风速较人工站的大;极端相对湿度较人工站观测的明显偏小;降水量、气压差值不大。自动站与人工站观测数据的差异,主要是由于仪器的原理不同,观测采样方式与算法不同造成的,自动站观测结果比人工观测更客观、准确,更接近大气的实际情况,自动气象站观测具有明显的优势。

Based on data comparisons between automatic and manual observation in Jianyang during 2004 to 2005, we found that the highest temperature in automatic records is obviously higher than that of manual observation. In addition, the average wind speed in automatic station is greater than that in manual station, and the extreme relative humidity in automatic station is evidently greater than that of manual station, but there is no obvious differences in precipitation and pressure derivation. The data differences between automatic and manual station are mainly caused by their respective working theories, observation methods and calculations. Compared with manual observation, the automatic observation has evident advantages, such as more objective, accurate and better close to the reality of atmosphere.
