| 摘 要： | 该文概述了造成自动观测与人工观测数据差异的各种原因，其中包括仪器的测量原理与观测方法不同，观测时间和空间不同，采样方式与算法不同，观测时次不同等等。通过对比分析基本气象要素，如气压、气温、地温、风向风速、降水、湿度等的两种观测数据，认为自动气象站的观测结果更接近大气中的实际情况。自动站对气压、气温和风向风速的观测有明显的优势，但在雨量累计量的测量和高温高湿下的湿度测量效果不理想。

| Abstract: | The many factors caused data differences of automatic and manual observation were described, including difference of measuring principles and observation method, differences of measuring time and space, difference of sampling mode and algorithm, difference of time level, and so on. Comparison between two objective data of basic meteorological elements, such as air pressure, temperature, wind direction, wind speed, precipitation, humidity etc, was conducted. It is found that observation results of automatic weather station are more objective and scientific than that of manual observation. It has a prominent advantage at an automatic weather station measuring air pressure, temperature, wind direction, wind speed. On measuring rainfall amount, although the automatic weather station has a defect as to provide accumulative rainfall amount, it can provide betimes message of rainfall amount, and so has its superiority on weather forecasting. On humidity measuring, although it cannot get a satisfactory observation in the circumstance of high temperature and high humidity, but it has an advantage in its bounds of moderation. |
