摘　　要：船舶气象仪是海上航行、海上气象要素观测的基础测量仪器。文中介绍了两台气象仪的海上现场比测试验。结果显示,两台气象仪温度、相对湿度、气压数据具有良好的一致性,其相关系数在0.9以上;风速由于受到实际环境条件的影响,导致其数值有较大差异,但是从趋势图还是可以看出有较好的一致性;经方向转换后实际风向数据相差不大。总体来说被测船舶气象仪的工作稳定性良好,测量数据可靠。Shipboard Meteorological Instrument is used in meteorological observation at sea and sailing. The comparative test on the sea between two Shipboard Meteorological Instruments is introduced in this paper. The result indicated that the instruments had high internal consistency reliability in atmospheric temperature relative humidity and atmospheric pressure. The correlation results of different instruments are more than0. 9. Though there were some differences between the data of wind speeds for the actual environmental conditions,they had high internal consistency reliability in the tendency chart. The differences of wind direction were small when they were converted. As a whole,the performance and stability of Shipboard Meteorological Instrument are stable.
