摘　　要：利用2022年8月~2023年7月的平行观测数据,对自动气象站自然通风防辐射罩和百叶箱气温观测的数据差异进行了分析,探讨了海南热带地区不同时间条件下太阳辐射强度和降水对温度偏差的影响。结果表明,自然通风百叶箱和防辐射罩气温观测系统在热带地区均能提供可靠的气温数据,但在不同环境条件下存在一定差异。防辐射罩的气温分钟值和日最值的平均值比百叶箱偏低约0.1℃;太阳辐射对防辐射罩与百叶箱气度测量有一定影响,但不明显;在气温发生较大变化时(午后降水)温度偏差较大,防辐射罩的气温下降速度大于百叶箱的气度下降速度,百叶箱温度变化滞后。This paper analyzes the differences in temperature observations between natural ventilation solar radiation shield and thermometer screen at automatic weather stations,utilizing parallel observation data from August 2022 to July 2023.It explores the impact of solar radiation intensity and precipitation on temperature deviations under varying temporal conditions in Hainan's tropical region.The results indicate that both natural ventilation thermometer screens and solar radiation shields can provide reliable temperature data in tropical areas,however,there are notable discrepancies under different environmental conditions.Specifically,the average minute values and daily maximum values of temperatures recorded by solar radiation shields are approximately 0.1℃lower than those measured by thermometer screens.While solar radiation has a certain influence on temperature measurements from both systems,this effect is not pronounced.During significant temperature fluctuations(such as afternoon rainfall),larger deviations in temperature were observed,the rate of decrease in temperature for the solar radiation shield was greater than that for the thermometer screen,resulting in a lagging response of the latter to changes in ambient conditions.
