摘要

针对室外热环境评价指标湿球黑球温度在实测和数值计算中都比较难获得的问题，在湿热地区广州夏季收集了空气干球温度、湿球温度、黑球温度、相对湿度、风速、太阳辐射和湿球黑球温度等数据，对收集的数据进行相关性分析和回归分析，相关性分析结果表明：空气温度、相对湿度、太阳辐射与湿球黑球温度具有一定的线性相关度，可以采用上述三个气象因子作为湿球黑球温度的简化计算参数；回归分析结果表明：回归的关联式与实测湿球黑球温度的相关性较高，并且满足多元线性回归的各项检验，认为该回归方程具有较高的可信度，可以在城市热环境的实测评价和数值预测过程中，作为湿球黑球温度的简化计算方法应用。

Abstract

The wet bulb globe temperature (WBGT) is difficult to measure and calculate in field observation and numerical simulation. To solve this problem

the air dry bulb temperature

wet bulb temperature

globe temperature

relative humidity

mean air velocity

solar radiation and wet bulb globe temperature in Guangzhou

P. R. China

first were collected during the summer (July). Next

correlation and regression analyses were used to derive a simplified model for calculating WBGT. The results show that dry bulb temperature

relative humidity

solar radiation

mean air velocity and WBGT were interrelated to some extent. These four parameters with high linear correlation can be used to predict WBGT in a simplified model with high precision. The simplified WBGT model can be used in field observation and simulation research regarding urban thermal environments.
