在两个调查期间，在短暂的季节（14个工作日在2009年秋季和15个工作日在2010年春季）967名游客在两个内城广场的塞格德（匈牙利）被问及他们的热环境的估计。主观评估的热感觉，个人的气候参数的看法和偏好的相互关系进行了分析，以及他们的连接与当时的热条件[空气温度，相对湿度，风速，平均辐射温度和生理等效温度（PET）]。热感觉与空气温度和太阳辐射感知呈强正相关，而风速和空气湿度感知具有负（且较弱）影响。如果一个参数被认为是低或弱，那么它通常是希望更高或更强。在湿度的情况下，这种负相关性最弱。在基本气象参数中，匈牙利人对风的变化最为敏感。PET = 29A ℃以上，人们通常更喜欢较低的空气温度和较少的太阳辐射。被访者感知的温度值与PET相关性更强，但其平均值与空气温度更相似。还发现，匈牙利人在短暂的季节的平均热感觉取决于PET根据二次函数（R（2）= 0.912），因此，当地人的热舒适范围不同于通常采用的。
During two investigation periods in transient seasons (14 weekdays in autumn 2009 and 15 weekdays in spring 2010) 967 visitors in two inner city squares of Szeged (Hungary) were asked about their estimation of their thermal environment. Interrelationships of subjective assessments-thermal sensation, perceptions and preferences for individual climate parameters-were analyzed, as well as their connections with the prevailing thermal conditions [air temperature, relative humidity, wind velocity, mean radiant temperature and physiologically equivalent temperature (PET)]. Thermal sensation showed strong positive relationships with air temperature and solar radiation perception, while wind velocity and air humidity perception had a negative (and weaker) impact. If a parameter was perceived to be low or weak, then it was usually desired to be higher or stronger. This negative correlation was weakest in the case of humidity. Of the basic meteorological parameters, Hungarians are most sensitive to variations in wind. Above PET = 29A degrees C, people usually prefer lower air temperature and less solar radiation. The temperature values perceived by the interviewees correlated stronger with PET, but their means were more similar to air temperature. It was also found that the mean thermal sensation of Hungarians in transient seasons depends on PET according to a quadratic function (R (2) = 0.912) and, consequently, the thermal comfort ranges of the locals differ from that usually adopted.
