Human thermal comfort is influenced by different climatic parameters. The effect of rain and snow events on human thermal comfort has been less explored in the available literature. The work presented here investigates outdoor and indoor thermal comfort using the physiological equivalent temperature (pet) and wind chill temperature (WCT) indices and Givoni bioclimatic chart for rainy and snowy days as well as a day prior to and a day post snow and rain events in Ardabil. Results indicated that snow and rain events have cooling effects on both indoor and outdoor thermal sensation. The cooling effect of rainy and snowy days is higher than a day prior to and a day post events. Also, the cooling effect of the snow and rain increases by the intensity of the events (> 10 mm/day). Based on the PET and WCT outputs, the cooling effect of the snow events with intensity higher than 10 mm a day is about 1.77 and 0.80 °C less than events under 10-mm a day intensity. The same pattern was observed for rain events. Analysis of the cooling effect of event duration on outdoor thermal comfort indicated that the events with more than 2-day duration have more cooling effect on thermal sensation. Finally, due to different cooling effects of snow and rain events on indoor thermal sensation, different types of bioclimatic strategies should be used inside the buildings during snowy and rainy days in Ardabil.

人类的热舒适性受到不同气候参数的影响。现有文献中很少探讨雨雪事件对人体热舒适性的影响。此处介绍的工作使用生理等效温度（pet）和风寒温度（WCT）指数以及Givoni生物气候图表来研究雨天和下雪天以及下雪天和下雪天之前和之后的室外和室内热舒适度在Ardabil。结果表明，雪和雨事件对室内和室外的热感都有冷却作用。雨雪天的降温效果比事件发生前一天和事件发生后的一天都高。而且，雪和雨的冷却效果会随着事件的强度（> 10 mm /天）而增加。根据PET和WCT的输出，每天强度大于10毫米的降雪事件的降温效果比每天强度为10毫米的降雪事件的降温效果低约1.77和0.80°C。对于降雨事件，观察到了相同的模式。对事件持续时间对室外热舒适性的冷却效果的分析表明，持续时间超过2天的事件对热感的冷却作用更大。最后，由于雪和雨事件对室内热感觉的冷却效果不同，因此在下雪和雨天，在Ardabil，建筑物内应使用不同类型的生物气候策略。对事件持续时间对室外热舒适性的冷却效果的分析表明，持续时间超过2天的事件对热感的冷却作用更大。最后，由于雪和雨事件对室内热感觉的冷却效果不同，因此在下雪和雨天，在Ardabil，建筑物内应使用不同类型的生物气候策略。对事件持续时间对室外热舒适性的冷却效果的分析表明，持续时间超过2天的事件对热感的冷却作用更大。最后，由于雪和雨事件对室内热感觉的冷却效果不同，因此在下雪和雨天，在Ardabil，建筑物内应使用不同类型的生物气候策略。
