Abstract The changes in humidity levels during the Diwali festivities have been examined over a period of 13 years at three Indian metro cities: Ahmedabad, New Delhi and Kolkata. A small short term increase in relative humidity even in the absence of transport of humid air from Arabian Sea and Bay of Bengal has been observed. The relative humidity levels were found to be exceeding the ambient levels during night and lying below the ambient levels during morning hours, indicating an increase in the survival rates of viruses responsible for the transmission of viral infections, as well as triggering immune-mediated illnesses such as asthma during Diwali.

印度排灯节期间相对湿度的短期变化

摘要 在 13 年的时间里，在印度三个地铁城市：艾哈迈达巴德、新德里和加尔各答，对排灯节庆祝活动期间湿度水平的变化进行了研究。即使在没有来自阿拉伯海和孟加拉湾的潮湿空气运输的情况下，相对湿度也会在短期内小幅增加。发现相对湿度水平在夜间超过环境水平，而在早晨低于环境水平，表明导致病毒感染传播的病毒存活率增加，并引发免疫介导的疾病，如作为排灯节期间的哮喘。
