Meteorological factors may influence coronavirus disease 2019 (COVID-19) transmission. Due to the small number of time series studies, the relative importance of seasonality and meteorological factors is still being debated. From March 2020 to April 2021, we evaluated the impact of meteorological factors on the transmission of COVID-19 in Chennai, India. Understanding how the COVID-19 pandemic spreads over the year is critical to developing public health strategies. Correlation models were used to examine the influence of meteorological factors on the transmission of COVID-19. The results revealed seasonal variations in the number of COVID-19-infected people. COVID-19 transmission was greatly aggravated by temperature, wind speed, nitric oxide (NO) and barometric pressure (BP) during summer seasons, whereas wind speed and BP aggravated COVID-19 transmission during rainy seasons. Furthermore, PM 2.5, NO and BP aggravated COVID-19 transmission during winter seasons. However, their relationships fluctuated seasonally. Our research shows that seasonal influences must be considered when developing effective interventions.
气象因素可能会影响2019冠状病毒病（COVID-19）的传播。由于时间序列研究数量较少，季节性和气象因素的相对重要性仍在争论之中。2020年3月至2021年4月，我们评估了气象因素对印度钦奈COVID-19传播的影响。了解COVID-19大流行如何在一年中传播对于制定公共卫生策略至关重要。相关模型被用于检验气象因素对COVID-19传播的影响。结果揭示了COVID-19感染人数的季节性变化。在夏季，温度、风速、一氧化氮（NO）和气压（BP）极大地加剧了COVID-19的传播，而在雨季，风速和BP加剧了COVID-19的传播。此外，在冬季，细颗粒物2.5、NO和BP加剧了COVID-19的传播。然而，它们之间的关系随季节波动。我们的研究表明，在制定有效干预措施时必须考虑季节性影响。
