The novel coronavirus disease 2019 (COVID-19), which first emerged in Hubei
province, China, has become a pandemic. However, data regarding the effects of
meteorological factors on its transmission are limited and inconsistent. A
mechanism-based parameterisation scheme was developed to investigate the
association between the scaled transmission rate (STR) of COVID-19 and the
meteorological parameters in 20 provinces/municipalities located on the plains in
China. We obtained information on the scale of population migrated from Wuhan,
the world epicentre of the COVID-19 outbreak, into the study
provinces/municipalities using mobile-phone positioning system and big data
techniques. The highest STRs were found in densely populated metropolitan areas
and in cold provinces located in north-eastern China. Population density had a
non-linear relationship with disease spread (linearity index, 0.9). Among various
meteorological factors, only temperature was significantly associated with the
STR after controlling for the effect of population density. A negative and
exponential relationship was identified between the transmission rate and the
temperature (correlation coefficient, -0.56; 99% confidence level). The STR
increased substantially as the temperature in north-eastern China decreased below
0 °C (the STR ranged from 3.5 to 12.3 when the temperature was between -9.41 °C
and -13.87 °C), whilst the STR showed less temperature dependence in the study
areas with temperate weather conditions (the STR was 1.21 ± 0.57 when the
temperature was above 0 °C). Therefore, a higher population density was linearly
whereas a lower temperature (<0 °C) was exponentially associated with an
increased transmission rate of COVID-19. These findings suggest that the
mitigation of COVID-19 spread in densely populated and/or cold regions will be a
great challenge.
