"The density heatmaps of COVID-19 cases in the selected cities in association with temperature and specific humidity at different time lags. The red histogram above each heatmap is the histogram of COVID-19 cases in relation to temperature while the blue histogram beside each heatmap is the one in relationship to specific humidity."

A density map was used to see the association between COVID-19 cases and the combined effect of specific humidity and air temperature. This was done by evaluating the daily COVID-19 reports by the combined mean specific humidity and mean air temperature. More COVID-19 cases were found in conditions with low specific humidity (2-6 g/kg) and low temperature (2-11 C). This association also holds true in different incubation times.
