With all these results in hand, there is a clear evidence that the wind could be a carrier of droplets containing concentration of COVID-19, while some case studied have been done for indoor and outdoor exposure with a wind speed of 2km/h, no mathematical model has been suggested to see in general how far such droplets could be transported. It was also observed that the transport followed a crossover behaviour, where during the first period, the transport followed a fading memory process but later a power law behaviour, with no steady state, this was very interesting as this shows that, when the COVID-19 infected person sneezed there were no wind effect, thus concentration released in the air with initial speed was able to spread like in the results described in [66] see Figure 8 below. ./cache/cord-295431-p9iy7uaf.txt ./txt/cord-295431-p9iy7uaf.txt
