"...
“Coronavirus disease . . . has established significant community spread in cities and regions along a narrow east-west distribution roughly along the 30-50 N’ corridor at consistently similar weather patterns of average temperatures of 5-11C, combined with low . . . humidity,” they wrote. In other words, it spreads in places like Britain.

For coronavirus in Britain, the reproduction number is somewhere between 2.5 and 3.5.
In their paper, researchers from Beihang University calculated the reproduction number for all 100 Chinese cities with more than 40 cases. Then they looked at the weather.
For each degree change in average temperature, the number fell by 0.04. This is indeed good news for Britain, but not great news. In August, we can expect the reproduction number to drop by about 0.6 or, by less than the present uncertainty we have on its value. So it might fall to somewhere between 1.9 and 2.9.
