Circling back on an earlier topic, a new paper suggests SARS-CoV-2 will likely be constrained by climate conditions.
The results are based on existing data so they may not be robust but it looks like the virus prefers cool and dry conditions. Specifically between 11°C to 25°C (52°F - 77°F). The strongest result is with humidity due to physics, higher humidity decreases transmission radius and the amount of time droplets remain airborne. It's similar, but the not the same as the flu.
Cooler temperatures do not allow for high absolute humidity. So in essence, the virus survives best in the temp/humidity range as air conditioned buildings.
Outside of conditioned spaces, the analysis indicates SARS-CoV-2 thrives in warm temperate climates between October to May and cold temperate climates between April and September. The virus is incapable of surviving for long in extreme hot or extreme cold environments.
From June to September, much of higher latitude regions of the southern hemisphere, like Argentina, Australia, Brazil, Chile, New Zealand, and Southern Africa will likely be become exposed to new outbreaks of SARS-CoV-2. Models also project highest latitude regions of the northern hemisphere to be badly hit by the Coronavirus during this period, including Canada and Russia, but also the Scandinavian countries. While northern hemisphere (chiefly Italy, Spain, France, Germany, UK, and USA) should see a reduction in SARS-CoV-2 infectections and then pick up again from September through May.
