Interesting thoughts Mike, a nice September with plenty of sun and keep those windows open at home, and way more important .. keep the windows open on public transport, I hope this message gets pushed hard soon.
Humidity I raised before SnowBear, ,the higher the humidity leads to heavier droplets, so they fall out of the air more quickly, think this has been known for years?
Lets see where low solar combined with week la nina takes us.
