Dear BikerGeek, X-Air, and WeatherCat faithful,
*Sigh*, having a PhD which dealt in part with scientific methodology, don't get me started on the COVID-19 mess!!

Not sure “weather” has any effect. . . . .

I've noticed another puzzling phenomenon that definitely defies explanation. For decades, it has been noticed that weather patterns get locked into a 7-day cycle. Since there is no natural 7-day cycle, it has always been assumed to be due to human activity - although no satisfactory explanation for this has been found. COVID-19 has offered an interesting way to test if this cycle was due for example to the 5-day workweek and 2-day weekend cycles of human activity. At least in the San Francisco Bay Area, the 7-day cycle continues even if the normal commuting and weekend activities having been radically altered. So whatever explains the 7-day cycle, it isn't the commute patterns. So for the moment, whatever other havoc COVID-19 is causing, it isn't messing up with the weather . . . . . . at least any more than it is already messed up! . . . .

Cheers, Edouard
