Hi Mark,
First, thank you for what you do for meteorology. I thoroughly enjoy your analyses.
As you pointed out, the Arctic Blast was more than just a bitter cold snap and heavy snow. It was a series of warm and cold sub events, a big event followed by several milder warm and cold events.
I was wondering if there is any correlation between the the Blast and the River that hit California the last couple of weeks:
1) Do Rivers always follow Blast events?
2) Do Blasts always proceed Rivers?
3) Do Blasts and Rivers occur in the same part (early) of the winter season? I vaguely recall Rivers occurring in other parts of the winter season.
Thank you for giving consideration to my questions.

Great question, Jim! As best I can tell, along with what I’ve learned in meteorology, a connection between arctic blasts and the atmospheric river is very weak. Both are caused by such different forces. For instance, the atmospheric river is very heavily dependent upon the behavior of El Nino and La Nina. The patterns those two choose to take has a big impact on airflow into California from the Pacific. Arctic blasts are dependent upon the arctic oscillation, which is the behavior of the “pool” of arctic air at the North Pole. As that air rotates about the pole it can become unstable and detach from the main batch of cold air. It can then make its way southward into the US. Moisture from the atmospheric river can then interact with that cold air, but I’m not aware of either one directly influencing the other, especially with them being so far apart and so independent upon each other (at least according to what we currently understand). I hope this helps!
