Phil Posted March 25, 2022 Report Share Posted March 25, 2022 Putting the SW US drought in context, as ugly as it’s been of late, it’s actually not unprecedented (even in the context of only the last 100 years, let alone the last 1000+). This is significant variability, offering the possibility that these trends could reverse in the coming years/decades. 2 Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...

Dan the Weatherman Posted March 25, 2022 Report Share Posted March 25, 2022 14 hours ago, TacomaWaWx said: Somethings definitely changed in Oregon in the last decade. Might just be the new normal in terms of climo. Went down there on a road trip in mid September all the way through central Oregon and back up I-5 through Eugene. Despite recent rainfall at the time there was pretty significant drought signs…especially in the central Oregon cascade crest. Something major IMO shifted around the 2011-12 or 2012-13 seasons that have led us into this terrible drought pattern here in California and much of the West in general including parts of Oregon. Whether it is the warming of the Arctic leading to the weakening of the polar jet, some shift in the Pacific Ocean circulation patterns, a flip in an unknown oscillation pattern that hasn't been identified yet, the AMO being in its positive phase for too long, or human induced climate change exacerbating the patterns that already cause dry conditions here, I know something happened in that time frame I mentioned above because it occurred almost like a flip of a switch! 2 Quote Link to comment Share on other sites More sharing options...

More clouds/higher RH can go a long way in capping surface temperatures and preventing vegetation from drying out. I have no idea how to look at the evolution of RH in the last couple decades, but in the last few summers it definitely feels like the dew point has been higher than previously. Probably one of the easier ways we could start to disentangle it would be to look at the evolution of summer low temperatures. Even if you'd expect summer temperatures (high and/or average) to be warming, you wouldn't exactly expect low temperatures to be warming if there was a drop in RH. That's not true. We see a relatively profound increase in low temperatures throughout the Western US (I only made graphs for stations in W. WA because I was lazy, but there's a clear trend in every station I checked from Vancouver, BC to Shasta, CA). Of course you could make an argument that a simple linear regression model based off individual years is not the best way to investigate this trend (which I agree with), but it is the easiest.

The former had no smoke, and the latter had lots of it. Edit - I also recall some frontal style rainfall in Junes of 2012/2013.

But low temperatures can absolutely increase with a drop in RH..especially if boundary layer mixing is increased (which is one way both UHI and GHG forcing keep surface temperatures higher at night). And even if there is no change in RH, the relationship between evaporation and temperature/humidity is not linear..warming temps with no change in RH% will still accelerate evaporation. And then there’s the question of cloud cover/insolation. You’re probably thinking of specific humidity in your initial assumption, which I’d tend to agree with insofar as the boundary layer is concerned, but even that is dependent on a number of external variables.

Phil Posted March 25, 2022 Report Share Posted March 25, 2022 There’s a reason summer 2019 saw a reduction in wildfire activity. It wasn’t some fluke. Warm season precipitation/cloud cover/RH matters. The evidence is incontrovertible.

Warm season precipitation/cloud cover/RH matters. The evidence is incontrovertible. Is there anyone in the world who would dispute that? Dry, sunny, high fire danger weather increases the risk of fires. Not exactly controversial. 1 Quote Everett Snowfall (510 feet elevation) Snow since February 2019: 91" 2023-24: 6" 2022-23: 17.5" 2021-22: 17.75" 2020-21: 14.5” 2019-20: 10.5" 2018-19: 24.75" Link to comment Share on other sites More sharing options...
