It's important to spread awareness that these tools aren't the objective truth, but I think, in this case, people are attributing malice to the technology when the source of the problem is our own limitations as a society.

@HydroLejo check pms ;-)

@AirTalk @snow_d0c Thank you for having @UCB_CSSL and I on the show, Larry! 🙏 It was fun to discuss the intersections of California's people and its environment and the challenges we face. More snow on the way! ☃️🏔️🌨️🔥🌞🌊🚰🌲🌴

Thanks to Benjamin (@_Dr_OpS_) and Andrew (@snow_d0c) for joining today's program. You can find the research that kicked off this conversation via the link below. agupubs.onlinelibrary.wiley.com/doi/10.1029/20…

As Wildfires Increase & Reach Higher Elevations, California’s Snowpack Is Melting Faster We were joined by Benjamin Hatchett (@_Dr_OpS_) of @DRIScience and Andrew Schwartz of @UCB_CSSL. Our audio will be up later this afternoon at the link below. kpcc.org/show/airtalk/2…

@TomDilts1 @ACsank @UnrGeography debris flow innundation (orangish features) issuing out of the Thomas Fire (brown fill) during the 2018 Montecito Debris Flow event. a layer to drape over the elevation and hillshade before annotating a bit. but gotta leave reviewers at least some cartographic easter eggs to find

@_Dr_OpS_ @ACsank @UnrGeography All great titles. What is this one by the way?

@TomDilts1 @ACsank @UnrGeography Alt Title 3 (The Age Old Classic) "What was I trying to do here?"

@dfosterhill that's also how you quickly bump up the vertical for the day/week/year 🤣⛷️

@nplareau cool! (pun intented lol). bonus points for Froude number as eqn 1. Now you gotta study the Martis Valley Seiche. But aren't these oscillations you're seeing at very fine timescales (KH waves?) whereas the sieches in the paper are basin scale? maybe i'm misinterp'ing?

@_Dr_OpS_ I think mostly wind stress exciting seiches in the stratified air mass (aka basin-scale oscillations), though fluxes from the reservoirs could make some impacts. Here is a study I did of some "dynamic displacements" of cold air pools in SLC long ago: link.springer.com/content/pdf/10…

1/2: Some other interesting things this AM: Strong nocturnal inversion in the #Truckee basin, including a gentle sloshing of the fog-filled cold air apparent in (1) the attached video, and (2) the quasi-regular oscillations in surface temp/RH observations (next tweet) #CAwx

@nplareau what's the key driver(s) of this oscillation? sloshing and shifting roles/directions of heat fluxes? #thingsyoudontseeinhourlyRAWS

Here is a temperature trace from the bottom of the Martis Creek/Valley along with map showing the pooling of the coldest air.

@nplareau @skiswm ha! they should have taken my mtn wx class. I tell students to always camp in the junipers (thermal belt) if they want to wake up early and warm with unfrozen water bottles. however, it sounds like they were well-insulated by deep snow so maybe a wash?

@skiswm I often wonder if the Donner Party had found a higher elevation camp how many calories they'd have saved. Usually runs 20 degrees warmer at my house in TD than by the lake...

@nvglaciers @nevada_water tree shadow image is awesome!

@AaronPutnam14 Behold the North American Dipole!

T-shirt weather here in Maine today with temps > 10°C above average. Temps are well above average (1.1°C) across much of the Northern Hemisphere (western North America being a notable exception). I can’t remember setting the clocks under such conditions…

@Jessica_D_Clark @HydroCycler super cool, thanks for that. the clouds add such a nice dimension. I may be biased though about the clouds, here's the Ansel Adams print above my desk 😁

@_Dr_OpS_ @HydroCycler This is most likely an Ansel Adams image from 1932. anseladams.com/the-golden-gat…
