*to find the parcel that maximizes CAPE

I wonder if a possible method could be to start with the parcel with max theta-e in lowest 300 mb and with some really efficient code ;) check “adjacent” parcels that optimize the CAPE over the entire depth.

Max theta-e in the lowest 400 mb?

Beautiful!

One of my favorite places in the whole world

Finally captured a blue swallowtail butterfly in a photo today.

Very nice work and really interesting! Defining an”outbreak “ is certainly not easy. Thanks for your intriguing findings and for the discussion.

Thanks so much! I appreciate your efforts 😊

Hi Nick - How many tornadoes were in your total count?

Your work is so important and makes a real difference in people’s lives and safety. You matter and your work matters. Thank you for dedicating your talents to public service. Sending you support…

I feel the same way! I think they’re delightful!

Thanks Liz- that is so pretty! We have an open field behind us and tons of squirrels, and with our other feeders, we just feed everybody! May try some baffles with the camera feeder and a pole.

Here's wider view 😊🌪️

Oh, this?

Just a dust devil, seen from orbit.

From Mars orbit. And the dust devil is 20 kilometres tall.

This has to be the clearest and most detailed dust devil I’ve yet seen captured. Amazing!

What a beautiful tribute Elizabeth!

Congratulations to Roger Edwards on a brilliant career of service and contributions to our science. I wish him all the best in this next chapter.

[3/3] and with strong wind speeds at all heights. A proposed long-track tornado parameter (LTTP) was also developed.

[2/3] and that thermodynamic quantities had almost no discrimination capability for PL. In particular, there were lower thresholds for kinematic quantities beyond which almost no LTTs were reported. Some of the highest correlations with PL were found with SRH, BWD and SR surface winds at z < 2km

1/3 Based on ERA5 soundings near the start points and start times of 48,212 tornadoes from 1979-2022, we found larger amplitude kinematic quantities were necessary for long-track tornadoes (LTTs; pathlength PL ≥ 30 mi), as is the case for long-lived supercells (i.e. supports faster moving storms)

Our paper was just published in final form in Wea. Forecasting, “Environmental Conditions Associated with Long-Track Tornadoes.” journals.ametsoc.org/view/journal...
