And global sea-ice extent has now set a new *all-time* record low...
➡️ Arctic (2nd lowest on record for date) + Antarctic (lowest on record for date)
[Graphics: zacklabe.com/global-sea-ice…. Data from nsidc.org/data/seaice_in… for the satellite-era. I am using a 5-day running mean.]

Thanks to my friend at CSU, Shim, we drove in the Rocky mountain national park and enjoyed these beautiful sceneries.

In wintertime, we argue that enhanced planetary-scale eddy heat flux regulates the equator-to-pole temperature gradient (mainly Arctic warming), and synoptic-scale eddies respond to these changes in meridional gradient, based on previous studies.
English
I am very excited to share my new paper with Sukyoung Lee (Penn State) about the causes of synoptic-scale eddy heat flux decline! We show that high-latitude land warming is a main driver of its declining trend during summer.

My colleague Yushi's lunchtime seminar made me search the current Antarctic sea ice extent, and it is an obvious outlier.

The lack of #Antarctic sea ice going into the new year is clearly an outlier compared to any other year in our satellite record.

🚨 Yikes - yet another record high! Global ocean heat content now updated through September 2022...

#Arctic air temperature rank by month over the satellite era - now updated through October. Come on... It's obvious what's going on.

A review paper on this long standing research topic has been just published. Very excited!

#Arctic climate rankings are in for September 2022: zacklabe.com/archive-2022/. Aside from Greenland, it was a pretty unremarkable month compared to many recent years.

WATCHING this moderate risk for excessive rainfall in southern California day 3 (Friday) with historic moisture influx from Hurricane Kay! I am considering a chase out there for flash flooding and debris flows off the wildfire burn scars. Cloud cover should break the heat wave

Truly incredible heat in California today with many cities setting new ALL-TIME record highs. Not just for the date or for September, but for any time of year in recorded history 😲 #CAWx

ICYMI: The tropical Pacific appears to be hopelessly devoted to La Niña for at least the early part of winter. If La Niña lasts through winter, this will be only the third time with three La Niña winters in a row in our 73-year record. climate.gov/news-features/…

A friend of mine is moving out and having a road trip from the central Pennsylvania to Irvine, California next week. Wish him best of luck. Someday I want to try that as well with my younger sister in LA.

Here's a look at forecast high temperatures and their departure from climatology for #today - A super comfortable, less humid and beautiful day in the East with below normal highs - Above normal highs in much of the Plains - Below normal highs from the monsoon in the Southwest

The North Pacific SST blob is again noticeable here in every panel. I am curious about its impact on the summertime North Pacific storm track.

This result reminds me of the recent meeting in the GFDL about the resolution dependence of the precipitation response from climate models. High resolution really matters for assessing the hydroclimate variability.
Daniel Swain@Weather_West
Both ARkHist & ARkFuture generate huge amounts of precipitation in California, but ARkFuture scenario is considerably wetter (45% so on a statewide basis, & locally 80% wetter). Some mountain areas see 30-day precip >60 inches in ARkHist, and >100 inches in ARkFuture! (5/n)

It may seem a bit strange to be talking about rising risk of a California #megaflood amidst severe #CAdrought. But it's not as paradoxical as it might seem at first glance--a topic I discuss extensively in my new Weather West overview of our work: (14/n) weatherwest.com/archives/16626

I tweet first and then check its grammar. A chronic habit of author's proof.
