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

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.

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.

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.

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/…

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

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

#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.

A review paper on this long standing research topic has been just published. Very excited! Lee, S. et al. On the future zonal contrasts of equatorial Pacific climate: Perspectives from Observations, Simulations, and Theories. npj Clim Atmos Sci (2022). doi.org/10.1038/s41612…

#Arctic air temperature rank by month over the satellite era - now updated through October. Come on... It's obvious what's going on. + Ranks: 1=warmest (red), 43/44=coldest (blue) + Download visual: zacklabe.com/arctic-tempera…

🚨 Yikes - yet another record high! Global ocean heat content now updated through September 2022... [Data (anomalies) & methods from NOAA NCEI: ncei.noaa.gov/access/global-…]

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

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

Striking🧐

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.]
