It's hydrologic new year! Not sure I'd go so far as "happy"

Centennial‐Scale Intensification of Wet and Dry Extremes in North America This study models seasonal drought and pluvial trends, merging reconstructions, observations, and projections from 850 to 2100 CE Results show widespread exacerbation of both extremes with overal...

A reminder the climate pattern we've seen in #Ohio the last two years (near record wet winter/spring followed by severe summer/early fall #drought) is predicted by #climatechange models and supported by observations. A #newnormal we all will have to deal with.

New research led by Kay Sung explores 1,250 years of precipitation trends across U.S. watersheds.

Using tree rings, climate model output, & non-stationary SPI, we show how climate change is shaping seasonal rainfall.

Water Use Across the United States Declines to Levels Not Seen Since 1970 Reductions in water use first observed in 2010 continue, show ongoing effort towards “efficient use of critical water resources.”

Across the US, population is increasing, but total water has decreased. All because per capita use decreasing. Efficiency and changing habits

Put simply, DC kept demand low and has sufficient water because of technology and the EPA regulations to increase adoption

NOAA's #GreatLakes Environmental Research Lab will be taking an "indefinite hiatus" from communications due to staff cuts. GLERL communicates critical weekly updates about the extent of harmful algal blooms in Lake Erie - like the one that left my hometown of Toledo without drinking water in 2014

Expected annual minima from an idealized moving-average drought index Abstract. Numerous drought indices originate from the Standardized Precipitation Index (SPI) and use a moving-average structure to quantify drought severity by measuring normalized anomalies in hydroc...

New paper - how does moving window length affect the annual minima? Relevant for SPI/SPEI #drought

Columbus Science Pub- Ohio's New Normal, After Climate Change with Dr. Climate's changing everywhere, including in Ohio. In January, we'll dive into the science of these changes with a local expert. Dr. Jim Stagge is an assistant professor at the Ohio State

In #Ohio? Worried about this summer's #drought? Want to know how tree rings tell us about climate change? Want to know what models predict about Ohio under #climatechange? Want pizza?

Come out to the Columbus Science Pub Jan 9 at 7:30pm.

Assessing decadal- to centennial-scale nonstationary variability in meteorological drought trends Abstract. There are indications that the reference climatology underlying meteorological drought has shown nonstationarity at seasonal, decadal, and centennial timescales, impacting the calculation of...

(4) We are only a week into December. It will be interesting to see where total Intermountain precip stands in March

(3) Finally, #AtmosphericRivers are more important for the coast, as we're seeing with the damage from this storm. They play less of a role in the Rockies (see our supplement), but it looks like this storm might infiltrate into the region and bring plenty of snow

(2) A reminder that there is a lot of natural variability in the climate system. Over the last century, #ElNino tends to decrease total winter (Dec-Feb) precip in Wyo, Utah, but individual storms don't always fall neatly into the long-term pattern

(1) Interesting timing with the massive #AtmosphericRiver in the Pacific NW. Under ongoing El Nino, we expect Pacific moisture to head south, not north
