New Study Reveals Interdecadal Intensity Peaks in the Madden–Julian Oscillation

New research uses reanalysis datasets (including one from NOAA) to show how the Madden-Julian oscillation (MJO) exhibits 12- to 20-year periods around peak intensity and theorizes on the physical mechanisms responsible. 

Quantifying Ice Nucleating Particles in Western Wildfire Smoke Plumes 2 February 2021

Quantifying Ice Nucleating Particles in Western Wildfire Smoke Plumes

Using data sampled from wildfires across the US in the 2018 Western Wildfire Experiment for Cloud Chemistry, Aerosol Absorption, and Nitrogen (WE-CAN) campaign, this study is the first to quantify ice nucleating particles within wildfire smoke plumes in the free troposphere.

Coastal Flood Risks Amplified by Extreme Sea Level Variability 1 February 2021

Coastal Flood Risks Amplified by Extreme Sea Level Variability

Researchers from the University of Central Florida and the University of South Florida recently published a study that shows how incorporating decade-long variations in extreme sea level (ESL) events, such as storm surge, in coastal flooding risk assessments can dramatically increase the severity of expected flooding and the associated economic losses.
