On December 10, 2021, one of the most destructive winter tornado outbreaks developed in northeastern Arkansas. This tornado outbreak, later coined as the Quad-State Tornado Outbreaks by the news media, struck portions of the Ohio Valley, including Missouri, Illinois, Tennessee, and Kentucky, from December 10 to 11, 2021. According to the National Oceanic and Atmospheric... Continue Reading →
A new study published in Science (Zhou and McManus, 2024) reconstructed the land ice melting (or discharge) rate during the intermittent events of ice melting in the last glacial period (i.e., Heinrich events). The study showed that the present-day Greenland Ice Sheet melting rate (since the 1980s) is comparable to that during weak-to-moderate strength Heinrich events. This... Continue Reading →
This short essay by Daniel C. Laughlin is beneficial not only for young ecologists but also for all scientists both young and old. The author spoke of three elements of ecology: natural history, quantitative reasoning, and communication. If you are an oceanographer or climate scientist, you may want to substitute "natural history" with "observational data" for... Continue Reading →
The Atlantic Meridional Overturning Circulation (AMOC) transports warm and salty upper ocean water to the subpolar North Atlantic where the upper ocean releases some heat to the atmosphere. Due to the surface cooling and the high salinity (i.e., salty), the upper ocean water becomes heavier and thus sinks down to the deep ocean and then... Continue Reading →
As a climate scientist, I have worked and interacted with many weather scientists in the past 20 years or so. I am also currently in a task force team to advance subseasonal (2~4 weeks) forecasts of severe weather activity in the U.S. I have learned so much from weather scientists about how longer-term climate processes...

Two important atmospheric jet streams that shape the extratropical zonal wind field in both hemispheres are the subtropical jet and the subpolar jet. The subtropical jet is located around 30° latitude line at the boundary between the Hadley cell and the Ferrel cell, and is predominantly a high-altitude feature. Since it is largely in thermal-wind... Continue Reading →
Michael White is a climate science editor for Nature. He posted on Twitter a list of useful tips for climate scientists to consider before they submit their work to Nature or other journals. Personally, I would like to stress his suggestion to avoid subjective wording like “unprecedented”, “dramatic”, and “remarkable”. Such a subjective word gives... Continue Reading →
Throughout my career, I have published many scientific papers and reviewed even more papers. So, I have received or encountered many interesting reviews. Here are the 3 most memorable comments that I have received so far. #3) "The paper is very poorly written, lacks objective detail, and makes fatal flaw assumptions about the role of...

Atlantic Niño is the Atlantic counterpart of El Niño in the Pacific, often referred to as El Niño's little brother. It was previously thought to have only regional influence on rainfall variability in West Africa, but a growing number of studies have shown that Atlantic Niño also plays an important role in the development of...

As of July 2023, the developing El Niño in the Pacific has already exceeded its sea surface temperature (SST) anomalies of 1°C in Niño3.4 region (central Pacific) and 3°C in Niño1+2 region (far eastern Pacific). This is the first time to have those SST thresholds exceeded since the development of 1997-98 "supper El Niño" in... Continue Reading →
