Detected Climatic Change in Global Distribution of Tropical Cyclones

May 4, 2020 – Although global mean temperature has been rising since the mid-twentieth century and can be attributed to increases in emissions of greenhouse gasses, the annual number of global tropical cyclones (TCs) has remained steady at around 86 since 1980. The limited length of observed TC data and the effect of multi-decadal variability have made it challenging to detect trends in TC activity on a global scale. There is a distinct spatial pattern to the trends in TC frequency of occurrence at a global scale since 1980. Significant decreases in the frequency of occurrence in the South Indian Ocean, as well as the western North Pacific, can be seen.

Tropical Cyclone Motion in a Changing Climate

April 22, 2020 – There is intense public and scientific interest in the question of whether slowly moving and highly destructive hurricanes, such as Harvey (2017), Florence (2018), and Dorian (2019), could become much more common with climate change. Using high-resolution large ensemble simulations, the authors investigated whether future anthropogenic warming could lead to a significant slowing of hurricane motion, and whether the observed trends of hurricane motion during past decades could be attributed to anthropogenic forcing.

Vegetation feedbacks during drought exacerbate ozone air pollution extremes in Europe

April 20, 2020 – Ground-level ozone exposure harms human and plant health, especially on hot summer days when pollution from cars and power plants fuels ozone formation. Due to regulatory changes, emissions of ozone precursors have been reduced markedly in Europe, yet ozone pollution episodes have not decreased satisfactorily in recent decades. The authors show that slow progress towards improving ozone air quality in Europe can be partly explained by declining rates of ozone removal by water-stressed vegetation in response to climate warming.

SPEAR – The Next Generation GFDL Modeling System for Seasonal to Multidecadal Prediction and Projection

April 10, 2020 – The models in use at GFDL for seasonal-to-decadal prediction have performed very well but are built off rather old model physics and other components. A multi-year effort was undertaken to build a next-generation seasonal-to-decadal prediction system that took advantage of many recent modeling advancements.


Where engineering meets artistry: A day in the life of a marine ecosystem modeler

Jessica Luo

March 12, 2020 – This is what they never tell you in school — that scientific research is fundamentally the discovery of the unknown, and that the winding path to discovery is inevitably filled with dead-ends and potholes. At times, it feels like there is more failure than success in our day-to-day work. In our jobs as research scientists, the ability to manage, communicate, and learn from failure is essential.


Storm-induced sea level spikes expected to increase on the Gulf and Atlantic coasts

Flooded town

February 13, 2020 – Using a new powerful NOAA global climate model, NOAA and partner researchers show that big storm-induced spikes in sea levels will increase in the future from the Gulf Coast to the Atlantic coast as warming progresses, but will be driven by differing forces. Stronger hurricanes will be the primary driver for storm surge spikes along the Gulf Coast while overall rising sea levels will lead to more storm surges along the East Coast, according to new research appearing in the Journal of Climate.

Changes in extreme precipitation and landslides over High Mountain Asia

February 11, 2020 – High Mountain Asia is home to both monsoonal rains and the largest concentration of glaciers outside the North and South Poles. With climate change, heavy rainfall will increase, especially in mountains near glaciers and glacial lakes. This will make landslides more likely and could present new hazards of landslides releasing a wall of water from glacial lakes, impacting communities and infrastructure located downstream.

Investigation of the global methane budget over 1980-2017 using GFDL-AM4.1

January 10, 2020 – Changes in atmospheric methane abundance have implications for both chemistry and climate, as methane is both a strong greenhouse gas and an important precursor for tropospheric ozone. The global network of methane surface observations over the past 3-4 decades indicates that methane went through a period of rapid growth from the 1980s to 1990s, nearly stabilized from 1999 to 2006, and then renewed its rapid growth.


GFDL Scientist Recognized with International Prize for Model Development

Baoqiang Xiang

December 23, 2019 – GFDL scientist Baoqiang Xiang has been awarded the International Prize for Model Development from the World Climate Research Programme (WCRP) and the World Weather Research Programme (WWRP). Dr. Xiang is being recognized for his skill in developing multiple modeling systems, and in particular for leading the development of GFDL’s next generation coupled atmosphere-ocean models for prediction on the challenging seasonal-to-subseasonal timescale.
