Seasonal predictability of baroclinic wave activity

npj Climate and Atmospheric Science, 2021
Midlatitude baroclinic waves drive extratropical weather and climate variations, but their predictability beyond 2 weeks has been deemed low. Here we analyze a large ensemble of climate simulations forced by observed sea surface temperatures (SSTs) and ...

Improving Global Weather Prediction in GFDL SHiELD Through an Upgraded GFDL Cloud Microphysics Scheme

Journal of Advances in Modeling Earth Systems, 2022
We describe the third version of the Geophysical Fluid Dynamics Laboratory cloud microphysics scheme (GFDL MP v3) implemented in the System for High‐resolution prediction on Earth‐to‐Local Domains (SHiELD).

Future changes in boreal winter ENSO teleconnections in a large ensemble of high-resolution climate simulations

Frontiers in Climate, 2022
The impacts of the El Niño-Southern Oscillation (ENSO) are expected to change under increasing greenhouse gas concentrations, but the large internal variability of ENSO and its teleconnections makes it challenging to detect such changes in a single ...

Volcanic Drivers of Stratospheric Sulfur in GFDL ESM4

Journal of Advances in Modeling Earth Systems, 2023
Stratospheric injections of sulfur dioxide from major volcanic eruptions perturb the Earth's global radiative balance and dominate variability in stratospheric sulfur loading.

Sensitivity of nitrate aerosols to ammonia emissions and to nitrate chemistry: implications for present and future nitrate optical depth [PDF]

Atmospheric Chemistry and Physics, 2016
We update and evaluate the treatment of nitrate aerosols in the Geophysical Fluid Dynamics Laboratory (GFDL) atmospheric model (AM3). Accounting for the radiative effects of nitrate aerosols generally improves the simulated aerosol optical depth ...

Revisiting the Impact of Sea Salt on Climate Sensitivity

Geophysical Research Letters, 2020
Recent laboratory and field studies point to an increase of sea salt aerosol (SSA) emissions with temperature, suggesting that SSA may lower climate sensitivity.

Ocean Ammonia Outgassing: Modulation by CO2 and Anthropogenic Nitrogen Deposition

Journal of Advances in Modeling Earth Systems, 2020
The imprint of anthropogenic activities on the marine nitrogen (N) cycle remains challenging to represent in global models, in part because of uncertainties regarding the source of marine N to the atmosphere.

Limited surface impacts of the January 2021 sudden stratospheric warming

Nature Communications, 2022
Subseasonal weather prediction can reduce economic disruption and loss of life, especially during “windows of opportunity” when noteworthy events in the Earth system are followed by characteristic weather patterns.

Ocean Biogeochemistry in GFDL's Earth System Model 4.1 and Its Response to Increasing Atmospheric CO2

Journal of Advances in Modeling Earth Systems, 2020
This contribution describes the ocean biogeochemical component of the Geophysical Fluid Dynamics Laboratory's Earth System Model 4.1 (GFDL‐ESM4.1), assesses GFDL‐ESM4.1's capacity to capture observed ocean biogeochemical patterns, and documents its ...
