Impacts of COVID-19 emissions reductions remain murky in the oceans

Dec. 11, 2020

As the COVID-19 pandemic took hold in the first half of 2020, humans around the world stopped moving and making, resulting in a 9% drop in the greenhouse gas emissions at the root of climate change.

Climate Variability Diagnostics Package for Large Ensembles (CVDP-LE)

Dec. 4, 2020

The Climate Variability Diagnostics Package for Large Ensembles (CVDP-LE) developed by NCAR's Climate Analysis Section is an automated analysis tool and data repository for exploring internal and forced contributions to climate variability and change in coupled model “initial-condition” Large Ensembles and observations.

Radiosonde observations of environments supporting deep moist convection initiation during RELAMPAGO-CACTI

Dec. 4, 2020

This study examines near-cloud environments from RELAMPAGO-CACTI to identify mesoscale ingredients affecting storm initiation. Null events arguably have the most convective potential but are limited ambient dry air.

Marine wild-capture fisheries after nuclear war

Dec. 4, 2020

We used an Earth system model and an offline fisheries model to demonstrate a serious decline in marine fisheries following a nuclear conflict. If we ran out of food on land due to darkening skies, we would not get much caloric relief from the ocean.

Does the rotational direction of a wind turbine impact the wake in a stably stratified atmospheric boundary layer?

Dec. 4, 2020

Stably stratified atmospheric boundary layers are often characterized by a veering wind profile, in which the wind direction changes clockwise with height in the Northern Hemisphere.

Nuclear war could take a big bite out of the world’s seafood

Nov. 10, 2020

A new study reveals the damage that a nuclear war might take on wild-caught seafood around the world, from salmon to tuna and even shellfish.

Can machine learning improve the model representation of turbulent kinetic energy dissipation rate in the boundary layer for complex terrain?

Oct. 2, 2020

Current turbulence parameterizations in numerical weather prediction models at the mesoscale assume a local equilibrium between production and dissipation of turbulence

How wind speed shear and directional veer affect the power production of a megawatt-scale operational wind turbine

Oct. 2, 2020

Most megawatt-scale wind turbines align themselves into the wind as defined by the wind speed at or near the center of the rotor (hub height).

A new study of ocean salinity finds substantial amplification of the global water cycle

Oct. 2, 2020

Water and its movements within or between atmosphere, land, and ocean defines the global water cycle and is central to the climate system.
