Potential Influences of Volcanic Eruptions on Future Global Land Monsoon Precipitation Changes

April 2, 2021

Future climate projections generally omit major volcanic eruptions but such events are likely to be important. In this work Dr. Man and colleagues show that projections of monsoon rainfall are importantly impacted by eruptions and could delay the time of emergence of anthropogenic influence by five years on average over about 60% of the GLM area.

Upper Ocean Temperatures Hit Record High in 2020

April 2, 2021

Ocean heat content reached a maximum observed level in 2020, driven by the continual human-driven warming of the climate system.

Marine Heatwaves Becoming More Intense, More Frequent

April 2, 2021

The 2019 Northeast Pacific marine heatwave was amplified by natural, multi-decadal shoaling of the ocean mixed layer; anthropogenic mixed layer shoaling will amplify marine heatwaves in the future.

Global and Regional Patterns in High Ice Water Content Conditions

April 2, 2021

High ice water conditions (HIWC) can cause jet engine failure or damage. This study provides an analysis of the frequency and location of HIWC over most of the globe using space-borne radar and lidar observations.

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.
