Schematic representation of the atmospheric “non-frontal” component
New perspectives regarding Gulf Stream and Kuroshio Extension influence on the atmosphere

New research illustrates that the key to recognizing the influence of the Gulf Stream and Kuroshio Extension on the seasonal mean and longer-term climate is through a proper understanding of how the ocean influences atmospheric fronts.

Boxplots showing how well model forecasts capture the observations between the two winter seasons, 2016–17 minus 2015–16,
California winter precipitation linked to the Arctic Oscillation

California precipitation is well forecast when the Arctic Oscillation phase is correctly captured by a state-of-the-art forecast system, GloSea5.

Schematic representation of proposed dynamical mechanisms in summer.
The influence of Arctic amplification on mid-latitude summer circulation

Researchers conduct a comprehensive review of research on summer weather stalling, focusing on the influence of Arctic amplification and how it could interact with other factors influenced by climate change.

Subsurface ocean heat content anomalies regressed onto low-pass filtered time series of eastern tropical Pacific sea surface temperature anomalies. The black boxes outline the eastern (10°–20°S, 100°–120°E) and western (10°–20°S, 50°–90°E) Indian Ocean, showing the east-west dipole structure
Pacific influences decadal Indian Ocean heat content via two distinct mechanisms

In two recent papers, Jin and coauthors investigated how decadal variations of subsurface ocean heat content (50–300 m) in the Indian Ocean respond to conditions in the Pacific region.

simple linear model accounting for changes in drying ratio and mean source distance (MSD)
Global patterns of evaporation and precipitation leave a traceable isotopic fingerprint

A new study shows that a simple linear model that accounts for changes in mean source distance, as well as the local drying ratio, can successfully replicate water isotopic variations in space and time.

The Observational Large Ensemble (Obs-LE) can be used to assess the relative roles of internal variability and anthropogenic influence on 50-year trends in (a-b) temperature and (c-d) precipitation over land.
Developing Observational Large Ensembles for climate variability

Researchers have developed a complementary approach to creating ensembles for seasonal-average temperature and precipitation over land that can also be used to study internal variability.

2019 Call for new US CLIVAR working groups

Optional hike led by Large Ensembles Working Group members

Requests are now being accepted for one new US CLIVAR-sponsored working group for 2020. Submissions are encouraged from the US climate science community. All documents must be submitted by October 11, 2019. The next call for working groups will be in September 2020.

Fall 2019 call for US CLIVAR-supported workshops

Air-Sea Workshop

Requests are now being accepted for US CLIVAR-sponsored workshops. Submissions are encouraged from the US climate science community and their collaborators. All documents must be submitted by September 27. The next call for workshops will be in spring 2020. 

AMS 100th Annual Meeting, CLIVAR sessions of interest

AMS 100th Anniversary

The American Meteorological Society will be hosting its 100th Annual Meeting January 12-16 in Boston, Massachusetts. The annual theme for the upcoming AMS Annual Meeting is The AMS Past, Present and Future: Linking Information to Knowledge to Society (LINKS). Included are a number of sessions relevant to the US CLIVAR community. Abstract deadlines have been extended. Be sure to check out the Programs page for deadline dates.

CLIVAR town hall & sessions at 2020 Ocean Sciences Meeting

2020 Ocean Sciences Meeting

The 2020 Ocean Sciences Meeting will be held February 16-21 in San Diego, California. We have started to put together a list of US CLIVAR-sponsored sessions along with Town Halls, events, workshops, and other sessions that may be of interested to the US CLIVAR community. This is an ongoing list that will be updated regularly. Abstracts are due September 11.

CLIVAR-relevant sessions at 2019 AGU Fall Meeting

The 2019 AGU Fall Meeting will be held from December 9-13 in San Francisco, California. In preparation for the meeting, we have compiled a list of sessions that are relevant to the community and organized by our Panels, Working Groups, and community members. The list of sessions is not intended to be exhaustive but to help digest the collection of the hundreds of sessions and events.
