Revisiting the Great Salinity Anomaly of the 1970s

Research supported by the Climate Variability & Predictability (CVP) program challenges long-standing beliefs on what led to the development of the 1970s Great Salinity Anomaly and resulting shutdown of the Labrador Sea deep convection. 

Subantarctic Stratification in Climate Models Controlled by Ocean Circulation 4 November 2020

Subantarctic Stratification in Climate Models Controlled by Ocean Circulation

Climate Variability & Predictability (CVP)-funded researchers find that a common Southern Ocean bias in CMIP5 climate models is due to errors in the simulated ocean circulation.

Improvements in MJO Prediction Skill May Lead to Better Prediction in Meteorological Variables 3 November 2020

Improvements in MJO Prediction Skill May Lead to Better Prediction in Meteorological Variables

Better prediction of the Madden-Julian Oscillation (MJO) can lead to better prediction in related meteorological variables, such as precipitation. However, the relationship between MJO skill and the predictive potential for meteorological variables is complex, as this Climate Variability & Predictability (CVP)-supported study shows.

California-Native Trees Uptake of Acyl Peroxynitrate Keeps Nitrogen Oxides From Re-entering Atmosphere 3 November 2020

California-Native Trees Uptake of Acyl Peroxynitrate Keeps Nitrogen Oxides From Re-entering Atmosphere

Atmospheric Chemistry, Carbon Cycle, & Climate (AC4)-funded researchers determine acyl peroxynitrate, one possible result from nitrogen oxide (NOx) reacting in the atmosphere, can act as a NOx sink rather than a reservoir in rural and remote forested regions.

Evidence of Increasingly Intense Large-Scale Wave Activity During Summertime in the Western North Pacific 3 November 2020

Evidence of Increasingly Intense Large-Scale Wave Activity During Summertime in the Western North Pacific

The large-scale summertime wave pattern over the western North Pacific has increased in intensity since 1950, according to researchers supported by CPO’s Climate Variability and Predictability (CVP) program using NCEP-NCAR reanalysis data.
