This visualization shows a CESM1 model comparison between a present day (1990) and a future (2090) simulation using a business-as-usual or high emissions scenario, called RCP8.5. Clouds represent six-hourly time steps of total water vapor for one year. Technically speaking, this is the CESM1 model variable, TMQ, defined as the total precipitable water (vertically integrated)…

CESM Decadal Prediction Large Ensemble
Forecasting decadal trends in the North Atlantic and Arctic Decadal climate predictions exhibit skill in retrospective predictions of observed multi-year trends in sea surface temperature (SST) and sea ice fraction in the high latitudes of the Northern Hemisphere, particularly in the Atlantic sector. The skill is largely attributable to realistic ocean initialization, but external radiative…
