Projections of tropical cyclones and rainfall in the African Sahel could be improved with better understanding and representation of African easterly waves in models

Accurately simulating AEWs is critical to predicting Atlantic tropical cyclones and hurricanes, but new research supported by the Climate Variability and Predictability program, and accepted for publication in the Journal of Climate, demonstrates several shortcomings in CMIP5 models preventing accurate representation of AEWs.

Progress in observing and predicting ENSO

In January 2014, NOAA and the Japanese Agency for Marine-Earth Science and Technology (JAMSTEC), in collaboration with the Ocean Observations Panel for Climate (OOPC), convened a review of the Tropical Pacific Observing System (TPOS) through a workshop and associated white papers.

Contribution of sea surface carbon pool to organic matter enrichment in sea spray aerosol

Research funded by CPO’s Atmospheric Chemistry, Carbon Cycle, and Climate (AC4) program was published in Nature Geosciences.  The article assesses the relationship between the organic carbon content of sea water and freshly emitted sea spray aerosol in the North Atlantic as well as the coastal waters of California.
