Variations in the amount of precipitation that feeds the Amazon River, ranked as the world’s largest river in terms of annual discharge, can profoundly impact the marine ecosystem in the region where the fresh river water enters the salty ocean (Amazon plume region) and influence the hydroclimate over the tropical Atlantic.
This study is a step towards accurate modeling of the MJO, a challenge that has troubled the weather and climate science community for some time.

The study may have large implications for the climate and weather forecasts made by ocean models in the future.
Climate model projections can be hindered by complexities inherent in the climate system, and difficulty in detecting the part of the forecast that can be accurately predicted (signals) as well as constraining uncertainties (noise). These problems can be hard to fix, as climate model projections cannot be verified until there are observations.
The findings address an important gap in understanding that could help advance prediction capability for U.S. summer to fall precipitation.

The findings have important implications for changes we are likely to see in the 21st century.
Using climate projections to assess climate change risks remains challenging, in part due to the large associated uncertainties, such as those for extreme events.
ESSM supports effort to address climate projection uncertainties through large ensembles Read More »
Today, scientists using multiple human-piloted and autonomous vehicles, buoys, radar, and computer modeling embarked on a six-week scientific campaign off the island of Barbados to investigate how the ocean, atmosphere, and shallow clouds work together to create the weather and climate we live in.

New research, funded by CPO’s Climate Variability and Predictability Program, shows that warming of the Indo-Pacific Ocean is altering rainfall patterns from the tropics to the United States, contributing to declines in rainfall on the United States west and east coasts.
