Study Finds Amplified Seasonality in the Amazon Plume Region, Favoring More Extreme Marine and Terrestrial Conditions

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.

Study introduces new model processing technique, shows North Atlantic climate highly predictable 4 August 2020

Study introduces new model processing technique, shows North Atlantic climate highly predictable

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.
