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.

Atmospheric dynamics drive most interannual U.S. droughts over the last millennium

Analysis of the last millennium reanalysis climate reconstruction shows a clear connection between Southwest drought and La Niña sea-surface temperature patterns. However, this pattern only explains a small part of the variability associated with past U.S. droughts.

Two new indicators help track climate change

Researchers highlight the significance of examining trends in large-scale weather patterns using these new indicators since they reflect near surface conditions, are key drivers of extra-tropical weather, and are important regulators of human comfort for approximately half of the world’s population.
