What Makes the Biggest Cycle in Tropical Weather Tick?

by Mark Zastrow 21 June 201713 February 2023

The Madden-Julian Oscillation drives storms across the Indian and Pacific oceans every 30 to 60 days. New research suggests that clouds absorbing and reemitting radiative energy play a key role.

How Do Tropical Forests Slow Knickpoints in Rivers?

by W. Yan 1 July 201627 April 2022

Using Puerto Rico's Luquillo Mountains as a case study, scientists use the region's geological history to study how knickpoints—areas where there's a sharp change in the river's slope—move over time.
