Climate Clues from One of the Rainiest Places on Earth

by Andrew J. Wight 7 June 20218 March 2022

One of the world’s rainiest places lies off Colombia’s Pacific coast. New field research sheds light on the Chocó low-level jet, a phenomenon responsible for the region’s precipitation.

Landslides Mar the “Pearl of Africa”

by H. Mafaranga 19 April 20212 August 2022

Behind Uganda’s lavish beauty, climate change has taken its toll: Death, destroyed properties, and displaced communities increase as above-normal rainfall floods the country.

Extreme rainfall is more likely to occur in the United States as temperatures rise.

Extreme Rainfall Statistics May Shift as U.S. Climate Warms

by Sarah Stanley 12 April 202118 February 2022

Precipitation data and high-resolution modeling suggest that extreme rainfall events under a changing climate will be shorter, more intense, and more widely spread out.

A Window into the Weather on Titan

by Kate Wheeling 22 March 20218 March 2022

Cassini’s final flybys of Saturn’s largest moon may have captured a temperature drop due to rainfall, one of the first observations of weather changes on Titan.

Rainfall Change with Warming More Consistent than Anticipated

by Alessandra Giannini 26 February 202114 October 2021

Dew point temperature better explains precipitation change with warming than temperature itself, and the relation is more spatially coherent than previously thought.

Finding “Glocal” Solutions to Flooding Problems

by Alka Tripathy-Lang 3 February 202120 May 2022

Scientists call for joint efforts to combine real-time global rainfall data with high-resolution local hydrology to better forecast floods.

A Slippery Slope: Could Climate Change Lead to More Landslides?

by Jane Palmer 23 November 202031 March 2022

Scientists investigate whether warming temperatures and changing rainfall patterns could be triggering more landslides in mountainous areas.

More Clustered Clouds Amplify Tropical Rainfall Extremes

by Sarah Kang 15 October 202014 February 2023

Both satellite observations and model simulations reveal that more aggregated convection amplifies the increase in extreme rainfall events on a year-to-year basis.
