New Insights into Uncertainties About Earth’s Rising Temperature

by Sarah Stanley 30 October 2020

A comparison of climate models finds that much of the variation in their predictions of global warming arises from differences in how they simulate the response of convective processes to warming.

More Clustered Clouds Amplify Tropical Rainfall Extremes

by Sarah Kang 15 October 202015 October 2020

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

The Tropical Atmosphere’s Balancing Act

by E. Underwood 5 June 2019

A new study finds that the tropical atmosphere maintains radiative-convective equilibrium as a whole, but not at smaller scales.

Precipitation in the Tropics: A New View

by Terri Cook 10 April 2019

The first study to simultaneously investigate precipitation and cloud structures in tropical weather systems concludes observation systems significantly overestimate the height of raining clouds.

What Makes the Biggest Cycle in Tropical Weather Tick?

by Mark Zastrow 21 June 201721 June 2017

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 Sea Surface Temperatures Affect an Atmospheric Phenomenon

by S. Hall 23 August 2016

New research sheds light on the complex interplay between the atmosphere and the ocean and how both affect the Madden-Julian Oscillation.

Climate Change Influences the Dynamics Behind Tropical Cyclones

by L. Strelich 27 April 201627 April 2016

A new model reveals how cumulus convection, humidity, and tropical circulations interact as global temperatures rise.

Radar Study Examines Pulsing Tropical Climate

by David Shultz 22 February 201622 February 2016

In the Madden-Julian Oscillation, shear forces caused by air layers slipping and sliding near the equator play a critical role in forming enormous thunderstorms and monsoons.
