Spatial Scale Shapes the Ocean and Atmosphere’s Influence on the Climate
Researchers measured the processes driving heat exchange between the Pacific Ocean and the atmosphere.
Machine Learning Emulation of Atmospheric Radiative Transfer
Using machine learning to represent sub-grid processes in weather and climate models holds promise, but also faces challenges. Incorporating physical knowledge can help.
Severe Storms Expose Ill-Equipped Weather Stations in Southeast Africa
The lack of infrastructure is preventing scientists from robustly reporting meteorological information as well as communicating warnings about hazard-prone areas.
Simulating Surface Impacts of Stratospheric Sudden Warmings
New evaluations of climate model simulations show how the stratosphere polar vortex couples to surface weather.
An Unprecedented View Inside a Hurricane
To improve future tropical cyclone forecasts, researchers sent a remotely operated saildrone into the extreme winds and towering waves around the eye of a category 4 hurricane.
A Lidar’s-Eye View of How Forests Are Faring
Success in Yosemite is driving the wider use of lidar surveys to support forest health and wildfire resilience, study wildlife habitats, and monitor water resources.
Chronicling the Hottest, Coldest, Windiest, and Rainiest Weather
The World Meteorological Organization verifies and documents record-setting temperatures, winds, lightning, and more, offering snapshots of Earth’s extremes and hints about its changing climate.
Corrective Machine Learning for Improving Climate Models
A machine-learned correction enables an efficient coarse-grid global atmosphere model to better track the weather and time-mean precipitation of an expensive fine-grid ‘digital twin’ reference model.
Impact of Assimilating Aeolus Winds on Kelvin Waves
Assimilation of Aeolus winds in the ECMWF analyses and forecasts improves the Kelvin Waves representation and forecasts in the tropical tropopause layer.
