Earth Expeditions: In Dust and Clouds Over Africa, Scientists Find Clues to How Hurricanes Form

05.24.2023
When the dust that wafts off the Sahel and Sahara regions of Africa mixes with tropical clouds, it creates what’s known as a rainy “disturbance” in the eastern Atlantic. These disturbances are hurricanes in their youngest form, and as they travel across the ocean, they can either dissipate or grow into powerful storms.

To study these infant storms, a group of NASA scientists in September 2022 spent a month flying off the northwestern coast of Africa aboard NASA’s DC-8 research plane. Each day, the team took off from Cabo Verde, an island nation off the west coast of Africa, logging roughly 100 hours altogether. The mission, known as the Convective Processes Experiment – Cabo Verde (CPEX-CV) released its data publicly on April 1.

Overview

The Atmospheric Chemistry and Dynamics Laboratory advances understanding of changes in the Earth’s radiation balance, air quality, and the ozone layer that result from changes in atmospheric composition. Using a combination of satellite data, atmospheric models, and in situ observations, the Laboratory strives to understand:
• the factors that control stratospheric ozone and trace gases that influence ozone,
• the natural processes and human activity that impact the composition of Earth's troposphere, and
• the impact of climate change on future concentrations of stratospheric ozone and tropospheric gases.

For further information, data, research, and other resources, see Atmospheric Chemistry and Dynamics Projects.
