In a cosmic twist, geoscientists led by Victor Trees discovered a surprising link between solar eclipses and cloud dynamics, revealing new climate system knowledge. The Communications Earth & Environment study examines the disappearance of clouds, especially shallower cumulus clouds, during an eclipse, which only occurs when the moon crosses in front of the sun.
The team used an enhanced recovery mechanism to measure satellites during eclipses. They found an exceptional change in cumulus cloud composition using data from three African eclipses (2005–2016). Just 15% of the sun’s area covered by the moon was enough to evaporate these clouds on a huge scale, and they resurfaced after the spectacle.
The researchers used DALES cloud modeling software to explain the occurrence. The DALES simulations demonstrated that when sunlight is blocked, the Earth’s surface cools, suppressing warm air updrafts that carry moisture and forming cumulus clouds.
This cloud-dissipating impact was not seen above the ocean because seawater cools too slowly to affect cumulus clouds. The implication stresses clouds’ non-static nature and concerns their role in weather adjustment.
Reading noted that a solar eclipse, even partial, can impact cloud behavior illuminate climate mitigation techniques, one of which could manipulate clouds to affect global warming. Scientists want to delve into the mysteries of the moon, sun, and clouds to understand their impact on Earth’s climatic systems.
