The stratospheric potential vorticity field on February 10, 2018. The Stratospheric Polar Vortex is about to split in two, and the weakening of the vortex was followed around two weeks later by a severe cold air outbreak over Europe known as the Beast from the East. Data from ERA-Interim reanalysis […]

November 22, 2020 On November 22, 2020, Cyclone Gati became the strongest storm to hit Somalia since satellite records began five decades ago. Gati made landfall with maximum sustained winds of 170 kilometers (105 miles) per hour, a category 2 storm on the Saffir-Simpson scale. The storm brought more than […]

Storms gathered at the south pole of Jupiter, as imaged by the Juno probe. Credit: NASA/JPL-Caltech/SwRI/ASI/INAF/JIRAM At the south pole of Jupiter lurks a striking sight—even for a gas giant planet covered in colorful bands that sports a red spot larger than the earth. Down near the south pole of the planet, […]

A blazing sunset lights up the evening sky. Credit: NOAA Four years of research confidently narrows range of 1.5°C-4.5°C down to 2.3°C-3.9°C. The most advanced and comprehensive analysis of climate sensitivity yet undertaken has revealed with more confidence than ever before how sensitive the Earth’s climate is to carbon dioxide. […]

Two satellite images show vegetation change from fog in two areas of the Namib desert. The left image shows the areas during periods of lower fog; the right image shows the areas during periods of higher fog. Greener areas inside the squares indicate vegetation greening.

(Click HERE for full view.) Artist’s impression of multi-wavelength emission above a thunderstorm based on data from ASIM. The high electric field associated with lightning (light blue) generates a terrestrial gamma-ray flash (magenta). The resulting electromagnetic pulse causes an elve, or expanding ring of ultraviolet emission (red and white). Credit: […]
