Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we will be putting the journals that publish science from those Divisions at the top of the Highlights roundup. For January, the Divisions we are featuring are: Atmospheric Sciences (CR), and Earth and Space Science Informatics (ESSI). They are served by the journals: …[Read More]
120 years ago in 1901, Swedish meteorologist Nils Ekholm used the term ‘greenhouse’ to describe the heating effect that a planet’s atmosphere has on the surface temperature of the planet, the first time that this now much-used and abused metaphor was published. He wrote: “The atmosphere plays a very important part of a double character …[Read More]
In the midst of summer when the sun does not set at high latitudes one can sometimes catch a glimpse of the mesosphere shortly after sunset or before sunrise. These thin veils, known as noctilucent clouds, are the highest known cloud-like structures forming at about 80km above the surface. At this height, they are still …[Read More]
Cyclone Idai, which was labelled by the UN as possibly the worst climate calamity to ever hit the Southern Hemisphere, pounded Beira, Mozambique, in March 2019. The European Space Agency images revealed that a huge new inland ´lake´ measuring about 80 miles by 15 miles, an area the size of the European state of Luxembourg, …[Read More]
The indigenous name of the 3405 meter high Fitz Roy mountain in Patagonia, on the border between Argentina and Chile, is frequently translated as “smoking mountain”. This photo may visually explain an origin of this name. On the day the photo was taken, vortices downwind of the peak drew warmer, humid air from below, forming …[Read More]

Like all people, geoscientists can sometimes forget the importance of language. How scientists use language is important because it not only allows us to communicate effectively with different groups, from policymakers to concerned citizens and other researchers, but it can also influence how people respond on an emotional or personal level. The way we use …[Read More]
The image captures an atmospheric extreme event, a so-called sudden stratospheric warming (SSW) that occurred on Feb. 12, 2018. It is visualized through potential vorticity above the North Pole at the 10hPa level (~30km) above the Earth’s surface and consists of a split of the winter polar vortex into two separate vortices that interact with …[Read More]
