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 each other. Although the events are not predictable more ...[Read More]
When it is dark over Ny Ålesund, Svalbard, a bright green laser beam can be seen quite often, shooting from the AWIPEV Arctic Research Base observatory towards the sky. This beam belongs to “KARLi” the Koldewey Aerosol Raman Lidar, run by the Alfred Wegener Institute for more than 25 years, which contributes to long-term, atmospheric aerosol measurement records. With this system ...[Read More]
Happy New Year!! 2020 has been a pretty relentless and turbulent year – and a lot has happened. Here at EGU headquarters (currently spread across our staff’s several homes) we all know how much we owe to you, our members, followers and friends, this year, through all the highs and the lows. We honestly could not have made it through without our wonderful community – and yo ...[Read More]
Taken shortly after our departure from Ny-Ålesund after our first “Lost Meteorites” field trial in Greenland testing new equipment that can be used to discover ‘missing’ iron meteorites in Antarctica, the return flight gave incredible views of the surrounding landscape. This photo was taken looking down to the icy waters of Kongsfjorden on the west coast of Svalbard and the ...[Read More]
Moisture coming from the ground is freezing at the entrances of small ground pockets, shaping wonderful natural ice crystals, during a very cold and dry winter in Poland in 2019. Description by Katarzyna Walczak, after the description on imaggeo.egu.eu. Imaggeo is the EGU’s online open access geosciences image repository. All geoscientists (and others) can submit their photographs and video ...[Read More]
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 December, the Divisions we are featuring are: Cryospheric Sciences (CR), Climate: Past, Present & Future (CL) and Nonlinear Processes in Geoscience (NP). They are served by the journals: Geoscientif ...[Read More]
The coating by the ice and the icicles are created through the interplay of wave action and the simultaneous freezing of the water around the exposed tree roots. The reason for the exposed tree roots is increased bank erosion due to a rather unusual circumstance. The combination of the lake not yet being frozen in early winter, and strong winter storms, make it very easy for the waves to erode the ...[Read More]
The European Research Council (ERC) is a leading European funding body supporting frontier research, investigator-driven, across all fields of science.The ERC offers various different funding opportunities with grants budgets of €1.5 to €3.5 million for individual scientists with the sole criterion for selection being scientific excellence. In October, the EGU hosted a webinar that highlighted som ...[Read More]
Photo of the air chemistry observatory of the German Neumayer III Antarctic station during Polar Day 2017. Located in a clean air sector south of the station, the observatory’s main purpose is to record continuous, year-round data records of relevant particulate and gaseous trace components of the troposphere. As one of only few stations located in the very clean troposphere of Antarctica, i ...[Read More]
Hello Stéphane and Tommaso, thank you for speaking with us today – could you briefly introduce yourselves? Stéphane Vannitsem Okay, so my name is Stéphane Vannitsem, and I am a researcher at the Royal Meteorological Institute of Belgium, in Brussels, and I’ve recently become head of the Meteorological and Climatological Information Service. I’m also a lecturer at the Free Univers ...[Read More]
