Researchers use computer simulations to show that extreme weather phenomena can be controlled and modified by making small adjustments to variables in the weather system. The study’s findings promise multiple future applications where weather events can be better controlled, including the effects of climate change.
Jakub Stepanovic, a mixed-media artist who focuses on mapping and the environment and Kelly Stanford, a digital artist and science communicator, have been selected for a residency at the next European Geosciences Union (EGU) General Assembly 23–27 May 2022. Our previous Artist in Residence, Elena Popova, will unfortunately no longer be able to join us in 2022.
The Union is gravely concerned by the recent invasion of Ukraine, and hopes for a swift and peaceful resolution, achieved through co-operation and negotiation, rather than aggression.
Professor Chris King, chair of EGU’s Education Committee and a champion of geoscience education, died late last week.
Members of the media, public information officers and science bloggers are now invited to register for the meeting free of charge. EGU22 will be held from 23-27 May, 2022 both in-person (Vienna, Austria) and online.
Depending on temperature and chemical makeup, certain aerosols can be highly viscous or glassy, with atmospheric implications. We have therefore implemented two major upgrades to the predictive viscosity model AIOMFAC-VISC. First, we created a new viscosity model for aqueous electrolyte solutions containing an arbitrary number of ion species. Second, we integrated the electrolyte model within the existing AIOMFAC-VISC framework to enable viscosity predictions for organic–inorganic mixtures.
The Asian monsoon anticyclone is the key contributor to the global annual maximum in lower stratospheric water vapour. We investigate the impact of deep convection on the lower stratospheric water using a unique set of observations aboard the high-altitude M55-Geophysica aircraft deployed in Nepal in summer 2017 within the EU StratoClim project. We find that convective plumes of wet air can persist within the Asian anticyclone for weeks, thereby enhancing the occurrence of high-level clouds.
A glacial–interglacial methane-fuelled redistribution of reactive phosphorus between the oceanic and sedimentary phosphorus reservoirs can occur in the ocean when falling sea level lowers the pressure on the seafloor, destabilizes methane hydrates, and triggers the dissolution of P-bearing iron oxides. The mass of phosphate potentially mobilizable from the sediment is similar to the size of the current oceanic reservoir. Hence, this process may play a major role in the marine phosphorus cycle.
Russia has invaded Ukraine. We have been reading and watching in the news how some pieces of high-tech equipment and weapons are being determinant for Ukraine to push back Russia’s invasion. Guided missiles, drones or new generation satellites heavily relie on rare-earth elements for development and production. The aggressor and the invaded country crave for weapons and military equipment to wage war on each other. Lethal and efficient weapons are about having high-qualified engineers and…minerals. Minerals from which many critical …
Why is a fork actually called fork? And why are volcanoes actually called volcanoes? While I do not have any reply for the first question, I have one for the second… and with a quite interesting story. The Earth currently has around 1350 potentially active volcanoes, aside from the volcanoes along the spreading centres (USGS faq); all of them are named after a single volcano, called Vulcano. Vulcano Vulcano is an island of the Aeolian archipelago, located in the Mediterranean …
Have you ever wondered what the voice of a glacier sounds like? Well, listen here! And if you want to know how the glacier makes these sounds, then let’s take a walk on the ice side… Close your eyes and think of the time you were in the middle of the mountains. On a snow plain, a glacier or a frozen lake; just you. You hear your footsteps in the snow, crunching ice. The wind blows through your hood. And …
