• 19/11/2024 - Anurag DIPANKAR: "Global storm resolving simulations in a python framework - progress and challenges"

  

  Anurag DIPANKAR (ETH Zürich)

  The modern exascale computing systems have given the climate and weather modeling community an opportunity for a step change in their simulation capabilities. One expects a grid resolution sufficiently large to resolve the key atmospheric processes provided the machine is properly utilized. However, this is a non-trivial task. Given the complexities at various levels from the hardware to the software (model), the conventional software needs to be redesigned in a way that it fully utilizes the exascale capabilities while keeping it easy to use. The talk will give an overview of the approach we have taken in this direction in EXCLAIM, and brief the progress and challenges we have faced so far.

  Manuela LEHNER (ACINN, University of Innsbruck)

  TEAMx is an international research programme that aims at improving our understanding of transport and exchange processes in the atmosphere over mountainous terrain and at evaluating and improving the representation of these processes in weather and climate models. As part of the TEAMx programme, a one-year long observational campaign is taking place between fall 2024 and fall 2025. Observations are being collected in four target areas along a north-south transect through the Alps from the Alpine foreland to Lake Garda. The presentation will give an overview of TEAMx, its scientific objectives, and the activities taking place during the Observational Campaign.

  Rupert KLEIN (FU Berlin & WPI)

  Colloquium of the research platform MMM, jointly with Meteorological-Geophysical Colloquium

  This presentation will explain by way of examples how data-based machine learning and physics-based mathematical modelling may contribute valuable complementary skills and insights to weather and climate science. Judicious combinations of both promise further progress. There are serious potential pitfalls and caveats, however. The examples involve many-month El Niño prediction, mechanisms for the spin-up of tropical cyclones, and more.

  Petr SACHA (Charles University Prague)

  Website of the group

  Our knowledge of gravity wave impacts ranging from regionality of precipitation to the global evolution of ozone layer is predominantly based on their parameterized effects. In this talk we will constrain the leading order dynamical effects of gravity wave parameterizations in global climate models with gravity wave resolving datasets and demonstrate the importance of two processes that are neglected in current parameterizations (namely the oblique propagation and gravity wave induced turbulence), but play a role in the atmosphere.

• 17/12/2024 - Thomas KRENNERT: "Crowd-Sourced Human Weather- and Impact-Reports in Austria – a crucial support to mitigate extreme weather- and climate- impacts?"

  

  Thomas KRENNERT (Geosphere Austria)

  Governments and civil authorities struggle with mounting socio-economic challenges caused by extreme weather and climate impacts. In the context of real-time warnings and future risk assessments, robust data on weather and climate related hazards and damages are essential. Since 2020, Austria's national weather service, GeoSphere Austria (formerly ZAMG), has compiled a database of About 120,000 human weather and impact reports, facilitated through the web-app wettermelden.at. Since weather stations cannot detect hazards like flooding, wind damage or similar, these impact observations provide a valuable “ground-truth” data source. Utilizing weather- and impact-reports a real time feedback loop between disseminated weather warnings and impact reports
  from voluntary observers is established - an important capability for GeoSphere as a key advisor within the Austrian National Crisis and Disaster Management SKKM. Moreover, these reports contribute to forensic damage assessments following extreme weather events and provide valuable data for climate impact research.
  With the Trusted Spotter Network Austria (TSN), GeoSphere offers a comprehensive training program for voluntary weather enthusiasts. Through this program, fully trained "Trusted Spotters" enhance the accuracy and reliability of their reports.
