Meteorological services are undergoing a transformation from providing forecasts of atmospheric conditions towards delivering actionable information on possible impacts and risks. Drawing on examples from the RiskLab at GeoSphere Austria, this lecture introduces key concepts of risk science and demonstrates how hazard information can be combined with exposure and vulnerability data to support risk-informed decisions. The talk reflects on current developments in impact-based forecasting and climate (risk) services and discusses future challenges and opportunities for the meteorological community.

The moist bias in the upper troposphere and lower stratosphere (UTLS) is a well-known deficiency in NWP and climate models that can compromise forecasts of the atmospheric circulation. Using a multi-month European radiosonde dataset in a tropopause-relative framework, stratospheric radiosonde humidity assimilation is shown to reduce the UTLS moisture bias year-round and also improves the temperature and wind fields across the tropopause. Validation against independent NAWDIC airborne lidar observations confirms a substantially reduced moisture bias. The findings underscore the need for improved and enhanced humidity measurements in our observing system.

We are going to look into the world of large hail. Why some storms produce small hail and the others can produce giants that measure more than 10 cm across? How do we keep the records of the large hail and why aren't official weather station records enough? Are there ways how to forecast and nowcast the hail size reliably? What determines the damage potential of hail besides its size? And what can we say about the future of destructive hailstorms in Europe?
