Meteorology is lacking a deep understanding of the widely observed phenomenon of preferred thunderstorm intensification at the edges of mountain chains. Also high-resolution models struggle with initiation, intensification and quasi-stationarity of thunderstorms, being a frequent topic close to or at mountains. High-resolution data (both in space, time and complementarity) is needed to resolve partially conflicting theories and to provide both reference and experimental input for high-resolution models. This conference contribution provides an overview of the goals, timeline and partners of the TIM Severe Storms Field Campaign and its focus on effects caused by complex topography. All TIM partners are required to follow a responsible conduct strategy for the entire field campaign. This includes minimising the environmental footprint by maximising green mobility and thorough CO2-sensitive planning, and giving preference to local suppliers and small businesses. TIM is aiming not only to collect measurement data but also pre- and post-event data including damage assessment and social studies.
