Preprint under review for NHESS

Short summary

We evaluate fully data- and model-driven predictions of avalanche danger in Switzerland and compare them with human-made avalanche forecasts as a benchmark. We show that model predictions perform similarly to human forecasts calling for a systematic integration of forecast chains into the forecasting process.

Droughts and Media: when and what do the newspapers talk about the droughts in England?

Short summary

This study explores the timing and content of media coverage (i.e., newspaper articles) of droughts in England. We found that media coverage generally coincides with meteorological drought, but the inverse case did not always generate media coverage. Dominant topics include the water deficiency and weather forecasts, but also the mismanagement of water companies and hosepipe bans, highlighting current challenges in water management practices in England.

How is avalanche danger described in textual descriptions in avalanche forecasts in Switzerland? Consistency between forecasters and avalanche danger

Short summary

How is avalanche danger described in public avalanche forecasts? We analyzed 6000 textual descriptions of avalanche danger in Switzerland, taking the perspective of the forecaster. Avalanche danger was described rather consistently, although the results highlight the difficulty of communicating conditions that are neither rare nor frequent, neither small nor large. The study may help to refine the ways in which avalanche danger could be communicated to the public.

Spatial consistency and bias in avalanche forecasts – a case study in the European Alps

Short summary

In 1993, the European Avalanche Warning Services agreed upon a common danger scale to describe the regional avalanche hazard: the European Avalanche Danger Scale. Using published avalanche forecasts, we explored whether forecasters use the scale consistently. We noted differences in the use of the danger levels, some of which could be linked to the size of the regions a regional danger level is issued for. We recommend further harmonizing the avalanche forecast products in the Alps.

Potential slab avalanche release area identification from estimated winter terrain: a multi-scale, fuzzy logic approach

Short summary

Avalanche hazard assessment requires a very precise estimation of the potential starting zone, which nowadays still depends, to a large extent, on expert judgement of avalanches. Therefore, a new algorithm for automated identification of potential avalanche release areas was developed. Potential avalanche release areas can be defined for varying snow accumulation scenarios, improving the automated estimation of release areas, in particular for frequent avalanches.
