At MET Norway, a small interdisciplinary team – the Sandbox – tries to improve the communication between the meteorologists and their audience. In 2021, we focused on the communication of forecast uncertainty. The Sandbox created, with input from internal and external experts, solutions for applying linguistic and visual tools for forecasters to communicate about uncertainty. In the article, we share our experiences and lessons learned.

This study presents estimates of the maximum temperature in Bangladesh for the 21st century for the pre-monsoon season (March–May), the hottest season in Bangladesh. The maximum temperature is important as indicator of the frequency and severity of heatwaves. Several emission scenarios were considered assuming different developments in the emission of greenhouse gases. Results show that there will likely be a heating of at least 1 to 2 degrees Celsius.

We present results from the project Impacts of extreme weather events on infrastructure in Norway. Our analyses document an increase in frequency and intensity of e.g. precipitation and wind during the last decades, and that these observed changes will continue throughout the 21st century. We could show that ≥ 27 % of main roads and 31 % of railroads are exposed to rockfall and avalanches. Pro-actively facing such risks will increase resilience and cost-efficiency of the transport infrastructure.
