+ There are many moments during the vineyard cycle where climate plays a key role. For instance, spring is a critical season for frosts, as just one night of frost can damage the whole production. On the producer’s side, there are some management actions that can be applied to reduce damages in the short-medium term, such as late pruning to delay the bud-break (Persico et al. 2023). Wine companies may also consider paying insurance to receive compensation in the case of frost damage affecting grape production. In the longer term, wineries may consider investing in a frost prevention system or choosing grape varieties with delayed bud-break that are better adapted to climate change. Having information about the changes in the frequency and intensity of spring frosts in the future can help wineries to decide on the most suitable adaptation actions. +
++ Another challenge for Spanish agriculture, especially in the Mediterranean region, are droughts, which exacerbate during the summer period. As long as there is water available in the reservoirs, wine producers with irrigation systems in place may be able to irrigate the vines. However, in the case of water restrictions, wineries have to assume a lower production or buy grapes from external farmers. A useful indicator for the monitoring of agricultural drought is the Standardised Precipitation and Evapotranspiration Index (SPEI), which assesses water availability comparing the balance between precipitation and potential evapotranspiration. Another indicator such as the average maximum temperature for the months of June-July-August is also useful to identify heat stress hotspots. +
++ This not only offers the Spanish wine sector the opportunity to have quick access to climate data on the past, present and future, but also the possibility of defining their own climate-related indicators. +
++ Such indicators include the average maximum temperature in summer, spring frost, or SPEI, which can be calculated as the climate model runs. This allows wineries to have regularly updated information on the risks of spring frost, heatwaves, and droughts that may affect their vineyards in the long-term future. Additionally, the digital twin offers a unified climate information source for those producers that own farms not only in the Spanish territory but also in other world regions suitable for grape and wine production, like California or South America to name a few. +
++ These tailored indicators allow the energy sector to more efficiently ensure the security of energy supply, price and power grid stability; obtain reliable data on how energy systems and turbine structural integrity can cope with the effects of extreme events; and have insights into future changes in climate variability to plan and manage the design of energy systems and the impact on energy demand and prices. +
++ Using storyline simulations with high spatio-temporal resolution, we have been able to examine the impacts of this event and also how it would manifest in a +2 K warmer world. We have investigated four different locations (Alicante, Girona, Ibiza and Valencia) that experienced precipitation extremes and examined if these would intensify in a warmer climate. While a big spatial variability is seen in total rainfall, areas around Valencia and Alicante, that already experienced record rainfall, show increases of around 100mm. Combined with dryer soils due to Mediterranean warming, this type of increase in extreme precipitation, could greatly increase the likelihood of flash flooding. +
++ This information may be of interest for the insurance and (re)insurance sectors, since they have signaled flooding as a big issue, causing flood insurance premiums to rise as these events are becoming more common. Having access to climate data that could be coupled to their in-house catastrophe models may be important for this sector. +
++ Likewise, better modeling the effect of extreme rainfall events is of interest for the ecological scientific community interested in the impacts of high-impact storms on marine ecosystems (e.g. regression of beaches and health impacts due to the proliferation of microalgae). +
