Future projections of wet snow frequency and wet snow load on overhead high voltage conductors over Italy

Wet snow sleeves on overhead power lines can damage infrastructure and cause blackouts. The CLIWAC growth model has been developed, and the WSLD and WSLF indices have been defined to characterize events over the course of the 21st century at multiple intensity levels.

Wet snow sleeves on overhead power lines pose a serious threat to infrastructure as they can cause severe damage. Climatic projections until 2100 with 4 km resolution of wet snow frequency (WSF) and associated loads (WSL) on high-voltage lines have been developed. Additionally, their occurrence probability at different intensity levels has been calculated using Extreme Value Analysis (EVA), with WSLD and WSLF indices defined for this purpose.

 

Based on the Makkonen snow sleeve growth model using hourly weather data, the CLIWAC model has been developed for climatic purposes, applied to daily data from Euro-CORDEX models under RCP8.5 and RCP4.5 configurations. WSF and WSL scenarios indicate decreasing events except at higher altitudes. WSLD and WSLF indicate variations in WSL consistent with EVA, providing the advantage of predicting their evolution beyond outdated return period concepts in climatic instability conditions.
