Short Summary

This study develops a detailed climatology of precipitation and temperature time series for storms producing heavy rainfall across the Greater Alpine Region, highlighting systematic variations in storm characteristics with duration and geography.

Objective

• Characterize the behavior of storms generating heavy precipitation at sub-hourly to daily scales across the Greater Alpine Region

Study Configuration

• Spatial Scale: The study focuses on the Greater Alpine Region, a complex terrain characterized by diverse geography and climate conditions.
• Temporal Scale: Storms are analyzed at durations ranging from 10 minutes to 24 hours.

Methodology and Data

• Models used: Not specified in the abstract
• Data sources: High-resolution data set from ∼400 climate stations with 15–44 years of records

Main Results

• Storm characteristics vary systematically with both duration and geography, with distinct patterns emerging at sub-hourly, daily, and multi-hour scales.
• At sub-hourly scales, short-lived storms with front-loaded temporal profiles dominate in lowland regions.
• At daily scales, deeper storms with more symmetric temporal profiles are associated with higher intensities in the inner Alps.

Contributions

• This study provides a new climatology of storm behavior in complex terrain, informing precipitation modeling, climate impact assessments, and hydro-geomorphological studies.
