Short Summary

This study objectively partitioned over 700 historic rainfall events by frontal storm signatures to develop synthetic storm profiles, revealing that frontal storms exhibit distinct temporal characteristics and shapes that significantly depart from standard distributions, which is crucial for hydrologic designs sensitive to temporal loading.

Objective

• To investigate how atmospheric drivers, specifically weather fronts, control the spatiotemporal characteristics of storm events and to develop more realistic synthetic storm profiles based on these frontal signatures for improved urban stormwater infrastructure design.

Study Configuration

• Spatial Scale: A hydrologically uniform climate region of more than 14,000 km², represented by 10 distinct weather stations.
• Temporal Scale: Over 700 historic events were analyzed, focusing on their temporal persistence characteristics and seasonality.

Methodology and Data

• Models used: A dimensionality reduction and intuitive averaging framework, initialized by bootstrap resampling, was used to develop synthetic storm profiles.
• Data sources: Observational data from over 700 historic rainfall events collected from 10 distinct weather stations within the study region.

Main Results

• Fronts exhibit distinctive temporal persistence characteristics, with cold front events showing greater variability than warm front events across all stations.
• Synthetic storm profiles were developed, yielding distinct storm shapes under different air mass regimes.
• The temporal development of frontal storms significantly deviates from the widely-used center-peaking NRCS storm distribution.
• Seasonality plays a confounding role, as summer storms, regardless of front type, display peak rainfall intensities in the first half of their time series, indicative of prevalent convective activity.
• For hydrologic designs where only maximum intensity or static depth is critical, frontal partitioning has a limited role.
• For designs where temporal loading impacts performance, such as nature-based solutions, the secondary effects of frontal storm event shape are consequential.

Contributions

• Objective partitioning of a large dataset of historic rainfall events into distinct frontal storm signatures for a significant geographic region.
• Development of novel synthetic storm profiles that capture the unique temporal shapes associated with different frontal types.
• Demonstration of a significant departure of frontal storm temporal development from conventional design storm distributions (e.g., NRCS).
• Highlighting the critical importance of considering frontal storm event shape for performance-sensitive hydrologic infrastructure designs, particularly nature-based solutions, where temporal loading is a key factor.
