Short Summary

This study investigates how urban areas differentially modulate precipitation intensity, revealing that cities generally increase light precipitation frequency while mitigating extreme precipitation magnitude. These effects, particularly for heavier precipitation, tend to shift to downwind rural areas.

Objective

• To understand whether and how urban effects on hydrometeorology vary with different precipitation intensities.

Study Configuration

• Spatial Scale: Global, focusing on large cities and their upwind/downwind rural counterparts.
• Temporal Scale: Not explicitly stated, but implies a climatological analysis of precipitation event frequencies and magnitudes.

Methodology and Data

• Models used: Weather simulations with a real atmosphere and idealized land surface configuration.
• Data sources: Global satellite-based observations.

Main Results

• 70.1% of large cities experience an increased frequency of light precipitation.
• 69.9% of large cities exhibit a milder magnitude of extreme precipitation compared to their rural surroundings.
• Light precipitation event frequency is enhanced within cities.
• For increasing precipitation intensity, especially for heavy precipitation (>20 mm) frequency and extreme precipitation indices, the enhancements shift to downwind rural areas.
• Weather simulations confirm that urban surfaces lead to more areas of low precipitation intensity but a milder maximum precipitation intensity.

Contributions

• Demonstrates a contrasting influence of cities on light versus extreme precipitation, highlighting an underappreciated role of urbanization in potentially improving local climate conditions.
• Provides global observational evidence complemented by weather simulations to explain urban-induced precipitation modifications across different intensities.
