When storms slow down: urban effects on rainfall accumulation and flood hazard.
Article in npj natural hazards, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Changes to convective storm motion over urban areas may have important implications on rainfall accumulation and flood risk. Here, we investigate speed changes in storms passing over cities using weather radar data and convection-permitting numerical simulations. The observational analysis consists of tracking individual rain cells across eight cities and comparing movement speeds near the cities relative to a control upwind region. Second, we simulate ten heavy rainfall events crossing Indianapolis, Indiana, and compare cloud-layer horizontal wind speeds from two scenarios: one with and one without the city. We find that the speed of the observed rain cells decreases over and downwind of five urban areas, and seven simulations reveal dampened cloud-layer wind speeds over Indianapolis. Stronger updrafts induce horizontal wind slowing, driven by the warm urban surface. We conclude that rainfall intensification is the primary driver of enhanced urban rainfall accumulation, yet storm slowing contributes to more frequent and stronger enhancements.
