Assessing Downburst Kinematics Using Video Footage Analysis
AtmosphereMeasurements of downburst outflows using standard meteorological instruments (e.g., anemometers) are rare due to their transient and localized nature. However, video recordings of such events are becoming more frequent.

The Predictability of the Southern England 23 October 2022 Severe Downbursts
Atmospheric Science LettersAccurate prediction of damaging straight‐line wind events from convective storms relies heavily on storm morphology and nowcasting. Utilising the Microburst Wind Potential Index in ensemble forecasts we examine the predictability of its different ...

Full-Cloud Numerical Simulation of a Translating Isolated Thunderstorm Producing a Wet Downburst
AtmosphereA real downburst event that occurred in the city of Genoa, Italy, on 14 August 2018, is simulated using the full-cloud model CM1. The initiation of the thunderstorm cell is triggered through the warm bubble technique, which allows simulating the whole ...
