Downburst (Bouře 🌪️)

Downburst označuje v meteorologii extrémně silný sestupný konvektivní proud, který v přízemní vrstvě vytváří silný ničivý vítr vanoucí z bodového zdroje radiálně, tj. přímočaře všemi směry od středu roztékání v přízemní vrstvě. Škody způsobené downbursty vedou někdy k záměně s tornádem, mají však odlišnou povahu. Zatímco v případě tornáda vítr o vysoké rychlosti ob...

Dies war vermutlich ein Teil der Wetterdynamik, die diese Windhose ausgelöst hat.
Nur wenige Sekunden später wütete ein Downburst in Saarbrücken.

Derecho-Induced Skyscraper Damage

Derechos are short-lived, intense wind storms sometimes associated with thunderstorms. Last spring, such a storm passed through Houston, leaving downtown skyscrapers with more damage than a hurricane with comparable wind speeds. Now researchers believe they know why a derecho’s 40 meter per second winds can badly damage buildings built to withstand 67 meter per second hurricane winds.

In surveying the damage to Houston’s skyscrapers, the team noted that broken windows were concentrated in areas that faced other tall buildings. In a wind facility, the team explored how skyscrapers interfered with each other, based on their separation difference. They looked both at conditions that mimicked a hurricane’s winds as well as the downbursts — strong downward wind bursts — that are found in derechos.

The researchers found that downbursts in between nearby buildings caused extremely strong suction forces along a building’s face — even compared to the forces seen with higher hurricane-force winds. Currently, these buildings are designed for hurricane-like conditions, but the team suggests that — at least in some regions — designers will need to take into account how downburst wind patterns affect a skyscraper, too.

Downburst (Storm 🌪️)

In meteorology, a downburst is a strong downward and outward gushing wind system that emanates from a point source above and blows radially, that is, in straight lines in all directions from the area of impact at surface level. It originates under deep, moist convective conditions like cumulus congestus or cumulonimbus. Capable of producing damaging winds, it may sometimes be confused with a tornado, where...

Downburst - Wikipedia

Il #3settembre Roma è stata colpita da un evento meteorologico particolarmente intenso, un #downburst, una perturbazione rapidissima con piogge torrenziali e raffiche di vento discendenti fino a 90 km/h. In pochi minuti sono caduti oltre 60 mm di pioggia in un'ora nel centro storico della città, l'equivalente di un intero mese autunnale!

ℹ️⛈️🌬️Heute vor 8 Jahren am 24.06.2016:
In der Nacht zog eine Gewitterfront mit #Downburst (Fallböen) v.a. über die mecklenburgische Küstenregion. In #Boltenhagen gab es extreme #Orkanböen bis 156 km/h!! Dort Schäden an Gebäuden + alle Zufahrtsstraßen durch Bäume blockiert.
