Subheadline: Unique weather phenomenon causes pilotless helicopter sounds
OSLO — Residents of Norway’s capital may have noticed an unusual sight and sound at nightfall: glowing orbs floating through the sky, escorted by the faint hum of a helicopter. Despite the eerie display, there’s no cause for alarm. Blame it on a rare weather phenomenon.
Each year, as autumn approaches, a particular weather pattern sends pilotless helicopters skyward in Oslo. The phenomenon occurs when a strong temperature gradient and wind conditions cause bouquet balloons to rise into the night sky, carrying with them their attached LED lights and small, electric-powered helicopters.
RNO, the Norwegian Weather Service, confirms the phenomenon, attributing it to the combination of strong nocturnal winds and the light, heated air around the city. "It’s a unique spectacle, and while it might seem unusual, it’s a harmless and fascinating display of nature’s whims," says a spokesperson for RNO.
The event has sparked curiosity and amusement among Oslo residents, who often share their observations on social media. Some have even taken to calling it "Oslo’s annual alien invasion," due to the glowing orbs and their extraterrestrial-like demeanor.
So, if you find yourself looking up at the night sky, watching these mysterious orbs accompanied by a soft helicopter hum, don’t worry. It’s just another quirky aspect of Norway’s captivating weather.
