The predictor defines the sting jet as a small area of very strong winds, which can reach speeds of up to 100 miles per hour or more, forming in the powerful weather system that crosses the UK. Can give
Although strong winds usually blow for short periods of time, perhaps up to four hours, and within a small area of up to 30 miles, the Met Office said the trend could lead to “significant damage and danger to life.”
The so-called Great Storm in October 1987, which killed 18 people, is the most famous example of a sting jet, the forecaster said.
The Met Office said wind speeds reached 115 miles per hour and an estimated 15 million trees fell.

Explaining how these jets are made, the forecaster said that the weather separates the hot and cold air areas and their interaction creates and develops wet and windy weather.
Near the climatic fronts are more concentrated streams of hot and cold air, known as conveyor belts – with hot conveyors rising and cold conveyors falling.
The Met Office said they “wrap around the low-pressure area and help prepare the system by providing warm air and moisture.”
He added: “The cold conveyor carries its cool air from a high place in the air and a large amount of cool air. Sometimes it is helped by rain and snow when they fall into it and evaporate.
This change from gas to liquid requires heat, which is removed from the conveyor and further cooled. Now we have an even cooler wind blowing with the conveyor, speeding up like a roller coaster taking the first drop.
“When this wind reaches the surface, it can often produce much stronger gusts than would otherwise be caused by a storm. However, after a few hours, the cold conveyor catches itself and eats the sting jet. The time and area of potential damage is very small. “
The Met Office said that during the Great Storm of 1987, the worst damage occurred in the south-east of England, with gusts of 70 knots or more recorded for three or four hours straight.
Falling trees on roads and railway lines left thousands of homes without power for more than 24 hours and disrupted transport.
The Met Office also recalled how several small boats were destroyed or blown up, a plane was blown up in Dover and a Channel Ferry was blown up on the shore near Folkestone.
Even the oldest people in the worst-affected areas at the time “could not remember such strong winds or such a massive catastrophe,” the forecaster said.
Dr. Peter Anis, a meteorologist at the University of Reading, said a “strong jet stream” could act as a production line for hurricanes, creating a new storm every two days.
He added: “Eunice looks like it might be able to produce a ‘sting jet’, a narrow, concentrated region of extremely strong winds that engulfs a large area of strong winds and lasts only a few hours.” ۔
“Such incidents are rare, but the ‘Great Hurricane’ of 1987 almost certainly produced sting jets, and some of the more damaging wind storms since then have shown this pattern.”
He said two red warnings for wind in the same winter are very unusual for the UK, as it is more common to meet once every two or three years.
