What is a sting jet weather?

A sting jet is a small area of very intense winds (often 100mph or more) that can sometimes form in powerful weather systems crossing the UK. Relative to the size of the storm, the sting jet is narrow, often 30 miles across, and only lasts 3 to 4 hours. The Great Storm of 1987 was a perfect example of this.

Is a meteorological phenomenon which has been postulated to cause this cloud hooked like a scorpion’s tail gives the wind region its name the sting jet?

This cloud, hooked like a scorpion’s tail, gives the wind region its name the “sting jet”. The evaporative cooling leading to the air within the jet becoming denser, leading to an acceleration of the downward flow towards the tip of the cloud head when it begins to hook around the cyclone centre.

Why do extratropical cyclones move from west to east?

The wind flow around an extratropical cyclone is counterclockwise in the northern hemisphere, and clockwise in the southern hemisphere, due to the Coriolis effect (this manner of rotation is generally referred to as cyclonic).

What is a Jet string?

Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets, including Earth. On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east). Their paths typically have a meandering shape.

What kind of winds do Sting jets cause?

A sting jet is a meteorological phenomenon which has been postulated to cause some of the most damaging winds in extratropical cyclones, developing according to the Shapiro-Keyser model of oceanic cyclones.

How long does a sting jet storm last?

Relative to the size of the storm, the sting jet is narrow, often 30 miles across, and only lasts 3 to 4 hours. Regardless, with gusts of wind exceeding 100 mph there is clearly still the risk of damage. The Great Storm of 1987 was a perfect example of this.

What was the sting jet in the Great Storm of 1987?

The Great Storm of 1987. A sting jet is a meteorological phenomenon which has been postulated to cause some of the most damaging winds in extratropical cyclones, developing according to the Shapiro-Keyser model of oceanic cyclones.

How did the sting jet get its name?

This cloud, hooked like a scorpion’s tail, gives the wind region its name the “sting jet”. It is thought that a zone of strong winds, originating from within the mid-tropospheric cloud head of an explosively deepening depression, are enhanced further as the ” jet ” descends, drying out and evaporating a clear path through snow and ice particles.
