Polar vortex coming, brace yourselves!
What is a polar vortex?
A polar vortex is a large area of low pressure and cold air that surrounds the North and South Poles. It is a semi-permanent feature of the Earth's climate system and is strongest in the winter months.
How do polar vortexes form?
Polar vortexes form when cold air from the poles sinks towards the ground. This creates a low-pressure area at the surface, which then draws in more cold air from the surrounding areas. The resulting vortex can be thousands of kilometers wide and several kilometers deep.
What are the effects of polar vortexes?
Polar vortexes can have a significant impact on the weather in the mid-latitudes. They can cause cold spells, heavy snowfall, and strong winds.
In some cases, polar vortexes can even lead to extreme weather events, such as ice storms and blizzards.
What is the polar vortex doing now?
The polar vortex is currently over the central United States. It is expected to bring cold weather and snow to the region over the next few days.
The polar vortex is also expected to weaken later this week, which will allow warmer air to move into the central United States.
How can you stay safe during a polar vortex?
If you live in an area that is expected to be affected by a polar vortex, there are a few things you can do to stay safe:
- Stay indoors as much as possible.
- If you must go outside, dress warmly in layers.
- Cover your head and face to protect yourself from the cold.
- Limit your time outdoors.
- Be aware of the signs of hypothermia and frostbite.
