When a Low Pressure Goes Through

There have some intense winter low pressure systems barrelling onto UK shores recently, going by the name of Storm Angus.

Below are some images that paint a picture of what happened to the air and water as this low hit central southern England.

They show how a plunge in air pressure and the associated front will impact wind speed, wind direction, temperature and sea conditions.

Update:

Thanks to Cindy McCafferty, who has written from Wisconsin, USA:

“You might find this interesting. We had 6 tornadoes touch down in about an hour from 11:30 pm to 1:30 am. This tree landed a foot from my daughter’s house. It was an EF2. Before it hit, her two cats were frantically running through the house trying to get away from it. They could sense it.”

As is usually the case, American storms make our UK ones look a bit kindergarten.
