The feature at the centre of this image is possibly a microburst, so what is a microburst?
A microburst is a small, very intense downdraft that descends to the ground resulting in a strong wind divergence.
The size of the event is typically less than 4 kilometers across. Microbursts are capable of producing winds of more than 100 mph causing significant damage. The life span of a microburst is around 5-15 minutes. There are wet microbursts and dry microbursts.
When rain falls below cloud base or is mixed with dry air, it begins to evaporate and this evaporation process cools the air. The cool air descends and accelerates as it approaches the ground. When the cool air approaches the ground, it spreads out in all directions and this divergence of the wind is the signature of the microburst. In humid climates, microbursts can also generate from heavy precipitation.
Microbursts are quick-hitting events and are extremely dangerous to aviation. Microbursts are sub-classified as dry or wet microbursts, depending on how much rain accompanies the microburst when it reaches the ground.
Mooi om hier nog een bekende naam van Weerplaza tegen te komen!
Good seen, Marie.
Would this be an example of a Helm cloud of the type seen in the Lake District and Yorkshire, for example, Ribbleshead railway viaduct?
A soothingly quiet muted vista with the clouds complimenting and setting off the overall majestic scenery.
Most pleasing! Thanks much, Reddi, for this shot. It brought back fond memories of my visits to this wonderful part of the world.
Excellent shot, Mike.
This photo is another of your special hallmark.
Yes thanks Laurence you got it in one. I just love the drama of lightning photography and have taught myself how to reliably do it. My preference is single lightning strike rather than multiple.
