If you have a very dry environment near the ground you can have storms where the water evaporates before reaching it. We call this virga (pictured) when we’re able to see it.Â
Now with thunderstorms, so long as we have enough motion within the storm to build up static, we’ll produce lightning. You can have that process happen then have no rain reach the ground before it all evaporates. We call this a dry thunderstorm and it can be rather problematic in starting wildfires.
After >20 long days of little to no rain, Ireland has welcomed back its familiar friend and with it, the amazing ‘it’s finally raining’ smell.
This smell, which is typically associated with rainfall after a dry period, is termed Petrichor; from the Greek words ‘petra’ meaning stone and ‘ichor’ which refers to the golden fluid that was said to flow through the veins of the gods and the immortals in Greek Mythology.
Microbursts are very seldom talked about, despite the fact that they pack all the punch of a tornado and have been known to push passenger jets right out of the sky, causing several fatal crashes over the years. A microburst is a sudden and very powerful downdraft of wind, and they are highly localised. They are commonly found in thunderstorms and involve a powerful downdraft of wind being pushed against the ground and then bursting out in all directions, creating sudden and powerful gales that can reach speeds of 150mph.
As seen in the video, the storm goes from what looks like an average storm to what could easily be mistaken for a large tornado, all in a matter of seconds. Perhaps the most unnerving part is at 0:28, where the microburst can clearly be seen advancing towards the cameraman, before easily ripping a large tree in half.
