Can someone identify these phenomena?

In summary, these videos were recorded at Angicos, a small town of Brazil. They are records of the same phenomenon: can someone identify it? A tornado? A gustnado? A dust evil?

Looks like a tornado to me.

these are not cetripetal vortexs.
I only glanced at the first one.

Dust devils then.

The first one is a gustnado often seen along the gust front of an approaching storm
its not in the right place in the stormcell for it to be a tornado.

The second one is very indistinct... I will go with gustnado for similar reasons to the first videoclip.

the third one hmmmmm... unfortunately the cloudbase directly above the rotation was never shown and without that info I cannot tell you if its a gustnado or a tornado

That one really got its act together after coming off the water, didnt it ! cool

I get to see all sorts of wonderful things like that during my stormchasing trips around the USA and Australia

All 3 are clearly related to the storm activity which makes them gustnadoes / tornadoes
its their positional relationship to the stormcell which determines which of those 2 they are.
They are all typical vortex's ... there is no question of that! :)

Evo's video clearly shows a very nice dust devil ( willi willi in Australia, Aboriginal name for them) Often seen on sunny summer days when heat rising from the hot dry ground can start rotating. Travelling through the outback of Australia, my wife and I have seen many dust devils, sometimes 2 - 3 visible at the same time spread across the landscape

cheers
Dave

Ooh, thanks Dave, that's why I couldn't tell why it looked like a mix between a tornado and a dust devil, it's a gustnado. Never heard of it, and I live in the midwest.

1. What are some common characteristics used to identify a phenomenon?

Some common characteristics used to identify a phenomenon include its observable properties, patterns, and behaviors. Scientists may also use specific measurements or data to identify a phenomenon.

2. How do scientists determine the cause of a phenomenon?

Scientists use the scientific method to determine the cause of a phenomenon. This involves making observations, forming hypotheses, conducting experiments, and analyzing data to support or reject the hypotheses.

3. Can multiple phenomena occur simultaneously?

Yes, multiple phenomena can occur simultaneously. It is not uncommon for multiple phenomena to interact and influence each other.

4. Are all phenomena predictable?

No, not all phenomena are predictable. Some phenomena, particularly those in complex systems, may exhibit chaotic behavior and cannot be accurately predicted.

5. How do scientists ensure their identification of a phenomenon is accurate?

Scientists use rigorous methods and multiple lines of evidence to ensure the accuracy of their identification of a phenomenon. This includes peer review, replication of experiments, and careful analysis of data.
