We often hear about terms like Typhoon, Hurricane, Cyclone, Tropical Depression and Tropical Storm. So what do they all mean? And what are the processes to actually create a hurricane?
With the media-grabbing Atlantic Hurricane season upon us we thought we’d take a closer look.
Firstly whether you call it a Typhoon a Hurricane or a Cyclone they are all the same thing – they just form in different parts of the world.
Three Names for the Same Thing
Another thing all these tropical storms have in common is how they are made…
How a storm is made

I didn’t know about Step 2…that’s my knowledge increase for the day 🙂
So, what is the highest category we’ve experienced in NZ? I’m doubting we’ve ever had a Category 5!

Our record books aren’t very good in this area mainly because we so rarely get a tropical storm and they technically aren’t tropical cyclones when they reach us (we’re too far south).
The wind speeds recorded during the Wahine Disaster were certainly around Category 5 but I would imagine they were gusts not sustained winds…and they were also localised to Wellington indicating it was the geography that lead to those huge winds (from memory they were recorded gusting to 280km/h) and not that low itself.
At a guess I’d say Cat 3-type winds is something NZ would get every few decades – most likely coming from the Southern Ocean though so definitely not classed as a cyclone and probably only affecting remote regions.
