Okay kiddo, have you ever seen a big hurricane on the news? Well, a subtropical cyclone is kind of like a mini version of that!
Imagine a big spinning circle of clouds forming over the ocean. This circle is called a cyclone, and it's caused by warm and cold air mixing together. When the cyclone forms in a certain part of the world, like near the Bahamas or Hawaii, it's called a subtropical cyclone.
Now, you might be wondering what makes it "subtropical." That just means it's not quite as strong as a full-blown hurricane, and it forms in areas with different weather patterns. Instead of being fueled by warm water alone, subtropical cyclones get their strength from both warm and cold air, which makes them a little different from hurricanes.
Even though subtropical cyclones aren't as powerful as hurricanes, they can still cause big waves and winds that make the ocean rough for boats and ships. So, whenever there's a subtropical cyclone forming, people need to be careful and stay prepared, just like they would for any other kind of storm.
