Dear Brother,
It’s been 3 months but please don’t panic, I’m fine. I’ve wanted to write this letter to you ages ago but I haven’t had the time. I must have the worst luck to move to Darwin a few weeks before Cyclone Tracy hit. And it hit during Christmas Eve too! Horrible isn’t it? But don’t worry, I made it out in one piece. Knowing you, you probably want the details of this experience so I’ve decided to tell you everything that happened to me within this letter starting from now. As you know, Cyclone Tracy hit Darwin in 1974 and nearly destroyed everything! I think there were around 70 deaths from it and I’m glad I wasn’t one of them. I took some photos of this whole disaster which you can find at the end of this letter too. Now that I have the basics out of the way, I can get started with my experience of this terrible natural disaster!
Well a good way to start this is how I believe Cyclone Tracy was formed in the first place. I did some research out of curiosity and got this. A tropical cyclone like Cyclone Tracy is created by a group of thunderstorms over warm tropical waters. The small winds of those thunderstorms evaporate water from the ocean surface and thus transferring energy from the ocean into the atmosphere. While the winds flow into that disturbance, they form clouds and precipitation. This makes the air warm and buoyant like a hot air balloon and that also encourages for more warm air to flow in from the outside. As all this warm air is flowing in, it is making a spiral shape because of the rotation of the Earth and as a result, making the wind and incoming energy speed up. Once the winds reach a certain speed, a tropical cyclone is born, or in this case, Cyclone Tracy is created. Cyclone Tracy actually began as a humid, low cyclone a few days before hitting Darwin so it came a quite a shock, when the speed rose to 217km/hr and formed 700km north-northeast of Darwin.
