How does a hurricane form?

Answer

A hurricane is actually a low pressure area as we also know it. But then a tropical low pressure area. A hurricane is a tropical storm with high winds (more than 117 km/h).
You can best compare a hurricane to a steam engine. In a steam engine, heat is actually converted into motion (for example, a steam train). The same thing actually happens in a hurricane.

The heat source of the hurricane machine is the warm ocean water in the tropics. The surface temperature must be at least 26.5°C to initiate the hurricane engine. That warm ocean water evaporates and rises. But at more than 10 km altitude in the atmosphere (at the tropopause) the temperature is lower than -65°C. There the evaporated water condenses again. This gives you extra suction, so extra evaporation … and the hurricane machine is in motion.

Hurricanes can only occur where the ocean water is warmer than 26.5°C. So, for example, not in the North Sea, but this also means that once a hurricane “goes ashore”, the engine of the machine stops. After all, warm ocean water no longer evaporates. You also notice that once a hurricane makes landfall, it loses strength very quickly and just becomes a tropical low pressure area.
