Okay kiddo, a tropical cyclone is a big, strong storm that forms over warm ocean waters. Scientists called meteorologists use many tools to observe these storms.
One of the tools they use are satellites, which are like cameras that take pictures of the storm from space. Scientists look at these pictures to see how big the storm is and how fast it's moving.
Another tool they use is called radar, which is like a big machine that can see through clouds and rain. It lets the scientists know how intense the storm is, and where the strongest winds are.
Meteorologists also use special planes called hurricane hunters. These planes fly into the storm and drop devices called dropsondes. These dropsondes measure things like air pressure, temperature, wind speed, and humidity. This information helps the scientists predict where the storm will go and how strong it will be.
In addition to these tools, scientists also rely on data from buoys, which are floating devices in the ocean that measure things like wind speed, air pressure, and water temperature.
All of this information is collected and analyzed by the scientists to help them better understand these big, dangerous storms and to help keep people safe by predicting where they will go and how strong they will be.
