Questions and Answers
What is a tropical cyclone?
A warm-cored, non-frontal synoptic-scale low-pressure system over tropical or subtropical waters around the world with a defined center, atmospheric convection, and a closed wind circulation at the surface.
How long have tropical cyclones been occurring around the world?
For thousands of years, with one of the earliest tropical cyclones on record estimated to have occurred in Western Australia in around 4000 BC.
How are tropical cyclones detected in modern times?
Through satellite imagery, and a tropical cyclone is generally deemed to have formed once mean surface winds in excess of 65 km/h are observed.
Study Notes
What is a Tropical Cyclone?
- A tropical cyclone is a rotating system of clouds and thunderstorms that forms over warm ocean waters in the tropics, characterized by strong winds and heavy rainfall.
- It is fueled by the heat and moisture from the ocean, and can bring catastrophic winds, storm surges, and flooding to coastal communities.
History of Tropical Cyclones
- Tropical cyclones have been occurring around the world for thousands of years, with evidence of their impact dating back to ancient civilizations.
Tropical Cyclone Detection
- In modern times, tropical cyclones are detected using a combination of satellite imagery, radar, and reconnaissance aircraft.
- Satellites in orbit around the Earth can detect the formation of tropical cyclones by tracking cloud patterns, temperature, and humidity.
- Radar systems on the ground and onboard aircraft can provide detailed information on the storm's structure and movement.
- Reconnaissance aircraft, such as NOAA's Hurricane Hunters, fly directly into the storm to collect data on wind speed, pressure, and other vital information.
