Understanding Tornado Basics
Tornadoes are violent rotating columns of air that extend from a thunderstorm to the ground. They are one of nature's most destructive forces, capable of causing significant damage to property and loss of life. In Illinois, tornadoes can occur at any time of the year, but they are most common during the spring and early summer months.
What Causes Tornadoes?
Tornadoes form when warm, moist air from the Gulf of Mexico collides with cool, dry air from Canada. This clash creates instability in the atmosphere, leading to the formation of thunderstorms. If conditions are right, these thunderstorms can develop into supercells, which are the most likely to produce tornadoes.
Types of Tornadoes
- Supercell Tornadoes: The most common and often the most destructive type of tornado. They are associated with supercell thunderstorms.
- Non-Supercell Tornadoes: These include waterspouts and landspouts, which are generally weaker and less destructive.
Tornado Warning Systems in Illinois
Tornado warnings in Illinois are issued by the National Weather Service (NWS) when a tornado has been sighted or indicated by radar. These warnings are broadcast through various channels, including television, radio, and mobile apps, to ensure that residents are informed and can take appropriate action.
How Tornado Warnings Are Issued
The NWS uses advanced radar technology to detect tornadoes and issue warnings. Doppler radar is particularly effective in identifying the rotation within thunderstorms that can lead to tornado formation. Once a tornado is detected, the NWS issues a warning, which is then disseminated to the public through emergency alert systems.
History of Tornadoes in Illinois
