Types of Tornadoes in Oklahoma
Oklahoma is prone to a variety of tornado types, each with distinct characteristics and behaviors. Understanding these differences is crucial for assessing tornado risks and developing effective preparedness plans.
Supercell Tornadoes
Supercell tornadoes are the most powerful and destructive type, characterized by their long-lived and rotating updrafts. They can produce large, violent tornadoes that travel for extended distances, often causing catastrophic damage. The El Reno tornado of 2013, with wind speeds estimated at 302 mph, is an infamous example of a supercell tornado.
Landspout Tornadoes
Landspout tornadoes form from weak updrafts and are typically weaker than supercell tornadoes. They are often short-lived and narrow, with a lifespan of only a few minutes. Landspout tornadoes commonly occur in open areas and pose less of a threat to structures compared to supercell tornadoes.
Gustnadoes
Gustnadoes are small, weak tornadoes that form from gust fronts, the leading edge of a thunderstorm’s outflow. They are typically short-lived and do not cause significant damage. Gustnadoes are often observed in Oklahoma during the spring and summer months.
Tornado Safety and Preparedness
Oklahoma experiences a significant number of tornadoes each year, making it crucial for residents to prioritize tornado safety and preparedness. Understanding the warning systems in place and developing a comprehensive tornado safety plan can significantly increase the chances of survival during a tornado event.
The National Weather Service (NWS) issues tornado warnings when a tornado is imminent or already occurring. These warnings are disseminated through various channels, including television, radio, NOAA weather radios, and mobile phone alerts. Upon receiving a tornado warning, individuals should seek immediate shelter in a designated safe location.
Creating a Tornado Safety Plan
A well-defined tornado safety plan Artikels the actions to be taken before, during, and after a tornado event. The plan should include designated safe shelters, evacuation routes, and communication procedures for family members.
Identifying a sturdy shelter is paramount. Interior rooms on the lowest level of a building, such as a basement or storm cellar, provide the best protection. If an underground shelter is not available, an interior room without windows, such as a bathroom or closet, can serve as an alternative.
Building a Storm Shelter
Building a storm shelter is an effective way to enhance tornado safety. Storm shelters can be constructed underground or above ground and should meet specific building codes and standards. Underground storm shelters offer the highest level of protection, while above-ground shelters provide a reasonable alternative.
When constructing a storm shelter, it is essential to consider factors such as location, materials, and ventilation. The shelter should be situated in a well-drained area away from trees and power lines. Concrete or steel are recommended materials for storm shelter construction, and adequate ventilation is crucial to prevent carbon dioxide buildup.

Tornado Research and Forecasting
Research efforts are continuously improving tornado forecasting and detection. Advances in technology have played a crucial role in predicting and tracking tornadoes, leading to timely warnings and saving lives.
Observational Networks, Oklahoma tornado
Researchers are expanding observational networks, including Doppler radars, weather balloons, and storm spotters. These networks provide real-time data on atmospheric conditions, allowing meteorologists to monitor tornado development and movement.
Numerical Weather Prediction Models
Computer models that simulate atmospheric conditions are used to forecast tornadoes. These models incorporate data from observational networks and advanced algorithms to predict the likelihood and severity of tornadoes.
Supercomputing and Artificial Intelligence
Supercomputers and artificial intelligence (AI) are enhancing the capabilities of numerical weather prediction models. AI algorithms can analyze vast amounts of data, identify patterns, and improve forecast accuracy.
Success Stories
Successful tornado forecasts have saved countless lives. For example, in 2013, the National Weather Service issued timely warnings for the Moore, Oklahoma tornado, allowing residents to seek shelter and minimize casualties.
