Tornadoes

Here's what the government does when there is a tornado.

First the National Weather Service (NWS) analyzes weather data such as atmospheric pressure, wind speed a nd direction at different altitudes, humidity, temperatures and other necessary information. From that data they make predictions about likely weather situations including the possibility of a tornado.

When the conditions are right for a possible tornado, state and local governments monitor weather information and put into effect the emergency plan for plotting and observing severe storms. The NWS monitors conditions and radar, giving live updates and disseminating tornado warnings and watches. State and local government then shares these announcements on the Emergency Broadcast System (EBS). Local government activates its Skywarn system of trained weather spotters to view the storms and look for signs of storm rotation, wall clouds and tornadic downspouts. This information given as updates to State and Local emergency management to keep storm information updated through the EBS.

During the storm, State and Local police and emergency agencies prepare for possible rescue and casualties, firefighting and emergency clearing of debris. Their information and action is coordinated through a State or Local Emergecy Operations Center that collects information and directs coordinated response to the tornado.

If a tornado or tornadic severe storm causes more damage than State and Local governments can deal with, the governor of the state must submit a Disaster Declaration request to the President of the United States to initiate Federal assistance to the affected area. The Federal Emergency Management Agency then sends out Damage Assessment Teams to determine the scope of the disaster. That feedback, along with the size of the affected population is documented and determines whether FEMA is activated.

Upon activation, FEMA, which coordinates the response of 28 Federal agencies from the Corps of Engineers to the Environmental Protection Agency to the Small Business Administration and more coordinates with and at the direction of the affected State and provides assistance to meet the needs of communities. FEMA assists in the form of funds, manpower, equipment, food, water, health care, expertise and other needed assistance.

FEMA is either pre staged or immediately boots on the ground as soon as the Disaster Declaration is made.

In the past, FEMA coordinates with the State by providing a 75/25 match, which means that FEMA pays for 75 percent of disaster expenses and the State provides 25 percent assistance. In catastrophic disasters, this formula may change.

On the ground FEMA sets up a Joint Field Office (JOF) and Disaster Assistance Centers in specific areas for disaster survivors to apply for help from the government. These centers often include representatives from other federal and state agencies, community agencies (DMV, Protective Services and County Clerk) Non Governmental Organizations (NGOs) (like American Red Cross and Mennonite Disaster Services), Mental Health counselling and any other helpful organization which chooses to be represented.

FEMA continues to work on Recovery and Mitigation, that is taking actions that would lesson the effects of a similar event in the future, for anywhere from three to ten years. They continue to work with the State on funding repairs of roads, bridges, public buildings and utilites damaged by disaster. Until recently, FEMA's goal for assisting disaster survivors was to get the first personal assistance checks out within 10 days of the declaration.

And that is pretty much how all of government deals with a tornado or any other disaster.

For hurricanes the Saffir Simpson scale is a measure of the storm's windspeeds and the damage they cause. So a category one is 74 to 90 miles per hour. Category 5 is over 157 miles per hour. The scale includes damage designations for each category: 1 some damage, 2. extensive damage, 3. devastating and 4 and 5 catastrophic. Hurricane Katrina came ashore as a category 3. Hurricane Andrew was a category 5.

For Tornados the enhanced Fugita (EF) scale involves wind speed plus damage. So an EF 1 has wind speeds of about 65 to 85 miles per hour and causes some damage to small buildings where an EF 5 indicates winds over 200 miles per hour and catastrophic damage to large buildings, vehicles and trees. The Joplin tornado was an EF 5.

Earthquakes also have ratings based on the type and amount of movement and depth of the epicenter. They are defined by the Richter scale. Low magnitude earthquakes can be rated from about 1.0 to 3.9, are often not even noticed and cause minimal damage. Medium to Moderate earthquakes fall into the 4.0 to 5.9 range causing noticeable shaking and damages. Earthquakes in the 7.0 to 7.9 range are considered major, 8. to 8.9 great and 9.0 to 10 extreme. The earthquake that caused the nuclear accident in Fukishima, Japan in 2011 was described as a 9.0. The 1960 earthquake in Chile was the largest recorded and and was a 9.5.

Tornadoes don't form at an exact temperature, as they depend upon a wide variety of complex factors of which temperature is just one. It is highly unusual to see them in temperatures below 50 degrees Fahrenheit, though not unheard of, particularly at high elevations.

Tornadoes form best when very warm, moist air is available. The most severe events have been preceded be temperatures in the mid 80s to the 90s.

The greatest portion of tornado deaths results from flying debris. Everyday objects and building materials can be turned into deadly projectiles by a strong tornado. Others may die as buildings collapse on them.

In weak tornadoes, which are not often deadly, may cause deaths through toppling trees and other heavy objects or overturning trailers.

In some cases people may be picked up and thrown by the winds of a tornado.

Occasionally there are unusual cases, as tornadoes have been known to do strange things. One man was found impaled on the lid of a washing machine after a tornado destroyed his home.

The messenger brings a warning about impending danger or disaster, urging the recipient to take immediate action to avoid catastrophe. However, she does not heed the warning, either due to disbelief, arrogance, or a sense of inevitability. This refusal to listen ultimately leads to dire consequences, highlighting the importance of heeding warnings and being aware of potential threats. The situation serves as a cautionary tale about the repercussions of ignoring critical advice.

There is no specific word for a scientist who studies tornadoes. Such scientists would fall under the general label of meteorologists; weather scientists.

A summated rating scale, often referred to as a Likert scale, is a type of survey tool used to measure attitudes or opinions by asking respondents to indicate their level of agreement or disagreement with a series of statements. Each statement is assigned a numerical value, and respondents provide ratings on a predefined scale, typically ranging from "strongly disagree" to "strongly agree." The scores for individual items are then summed to produce an overall score that reflects the respondent's attitude or level of agreement on the topic being measured. This approach allows for more nuanced data collection compared to simple yes/no questions.

A rotating updraft in a thunderstorm, often referred to as a mesocyclone, is a column of rising air that rotates around a vertical axis. This phenomenon is crucial for the development of severe thunderstorms, including supercell storms, as it helps to organize the storm's structure and can lead to the formation of tornadoes. The rotating updraft separates the storm's inflow of warm, moist air from the outflow of cooler air, enhancing the storm's intensity and longevity.

As of October 2023, there have been approximately 1,000 tornadoes reported in the United States over the past 12 months. The number can vary significantly year to year based on weather patterns and conditions. For the most accurate and up-to-date statistics, it's best to consult the National Weather Service or the Storm Prediction Center.

Tornadoes can form when there are significant temperature differences in the atmosphere, typically when warm, moist air at the surface rises and meets cooler, drier air aloft. This instability is often found in conditions where surface temperatures are around 70°F to 90°F (21°C to 32°C), combined with strong wind shear. However, tornadoes can develop in various temperature settings, as the key factors are the interaction of different air masses and atmospheric conditions rather than a specific temperature threshold.

Most houses are typically covered with roofing materials such as asphalt shingles, metal, tiles, or slate. Asphalt shingles are the most common due to their affordability and ease of installation. Other materials like metal and tiles offer durability and aesthetic appeal, while slate provides a long-lasting and elegant option. The choice of roofing material often depends on factors like climate, budget, and architectural style.

Spring is often the windiest time of the year due to the significant temperature differences between warm and cold air masses. As the sun's intensity increases, warm air rises, creating low-pressure areas, while cooler air moves in to fill those gaps, resulting in increased wind activity. Additionally, the transition from winter to summer can lead to turbulent weather patterns, further contributing to windy conditions. These dynamics are especially pronounced in spring, making it a season characterized by blustery weather.

Getting under a bed during a tornado is not recommended as a safe option. Instead, it's better to seek shelter in a small, windowless interior room on the lowest floor of your home, such as a basement or storm cellar. If these options are unavailable, cover yourself with a heavy blanket or mattress to protect against debris. Prioritizing a sturdy structure is crucial for safety during a tornado.

The Great Plains are susceptible to several natural hazards, including tornadoes, which are common due to the region's unique weather patterns. Severe thunderstorms can lead to hail and flash flooding. Additionally, droughts are a frequent concern, impacting agriculture and water supply. Winter storms and blizzards can also pose significant challenges during colder months.

If a tornado approaches while you're in a vehicle, the safest option is to find a sturdy building and seek shelter inside. If no shelter is available, park your vehicle in a low-lying area, such as a ditch, and cover your head with your arms to protect yourself from debris. Avoid staying in your vehicle, as it can be lifted or tossed by the tornado. Always stay alert to the storm's path and conditions.

The Daultipur and Salturia tornadoes occurred in Bangladesh on April 26, 1989. The tornadoes lasted for approximately 30 minutes, causing extensive damage and numerous casualties in the affected areas. They are remembered as some of the deadliest tornadoes in the region's history.

Tornadoes form in "Tornado Alley" due to the unique atmospheric conditions present in this region, which typically includes warm, moist air from the Gulf of Mexico colliding with cold, dry air from Canada. This clash creates strong thunderstorms, particularly supercells, which can produce rotating updrafts known as mesocyclones. The flat terrain of the Great Plains also allows for these storms to develop without obstruction, increasing the likelihood of tornado formation. Additionally, the high frequency of severe weather events in this area contributes to the prevalence of tornadoes.

Tornadoes play a crucial role in the Earth's atmospheric dynamics by contributing to the redistribution of energy and moisture within the atmosphere. They can help to maintain the balance of weather systems by influencing local climatic conditions. Additionally, studying tornadoes enhances our understanding of severe weather patterns, which is vital for improving forecasting and safety measures, ultimately protecting lives and property. While they can be destructive, their study helps mitigate their impact on communities.

Wind shear can result in the formation of various weather phenomena, most notably severe thunderstorms, tornadoes, and microbursts. It refers to the change in wind speed and direction with altitude, which can create instability in the atmosphere. This instability can enhance the development of rotating updrafts in thunderstorms, leading to the potential for severe weather events. Additionally, wind shear can impact aviation safety by causing sudden changes in airflow, affecting takeoffs and landings.

Chipmunks can cause damage by digging burrows in gardens and landscapes, which can undermine plant roots and lead to soil erosion. They may also consume and damage fruits, vegetables, and flowers. Additionally, their burrowing can disturb the foundations of structures and create issues with landscaping. In some cases, they can invade attics or garages, leading to potential property damage and sanitation concerns.

To stay safe from a tornado in a hotel, first locate the emergency plan provided by the hotel, which typically includes designated safe areas such as interior rooms or basements. Avoid windows and doors, and take cover under sturdy furniture if possible. Use heavy blankets or pillows to protect yourself from debris. Additionally, stay informed by listening to weather alerts on your phone or a weather radio.

When using electronic devices or communicating in public spaces, be aware that eavesdroppers may be listening in on your conversations. Avoid discussing sensitive information in places where others can easily overhear, such as cafes or public transportation. Additionally, ensure your devices have updated security measures to prevent unauthorized access. Being cautious about your surroundings and the content of your conversations can help protect your privacy.

The most important medium for Tin Pan Alley songs at the turn of the century was sheet music. This format allowed composers and songwriters to publish and distribute their works widely, enabling amateur musicians to perform popular songs in homes and social settings. The rise of the phonograph later expanded the reach of these songs, but sheet music remained the primary vehicle for showcasing and promoting new music during this era.

People do not directly make tornadoes; however, human activities can influence the conditions that lead to tornado formation. For example, urbanization and land use changes can affect local weather patterns and increase surface temperatures, potentially altering storm systems. Additionally, climate change driven by human activities may increase the frequency and intensity of severe weather events, including tornadoes. Nevertheless, tornadoes themselves are natural phenomena resulting from specific atmospheric conditions.
