The tornado reached EF5 intensity, with winds exceeding 200 mph.
The weather in 2012 varied greatly around the world, influenced by a mix of natural climate patterns, such as El Niño and La Niña, and human-induced factors. Here are some highlights of significant weather events and trends from that year: 1. **United States**: - The summer of 2012 was marked by one of the most severe droughts in the Midwest and Great Plains, impacting agriculture significantly.
The weather of 2011 was notable for a variety of extreme weather events across the globe. Some significant highlights include: 1. **Tornadoes in the United States**: One of the most devastating tornado seasons occurred in 2011, with an outbreak in April that included the Joplin tornado, which killed over 150 people and caused extensive damage.
The weather in 2010 was marked by several notable events globally, including extreme temperatures, significant storms, and unusual weather patterns. Some key highlights include: 1. **Cold Weather in Europe**: A harsh winter hit much of Europe in late 2009 into early 2010, with heavy snowfall and freezing temperatures causing widespread disruption. 2. **Heat Waves**: Various parts of the world experienced heat waves.
The weather in 2009 varied greatly around the world, with significant climate events influencing various regions. Here are some notable weather-related events and trends from that year: 1. **Global Temperature**: 2009 was one of the cooler years of the decade, with global average temperatures slightly below the long-term trend. 2. **El Niño**: Early in the year, the tail end of the El Niño phenomenon influenced weather patterns, leading to unusual conditions in several regions.
The weather of 2008 varied widely around the globe, as it does in any given year. Significant weather events included: 1. **Severe Storms**: Many regions experienced severe storms, including tornadoes in the United States, particularly in the Midwest and South. Notably, a series of tornado outbreaks occurred in April 2008. 2. **Hurricanes**: In the Atlantic, the hurricane season was above average.
The weather of 2007 varied significantly across different regions of the world. Here are some notable highlights from that year: 1. **Global Temperatures**: 2007 was characterized by above-average global temperatures, continuing the trend of increasingly warm years attributed to climate change. 2. **Severe Weather Events**: - **United States**: Several states experienced extreme weather, including tornadoes, severe thunderstorms, and flooding.
The weather in 2006 varied widely around the globe, as it typically does in any given year, influenced by seasonal changes, climate patterns, and regional effects. Here are some key weather-related highlights from 2006: 1. **Hurricanes**: The Atlantic hurricane season produced several notable storms, including Hurricane Ernesto and Hurricane Gordon. While the overall season was less active than previous years, it still caused significant damage in some areas.
The weather of 1946 varied significantly across different regions of the world, as it does every year. If you are looking for specific weather events or climatic conditions related to that year, the following points are noteworthy: 1. **Post-War Climate**: 1946 was a period following World War II, and the impacts of the war on human activity and industrial output may have had localized effects on the environment and weather patterns.
Weather-related pains, often referred to as "weather pains," are discomforts or aches that some individuals experience in relation to changes in the weather or climate. While not an officially recognized medical condition, many people report an increase in joint pain, headaches, or other types of discomfort when certain weather conditions occur. Common factors that may contribute to weather-related pains include: 1. **Barometric Pressure Changes**: Some people are sensitive to changes in barometric pressure.
Thunderstorm asthma is a phenomenon where a sudden increase in asthma attacks occurs during or after a thunderstorm. This happens when specific weather conditions lead to the release of pollen grains or mold spores into the air, which can then be inhaled. The combination of humidity, wind, and changes in atmospheric pressure can cause the pollen grains to rupture, releasing smaller particles that can penetrate deep into the lungs, triggering asthma symptoms in susceptible individuals.
Springtime lethargy, often referred to in a more general context as "spring fatigue" or "spring lethargy," is a phenomenon where individuals experience feelings of tiredness, low energy, or lethargy as the seasons change from winter to spring. This may be attributed to several factors: 1. **Changing Light Exposure**: With longer daylight hours, the body adjusts to increased light exposure, which can disrupt sleep patterns and circadian rhythms, leading to fatigue.
Seasonal effects on suicide rates refer to the patterns and fluctuations in suicide incidence that correspond to different times of the year. Research has shown that there are indeed seasonal trends in suicide rates, although these can vary by geographic location, cultural factors, and individual circumstances. Here are some key points related to seasonal effects on suicide rates: 1. **Seasonality**: Certain studies have found that suicide rates tend to increase during specific seasons.
Seasonal Affective Disorder (SAD) is a type of depression that occurs at a specific time of year, most commonly during the fall and winter months when there is less natural sunlight.
Lightning injury refers to damage caused by lightning strikes, which can result in a range of injuries, both physical and psychological. These injuries can vary in severity and can affect individuals who are struck directly by lightning, as well as those who are nearby when a strike occurs. ### Types of Lightning Injuries: 1. **Direct Strike**: A person struck directly by lightning can experience severe injuries, including burns, cardiac arrest, and neurological damage. The high voltage can cause immediate physiological disruptions.
Frostbite is a medical condition that occurs when skin and other tissues freeze due to exposure to extremely cold temperatures. It typically affects fingers, toes, ears, and the nose, which are extremities that are often exposed to cold air. The risk of frostbite increases with wind chill, wet conditions, and prolonged exposure to low temperatures.
Foehn wind, also spelled "Föhn wind," is a warm, dry wind that descends the leeward side of a mountain range. It is associated with orographic lift, where moist air is forced to rise as it encounters the mountains. As the air rises, it cools and can lead to precipitation on the windward side, but when the air descends on the leeward side, it warms and dries out.
Fermi's interaction refers to the fundamental weak nuclear force that governs the interactions of elementary particles, particularly those involving leptons (like electrons and neutrinos) and quarks. This interaction is largely described within the framework of the electroweak theory, which unifies the electromagnetic force and the weak nuclear force. The term "Fermi interaction" is often associated with Enrico Fermi, who made significant contributions to the understanding of weak interactions in the early 20th century.
"Wax fire" often refers to a specific type of fire that can occur in environments where flammable wax is present, such as candle-making or candle-burning scenarios. It can also sometimes refer to incidents involving wax or waxy substances catching fire, primarily due to heat sources or improper handling. In a more general sense, wax is a combustible material, and if it reaches its flash point, it can ignite.
Wax carving is a sculpting technique that involves creating three-dimensional designs from wax. This method is commonly used in various applications, including jewelry making, model making, and in the preparation of objects for metal casting. In jewelry making, artisans use wax to create detailed patterns and shapes that are later cast in metal using the lost-wax casting process.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
