  2. Tornado - Wikipedia

    en.wikipedia.org/wiki/Tornado

    Definitions. A tornado is a violently rotating column of air, in contact with the ground, either pendant from a cumuliform cloud or underneath a cumuliform cloud, and often (but not always) visible as a funnel cloud. [ 20 ] For a vortex to be classified as a tornado, it must be in contact with both the ground and the cloud base.

  3. Tornadogenesis - Wikipedia

    en.wikipedia.org/wiki/Tornadogenesis

    Tornadogenesis is the process by which a tornado forms. There are many types of tornadoes, varying in methods of formation. Despite ongoing scientific study and high-profile research projects such as VORTEX, tornadogenesis is a volatile process and the intricacies of many of the mechanisms of tornado formation are still poorly understood. [1][2 ...

  4. Severe weather - Wikipedia

    en.wikipedia.org/wiki/Severe_weather

    Severe weather is any dangerous meteorological phenomenon with the potential to cause damage, serious social disruption, or loss of human life. [1][2][3] These vary depending on the latitude, altitude, topography, and atmospheric conditions. High winds, hail, excessive precipitation, and wildfires are forms and effects, as are thunderstorms ...

  5. Tornado preparedness - Wikipedia

    en.wikipedia.org/wiki/Tornado_preparedness

    The term " tornado preparedness " refers to safety precautions made before the arrival of and during a tornado. Historically, the steps taken have varied greatly, depending on location, or time remaining before a tornado was expected. For example, in rural areas, people might prepare to enter an external storm cellar, in case the main building ...

  6. Atmospheric convection - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_convection

    A tornado is a dangerous rotating column of air in contact with both the surface of the earth and the base of a cumulonimbus cloud (thundercloud), or a cumulus cloud in rare cases. Tornadoes come in many sizes but typically form a visible condensation funnel whose narrowest end reaches the earth and is surrounded by a cloud of debris and dust.

  7. Inversion (meteorology) - Wikipedia

    en.wikipedia.org/wiki/Inversion_(meteorology)

    Steep canyon walls act as a horizontal barrier, concentrating the smoke within the deepest parts of the canyon and increasing the strength of the inversion. [1] In meteorology, an inversion (or temperature inversion) is a phenomenon in which a layer of warmer air overlies cooler air. Normally, air temperature gradually decreases as altitude ...

  8. Tornado climatology - Wikipedia

    en.wikipedia.org/wiki/Tornado_climatology

    Tornado climatology. Areas worldwide with the highest frequency of tornadoes are indicated by orange shading. Tornadoes have been recorded on all continents except Antarctica. They are most common in the middle latitudes where conditions are often favorable for convective storm development. The United States has the most tornadoes of any ...

  9. Tornado intensity - Wikipedia

    en.wikipedia.org/wiki/Tornado_intensity

    Tornado intensity is the measure of wind speeds and potential risk produced by a tornado. Intensity can be measured by in situ or remote sensing measurements, but since these are impractical for wide-scale use, intensity is usually inferred by proxies, such as damage. The Fujita scale, Enhanced Fujita scale, and the International Fujita scale ...
