Tornado Pictures

tornado pictures A tornado is a violently rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. They are often known as tornadoes, hurricanes, [1] although the word cyclone is used in meteorology in a wider sense, to name any closed low pressure circulation. Tornadoes come in many shapes and sizes, but are usually in the form of a visible condensation funnel, whose narrow end touches the earth and is often surrounded by a cloud of debris and dust. Most tornadoes have wind speeds less than 110 mph (177 km / h),tornado pictures are approximately 250 feet (76 m) across, and travel a few miles (several kilometers) before dissipating. The most extreme tornadoes can attain wind speeds of over 300 miles per hour (483 km / h), stretch more than two miles (3.2 km) across, and stay on the ground for tens of miles (over 100 km).

Various types of tornadoes are landspout, multiple vortex tornado, and waterspout. Tornadoes are characterized by an air flow in the spiral-shaped funnel, the connection or to a large cumulus cumulonimbus.tornado pictures Generally considered non supercell tornadoes that develop in water bodies, but there is disagreement as to whether it should be classified as true tornadoes. These spiraling columns of air frequently develop in tropical areas near the equator, and are less common at high latitudes.tornado pictures [5] Other tornado phenomena that exist in nature are gustnado, dust devil,tornado pictures fire the vortices, and the devil steam.

Tornadoes have been observed on every continent except Antarctica. However, the vast majority of tornadoes occur in the Tornado Alley region, the United States, but they can occur almost anywhere in North America.tornado pictures [6] He also occasionally occur in south-central and eastern Asia, northern and east-central South America, Southern Africa, northwestern and southern Europe,tornado pictures the western and southern Australia and New Zealand. [7] Tornadoes can be detected before or produced through the use of pulse Doppler radar by recognizing patterns in velocity and reflection data, such as hook echoes or balls of debris, as well as the efforts of Observers storm.tornado pictures

There are several scales to assess the strength of tornadoes. The Fujita scale tornadoes by damage rate, and has been replaced in some countries by the Enhanced Fujita scale to date. F0 or EF0 tornado, the weakest category, damages trees but not substantial structures. F5 or EF5 tornado, the strongest category, rips buildings off their foundations and can deform large skyscrapers.tornado pictures The scale ranges from a T0 for similar TORRO extremely weak tornadoes to T11 for the most powerful known tornadoes. [8] The Doppler radar data, photogrammetry, and ground swirl patterns (cycloidal marks) may also be analyzed to determine intensity and assign a rating
