Tornadoes Of 2017
This page documents notable tornadoes and tornado outbreaks worldwide in 2017. Strong and destructive tornadoes form most frequently in the United States, Brazil, Bangladesh, and East India, Eastern India, but they can occur almost anywhere under the right conditions. Tornadoes also develop occasionally in southern Canada during the Northern Hemisphere's summer and somewhat regularly at other times of the year across Europe, Asia, Argentina and Australia. Tornadic events are often accompanied with other forms of severe weather, including strong thunderstorms, strong winds, and hail. There were 1,522 reports of tornadoes in the United States in 2017, of which 1,418 were confirmed. Worldwide, 43 fatalities were confirmed in 2017: 35 in the United States, five in China, two in Paraguay, and one in Brazil. The tornado season in 2017 started exceptionally early, having the second most active January since records began in 1950, and one of the most active first quarters in recorded hist ...

Tornado Outbreak Of February 28 – March 1, 2017
The tornado outbreak of February 28 – March 1, 2017 was a widespread and significant outbreak of tornadoes and severe weather that affected the Midwestern United States at the end of February 2017 and beginning of March. Fueled by the combination of ample instability, strong wind shear, and rich low-level moisture, the event led to 71 confirmed tornadoes and thousands of other non-tornadic severe weather reports. The most notable aspect of the outbreak was a long-tracked EF4 tornado—the first violent tornado of 2017 and the first violent tornado during the month of February since the 2013 Hattiesburg, Mississippi tornado—that tracked from Perryville, Missouri to near Christopher, Illinois, killing one person. Three EF3 tornadoes were recorded during the event, including one that caused two fatalities in Ottawa, Illinois, one that caused a fatality near Crossville, Illinois, Crossville, and one that heavily damaged or destroyed homes in and around Washburn, Illinois, Washburn.

Bunkie, Louisiana
Bunkie is a city in Avoyelles Parish, Louisiana, United States. The population was 4,171 at the 2010 census. History Bunkie was founded as a station terminus on the Texas and Pacific Railroad line. It was named for the daughter (whose nickname was "Bunkie") of the original landowner. The federal post office in town contains a mural, ''Cotton Pickers'', painted in 1939 during the Great Depression by Caroline Speare Rohland. Federally commissioned murals were produced from 1934 to 1943 in the United States through the Section of Painting and Sculpture, later called the Section of Fine Arts, of the Treasury Department. This work was part of the effort by the federal government to employ artists during the difficult Depression years. The area around Bunkie is devoted to agriculture; since the late 20th century, corn has been an important commodity crop. Since 1987, Bunkie has hosted the annual Louisiana Corn Festival during the second full weekend of June. Geography According to t ...

Atmospheric Convection
Atmospheric convection is the result of a parcel-environment instability, or temperature difference layer in the atmosphere. Different lapse rates within dry and moist air masses lead to instability. Mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. Special threats from thunderstorms include hail, downbursts, and tornadoes. Overview There are a few general archetypes of atmospheric instability that are used to explain convection (or lack thereof). A necessary (but not sufficient) condition for convection is that the environmental lapse rate (the rate of decrease of temperature with height) is steeper than the lapse rate experienced by a rising parcel of air. When this condition is met, upward-displaced air parcels can become buoyant and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmospheric Instability
Atmospheric instability is a condition where the Earth's atmosphere is generally considered to be unstable and as a result the weather is subjected to a high degree of variability through distance and time. Atmospheric stability is a measure of the atmosphere's tendency to discourage or deter vertical motion, and vertical motion is directly correlated to different types of weather systems and their severity. In unstable conditions, a lifted thing, such as a parcel of air will be warmer than the surrounding air at altitude. Because it is warmer, it is less dense and is prone to further ascent. In meteorology, instability can be described by various indices such as the Bulk Richardson Number, lifted index, K-index, convective available potential energy (CAPE), the Showalter, and the Vertical totals. These indices, as well as atmospheric instability itself, involve temperature changes through the troposphere with height, or lapse rate. Effects of atmospheric instability in mois ...

Trough (meteorology)
A trough is an elongated region of relatively low atmospheric pressure without a closed isobaric contour that would define it as a low pressure area. Since low pressure implies a low height on a pressure surface, troughs and ridges refer to features in an identical sense as those on a topographic map. Troughs may be at the surface, or aloft. Near-surface troughs sometimes mark a weather front associated with clouds, showers, and a wind direction shift. Upper-level troughs in the jet stream (as shown in diagram) reflect cyclonic filaments of vorticity. Their motion induces upper-level wind divergence, lifting and cooling the air ahead (downstream) of the trough and helping to produce cloudy and rain conditions there. Unlike fronts, there is not a universal symbol for a trough on a surface weather analysis chart. The weather charts in some countries or regions mark troughs by a line. In the United States, a trough may be marked as a dashed line or bold line. In the UK, Hong Kong ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesoscale Convective System
A mesoscale convective system (MCS) is a complex of thunderstorms that becomes organized on a scale larger than the individual thunderstorms but smaller than extratropical cyclones, and normally persists for several hours or more. A mesoscale convective system's overall cloud and precipitation pattern may be round or linear in shape, and include weather systems such as tropical cyclones, squall lines, lake-effect snow events, polar lows, and mesoscale convective complexes (MCCs), and generally forms near weather fronts. The type that forms during the warm season over land has been noted across North and South America, Europe, and Asia, with a maximum in activity noted during the late afternoon and evening hours. Forms of MCS that develop within the tropics use either the Intertropical Convergence Zone (ITCZ) or monsoon troughs as a focus for their development, generally within the warm season between spring and fall. One exception is that of lake-effect snow bands, which form d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tornado
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. It is often referred to as a twister, whirlwind or cyclone, although the word cyclone is used in meteorology to name a weather system with a low-pressure area in the center around which, from an observer looking down toward the surface of the Earth, winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern. Tornadoes come in many shapes and sizes, and they are often visible in the form of a condensation funnel originating from the base of a cumulonimbus cloud, with a cloud of rotating debris and dust beneath it. Most tornadoes have wind speeds less than , are about across, and travel several kilometers (a few miles) before dissipating. The most extreme tornadoes can attain wind speeds of more than , are more than in diameter, and stay on the ground for more than 100 k ...
