December 2021 Midwest Derecho And Tornado Outbreak
On December 15, a rapidly-deepening low-pressure area contributed to a historic expanse of inclement weather across the Great Plains and Midwestern United States, resulting in an unprecedented December derecho and tornado outbreak across portions of the Northern United States, a region normally affected by snow and cold weather during this time of year. Non-thunderstorm winds spurred the formation of rapidly-moving fires across Colorado and western Kansas, with attendant dust and debris spreading eastward. From central Kansas northeastward into eastern Wisconsin, the powerful derecho led to hundreds of damaging wind reports. At least 57 hurricane-force wind reports were received by the National Weather Service, signaling the most prolific wind event in the United States dating back to at least 2004. Numerous embedded circulations within this rapidly-progressing derecho produced dozens of tornadoes, including 33 that were rated EF2. The culmination of non-thunderstorm, th ...

Russell, Kansas
Russell is the most populous city in and the county seat of Russell County, Kansas, United States. As of the 2020 census, the population of the city was 4,401. History In 1865, the Butterfield Overland Despatch established a short-lived station named Fossil Creek Station along its route from Atchison, Kansas to Denver near the site of modern Russell. In 1867, the Kansas Pacific Railway reached the area and built its own station, also named Fossil Creek, later just Fossil, north of the Butterfield station. That same year, the Kansas Legislature established the surrounding area as Russell County. In 1871, colonists from Ripon, Wisconsin established a permanent settlement at Fossil Station, renaming it Russell after the county. Russell was incorporated and named the provisional county seat in 1872, and, after a two-year dispute with neighboring Bunker Hill, it became the permanent county seat in 1874. In 1876, Volga Germans, mostly from the area around Saratov and Samara in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low-pressure Area
In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), while high-pressure areas are associated with lighter winds and clear skies. Winds circle anti-clockwise around lows in the northern hemisphere, and clockwise in the southern hemisphere, due to opposing Coriolis force, Coriolis forces. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the Atmosphere of Earth, atmosphere (aloft). The formation process of a low-pressure area is known as cyclogenesis. In Meteorology#Dynamic meteorology, meteorology, atmospheric divergence aloft occurs in two kinds of places: * The first is in the area on the east side of upper Trough (meteorology), troughs, which form half of a Rossby wave within the Westerlies (a trough (meteorology), trough with la ...

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] |
Central United States
The Central United States is sometimes conceived as between the Eastern and Western as part of a three-region model, roughly coincident with the U.S. Census' definition of the Midwestern United States plus the western and central portions of the U.S. Census' definition of the Southern United States. The Central States are typically considered to consist of North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, Texas, Minnesota, Iowa, Missouri, Arkansas, Louisiana, Wisconsin, Illinois, Michigan, Indiana, Ohio, Kentucky, Tennessee, West Virginia, Mississippi and Alabama. Chicago is the area's largest city and metropolitan area; other large cities with large metropolitan areas would be Houston, Dallas, Fort Worth, San Antonio, Austin, Oklahoma City, Tulsa, Kansas City, Kansas and Kansas City, Missouri, Topeka, Wichita, Omaha, Nebraska and Lincoln, Minneapolis and St. Paul, Madison and Milwaukee, St. Louis, Louisville, Lexington, Detroit, Cincinnati, Cleveland, Columbus, Tole ...

Kansas Dust Storm
Kansas () is a state in the Midwestern United States. Its capital is Topeka, and its largest city is Wichita. Kansas is a landlocked state bordered by Nebraska to the north; Missouri to the east; Oklahoma to the south; and Colorado to the west. Kansas is named after the Kansas River, which in turn was named after the Kansa Native Americans who lived along its banks. The tribe's name (natively ') is often said to mean "people of the (south) wind" although this was probably not the term's original meaning. For thousands of years, what is now Kansas was home to numerous and diverse Native American tribes. Tribes in the eastern part of the state generally lived in villages along the river valleys. Tribes in the western part of the state were semi-nomadic and hunted large herds of bison. The first Euro-American settlement in Kansas occurred in 1827 at Fort Leavenworth. The pace of settlement accelerated in the 1850s, in the midst of political wars over the slavery deb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
