Alan Moller
Alan Roger Moller (February 1, 1950 – June 19, 2014) was an American meteorologist, storm chaser, nature and landscape photographer known for advancing Storm spotting, spotter training and bridging operational meteorology (particularly severe storms Weather forecasting, forecasting) with research. Early years Moller was born in Fort Worth, Texas on February 1, 1950, grew up in the South Hills section of Fort Worth, and attended R. L. Paschal High School. He studied meteorology at the University of Oklahoma (OU) where he earned B.S. and M.S. degrees in the late 1960s and early 1970s.

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] |

Blues
Blues is a music genre and musical form which originated in the Deep South of the United States around the 1860s. Blues incorporated spirituals, work songs, field hollers, shouts, chants, and rhymed simple narrative ballads from the African-American culture. The blues form is ubiquitous in jazz, rhythm and blues, and rock and roll, and is characterized by the call-and-response pattern (the blues scale and specific chord progressions) of which the twelve-bar blues is the most common. Blue notes (or "worried notes"), usually thirds, fifths or sevenths flattened in pitch, are also an essential part of the sound. Blues shuffles or walking bass reinforce the trance-like rhythm and form a repetitive effect known as the groove. Blues as a genre is also characterized by its lyrics, bass lines, and instrumentation. Early traditional blues verses consisted of a single line repeated four times. It was only in the first decades of the 20th century that the most common current str ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbecue In The United States
In the United States, barbecue refers to a technique of cooking meat outdoors over a fire; often this is called pit barbecue, and the facility for cooking it is the barbecue pit. This form of cooking adds a distinctive smoky taste to the meat; barbecue sauce, while a common accompaniment, is not required for many styles. In the South, barbecue is more than just a style of cooking, but a subculture with wide variation between regions, and fierce rivalry for titles at barbecue competitions. Often the proprietors of Southern-style barbecue establishments in other areas originate from the South. Description There are usually three ingredients to barbecue—meat and wood smoke are essential. The use of a sauce or seasoning varies widely between regional traditions. The first ingredient in the barbecue tradition is the meat. The most widely used meat in most barbecue is pork, particularly pork ribs, and also the pork shoulder for pulled pork. (In Texas, beef is more common, especi ...

Drag Racing
Drag racing is a type of motor racing in which automobiles or motorcycles compete, usually two at a time, to be first to cross a set finish line. The race follows a short, straight course from a standing start over a measured distance, most commonly , with a shorter, distance becoming increasingly popular, as it has become the standard for Top Fuel dragsters and Funny Cars, where some major bracket races and other sanctioning bodies have adopted it as the standard. The is also popular in some circles. Electronic timing and speed sensing systems have been used to record race results since the 1960s. The history of automobiles and motorcycles being used for drag racing is nearly as long as the history of motorized vehicles themselves, and has taken the form of both illegal street racing and as a regulated motorsport. History Drag racing started in the 1940s. World War II veterans were prominently involved, and some early drag races were done at decommissioned aircraft b ...

Early-onset Alzheimer's Disease
Early-onset Alzheimer's disease, also called younger-onset Alzheimer's, is Alzheimer's disease diagnosed before the age of 65. It is an uncommon form of Alzheimer's, accounting for only 5–10% of all Alzheimer's cases. About 60% have a positive family history of Alzheimer's and 13% of them are inherited in an autosomal dominant manner. Most cases of early-onset Alzheimer's share the same traits as the "late-onset" form and are not caused by known genetic mutations. Little is understood about how it starts. Non-familial early-onset AD can develop in people who are in their 30s or 40s, but this is extremely rare, and mostly people in their 50s or early 60s are affected. Familial Alzheimer's disease Alzheimer's disease (AD) is a neurodegenerative disease and the most common cause of dementia; it usually occurs in old age. Familial Alzheimer's disease is an inherited and uncommon form of AD. Familiar AD usually strikes earlier in life, defined as before the age of 65. FAD usually im ...

Storm Track (magazine)
''Storm Track'' was the first magazine for and about storm chasing. The magazine was in circulation between 1977 and 2002. History and profile ''Storm Track'' was started in 1977 by chasing pioneer David Hoadley following an informal meeting of storm chasers at an American Meteorological Society conference. In the beginning, it was published in newsletter format in Falls Church, Virginia, but in time assumed a magazine format and was published bimonthly throughout its history. In 1986, editorship was handed over to Tim Marshall, a storm damage engineer (and meteorologist).

VORTEX Projects
The Verification of the Origins of Rotation in Tornadoes Experiment (or VORTEX) are field experiments that study tornadoes. VORTEX1 was the first time scientists completely researched the entire evolution of a tornado with an array of instrumentation, enabling a greater understanding of the processes involved with tornadogenesis. A violent tornado near Union City, Oklahoma was documented in its entirety by chasers of the Tornado Intercept Project (TIP) in 1973. Their visual observations led to advancement in understanding of tornado structure and life cycles. VORTEX2 used enhanced technology that allowed scientists to improve forecasting capabilities and improve lead time on advanced warnings to residents. VORTEX2 sought to reveal how tornadoes form, how long they last and why they last that long, and what causes them to dissipate. VORTEX1 and VORTEX2 was based on the use of large fleets of instrumented vehicles that ran on land, as well as aircraft and mobile radars. Important wo ...
