Tornado Outbreak Of April 1977
A violent severe weather outbreak struck the Southeast on April 4–5, 1977. A total of 22 tornadoes touched down with the strongest ones occurring in Mississippi, Alabama, and Georgia. The strongest was a catastrophic F5 tornado that struck the northern Birmingham, Alabama, suburbs during the afternoon of Monday, April 4. In addition to this tornado, several other tornadoes were reported from the same system in the Midwest, Alabama, Georgia, Mississippi and North Carolina. One tornado in Floyd County, Georgia, killed one person, and another fatality was reported east of Birmingham in St. Clair County. In the end, the entire outbreak directly caused 24 deaths and 158 injuries. The storm system also caused the crash of Southern Airways Flight 242, which killed 72 and injured 22. Outbreak statistics Confirmed tornadoes Prior to 1990, there is a likely undercount of tornadoes, particularly E/F0–1, with reports of weaker tornadoes becoming m ...

Tornadoes Of 1977
This page documents the tornadoes and tornado outbreaks of 1977, primarily in the United States. Most tornadoes form in the U.S., although some events may take place internationally. Tornado statistics for older years like this often appear significantly lower than modern years due to fewer reports or confirmed tornadoes. Synopsis Numbers for 1977 were below average, both in terms of number of tornadoes and number of fatalities; however, there were over 700 injuries related to tornadoes. Events January 5 tornadoes were reported in the U.S. in January. February 17 tornadoes were reported in the U.S. in February. March 64 tornadoes were reported in the U.S. in March. March 28 A small, widespread tornado outbreak caused an F2 tornado to strike the University of Southern Mississippi in Hattiesburg, Mississippi. Another F2 struck the downtown area of Lafayette, Louisiana. An F3 struck 5 to 10 houses northwest of Camden, Mississippi. Overall, there were only 10 injures, but no ...

Southern Airways Flight 242
Southern Airways Flight 242 was a flight from Muscle Shoals, Alabama, to Atlanta, Georgia, with a stop in Huntsville, Alabama. On April 4, 1977, it executed a forced landing on Georgia State Route 381 in New Hope, Paulding County, Georgia, United States, after suffering hail damage and losing thrust on both engines in a severe thunderstorm.

Headquartered at the National Weather Center in Norman, Oklahoma, the Storm Prediction Center is tasked with forecasting the risk of severe thunderstorms and tornadoes in the contiguous United States. It issues #Convective outlooks, convective outlooks, #Mesoscale discussions, mesoscale discussions, and #Weather watches, watches as a part of this process. Convective outlooks are issued for the following eight days (issued separately for Day 1, Day 2, Day 3, and Days 4–8), and detail the risk of severe thunderstorms and tornadoes during the given forecast period, although tornado, hail and wind details are only available for Days 1 an ...

Weather Radar
A weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation (meteorology), precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.). Modern weather radars are mostly pulse-Doppler radars, capable of detecting the motion of rain droplets in addition to the intensity of the precipitation. Both types of data can be analyzed to determine the structure of storms and their potential to cause severe weather. During Radar in World War II, World War II, radar operators discovered that weather was causing echoes on their screens, masking potential enemy targets. Techniques were developed to filter them, but scientists began to study the phenomenon. Soon after the war, military surplus, surplus radars were used to detect precipitation. Since then, weather radar has evolved and is used by national weather services, research departments in universities, and in television stations' weather d ...

Tornado And Storm Research Organisation
The Tornado and Storm Research Organisation (TORRO) was founded by Terence Meaden in 1974. Originally called the Tornado Research Organisation, it was expanded in 1982 following the inclusion of the Thunderstorm Census Organisation (TCO) after the death of its founder Morris Bower and his wife. The current Head of TORRO is Paul Knightley, a professional meteorologist. TORRO comprises nearly 400 members in the United Kingdom and others from around the world, from amateurs to professional meteorologists, and almost 30 staff. TORRO maintains a large storm spotter network throughout the British Isles and collects and records reports of severe weather. TORRO carries out research on many aspects of severe weather including ball lightning, blizzards & heavy snowfall, coastal impacts, hailstorms, lightning impacts, tornadoes, thunderstorms, weather disasters, and weather & health. Tornadoes in the UK are classified using the T-scale. TORRO has also developed a hailstorm intensity scale. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
TORRO Scale
The TORRO tornado intensity scale (or T-Scale) is a scale measuring tornado intensity between T0 and T11. It was proposed by Terence Meaden of the Tornado and Storm Research Organisation (TORRO), a meteorological organisation in the United Kingdom, as an extension of the Beaufort scale. History and derivation from Beaufort scale The scale was tested from 1972 to 1975 and was made public at a meeting of the Royal Meteorological Society in 1975. The scale sets T0 as the equivalent of 8 on the Beaufort scale and is related to the Beaufort scale (B), up to 12 on the Beaufort scale, by the formula: : ''B'' = 2 (''T'' + 4) and conversely: : ''T'' = ''B''/2 - 4 The Beaufort scale was first introduced in 1805, and in 1921 quantified. It expresses the wind speed as faster than v in the formula: : v = 0.837 ''B''3/2 m/s TORRO scale formula Most UK tornadoes are T6 or below with the strongest known UK tornado estimated as a T9 (the 1666 Lincolnshire tornado).
