  • More Observations of Small Funnel Clouds and Other Tubular Clouds
    3714 MONTHLY WEATHER REVIEW VOLUME 133 PICTURE OF THE MONTH More Observations of Small Funnel Clouds and Other Tubular Clouds HOWARD B. BLUESTEIN School of Meteorology, University of Oklahoma, Norman, Oklahoma (Manuscript received 14 March 2005, in final form 20 May 2005) ABSTRACT In this brief contribution, photographic documentation is provided of a variety of small, tubular-shaped clouds and of a small funnel cloud pendant from a convective cloud that appears to have been modified by flow over high-altitude mountains in northeast Colorado. These funnel clouds are contrasted with others that have been documented, including those pendant from high-based cumulus clouds in the plains of the United States. It is suggested that the mountain funnel cloud is unique in that flow over high terrain is probably responsible for its existence; other types of small funnel clouds are seen both over elevated, mountainous terrain and over flat terrain at lower elevations. 1.

  • Tim Samaras 1957 – 2013 Nyheden Om Tim Samaras Alt for Tidlige Og Uforståelige Bortgang Skabte Chokbølger I Det Amerikanske
    Tim Samaras 1957 – 2013 Nyheden om Tim Samaras alt for tidlige og uforståelige bortgang skabte chokbølger i det amerikanske meteorologiske miljø og blandt stormchasere verden over i dagene efter 1. Juni 2013. Tim Samaras interesse for tornadoer blev vakt i en alder af 6, da hans forældre tvang ham til at se ”Troldmanden fra Oz”. Som ung uddannede han sig til ingeniør. Hans interesse for tornadoer voksede og hans stiftede team TWISTEX (Tactical Weather Instrumented Sampling in/near Tornadoes Experiment) hvis mål var at foretage in situ målinger af temperatur, tryk m.m. i tornadoer. Han designede og byggede selv sine instrumenter, bl.a. sine tornadoprober (”Skilpadder” med måleudstyr og kameraer) som blev placeret direkte i en tornados bane. Han udstyr er indehaver af et rekordstort registreret trykfald på 100 hPa i en tornado. Trykfaldet skete på under et minut, og det laveste tryk var 850 hPa – hvilket også er det lavest registrerede lufttryk ved jordoverfladen når der er kalibreret for højden over havet. Denne måling blev foretaget i forbindelse med Manchester, South Dakota tornadoen i 2003. Tim Samaras anden store passion var lyn. Han ombyggede et koldkrigs highspeed kamera, oprindeligt til fotografering af nukleare eksplosioner med konventionel film, til digital fotografering med over 1.000.000 billeder i sekundet og har med det kunnet registrere et lyns livscyklus med hidtil usete detaljer. Tim Samaras og hans crew blev verdenskendt og respekteret for deres deltagelse i 3 sæsoner af Discovery Channels’s serie ”Storm Chasers”. Tim Samaras var også primus motor på det årlige National Storm Chasers Convention, som en weekend i februar i Denver tiltrækker stormchasere fra hele verden.

National Oceanic and Atmospheric Administration (NOAA) National Severe Storms Laboratory (NSSL), Norman, Oklahoma, USA ABSTRACT: On 31 May 2013, a line of severe thunderstorms developed during the local afternoon in central Oklahoma, USA. One of the supercells produced the El Reno tornado, which caused significant damage and killed several people. During the 2300 UTC hour (during the mature supercell stage and just after the tornado began), the storm produced several positive cloud-to-ground (+CG) lightning strokes that featured large (> 100 C km) impulse charge moment changes (iCMCs; charge moment during the first 2 ms after the return stroke). These discharges occurred mainly in convection, in contrast to the typical pattern of large-CMC and sprite-parent +CGs occurring mainly in stratiform precipitation regions. After this time, the line of thunderstorms evolved over several hours into a large mesoscale convective system (MCS). By the 0700 UTC hour on 1 June 2013, the large-CMC pattern had changed markedly. Large-CMC negative CGs, which were absent early in the storm's lifetime, occurred frequently within convection.

  • Use of the European Severe Weather Database to Verify Satellite-Based Storm Detection Or Nowcasting
    USE OF THE EUROPEAN SEVERE WEATHER DATABASE TO VERIFY SATELLITE-BASED STORM DETECTION OR NOWCASTING Nikolai Dotzek1,2, Caroline Forster1 1 Deutsches Zentrum für Luft- und Raumfahrt (DLR), Institut für Physik der Atmosphäre, Oberpfaffenhofen, 82234 Wessling, Germany 2 European Severe Storms Laboratory, Münchner Str. 20, 82234 Wessling, Germany Abstract Severe thunderstorms constitute a major weather hazard in Europe, with an estimated total damage of € 5-8 billion each year. Yet a pan-European database of severe weather reports in a homogeneous data format has become available only recently: the European Severe Weather Database (ESWD). We demonstrate the large potential of ESWD applications for storm detection and forecast or now- casting/warning verification purposes. The study of five warm-season severe weather days in Europe from 2007 and 2008 revealed that up to 47% of the ESWD reports were located exactly within the polygons detected by the Cb-TRAM algorithm for three different stages of deep moist convection. The cool-season case study of extratropical cyclone “Emma” on 1 March 2008 showed that low-topped winter thunderstorms can provide a challenge for satellite storm detection and nowcasting adapted to warm-season storms with high, cold cloud tops. However, this case also demonstrated how ESWD reports alone can still be valuable to identify the hazardous regions along the cold front of the cyclone. 1. INTRODUCTION Severe thunderstorms, with their attendant strong winds, hail, flooding, and tornadoes, are common phenomena in many European countries, leading to a total damage estimate of 5 to 8 billion euros per year (source: Munich Re Group). Extreme events like an F4 tornado in France and an F3 downburst in Austria in 2008 exemplify these damage totals.

  • Glossary of Severe Weather Terms
    Glossary of Severe Weather Terms -A- Anvil The flat, spreading top of a cloud, often shaped like an anvil. Thunderstorm anvils may spread hundreds of miles downwind from the thunderstorm itself, and sometimes may spread upwind. Anvil Dome A large overshooting top or penetrating top. -B- Back-building Thunderstorm A thunderstorm in which new development takes place on the upwind side (usually the west or southwest side), such that the storm seems to remain stationary or propagate in a backward direction. Back-sheared Anvil [Slang], a thunderstorm anvil which spreads upwind, against the flow aloft. A back-sheared anvil often implies a very strong updraft and a high severe weather potential. Beaver ('s) Tail [Slang], a particular type of inflow band with a relatively broad, flat appearance suggestive of a beaver's tail. It is attached to a supercell's general updraft and is oriented roughly parallel to the pseudo-warm front, i.e., usually east to west or southeast to northwest. As with any inflow band, cloud elements move toward the updraft, i.e., toward the west or northwest. Its size and shape change as the strength of the inflow changes. Spotters should note the distinction between a beaver tail and a tail cloud. A "true" tail cloud typically is attached to the wall cloud and has a cloud base at about the same level as the wall cloud itself. A beaver tail, on the other hand, is not attached to the wall cloud and has a cloud base at about the same height as the updraft base (which by definition is higher than the wall cloud).

  • NOTES and CORRESPONDENCE a Funnel Cloud in a Convective
    2786 MONTHLY WEATHER REVIEW VOLUME 136 NOTES AND CORRESPONDENCE A Funnel Cloud in a Convective Cloud Line to the Rear of a Surface Cold Front HOWARD B. BLUESTEIN School of Meteorology, University of Oklahoma, Norman, Oklahoma (Manuscript received 24 August 2007, in final form 28 November 2008) ABSTRACT This brief case study describes the unusually benign environment in which a funnel cloud formed along a line of convective towers during the summer in Kansas. The parent cloud line was solitary and very narrow, yet organized on the mesoscale. The cloud line appeared to be best correlated with a zone of horizontal temperature gradient to the northwest of cool (evaporatively produced) outflow from an area of precipitation located just to the rear of a cold front. Implications for forecasting such an event are noted. 1. Introduction common.

  • Tornadoes – Forecasting, Dynamics and Genesis
    Tornadoes – forecasting, dynamics and genesis Mteor 417 – Iowa State University – Week 12 Bill Gallus Tools to diagnose severe weather risks • Definition of tornado: A vortex (rapidly rotating column of air) associated with moist convection that is intense enough to do damage at the ground. • Note: Funnel cloud is merely a cloud formed by the drop of pressure inside the vortex. It is not needed for a tornado, but usually is present in all but fairly dry areas. • Intensity Scale: Enhanced Fujita scale since 2007: • EF0 Weak 65-85 mph (broken tree branches) • EF1 Weak 86-110 mph (trees snapped, windows broken) • EF2 Strong 111-135 mph (uprooted trees, weak structures destroyed) • EF3 Strong 136-165 mph (walls stripped off buildings) • EF4 Violent 166-200 mph (frame homes destroyed) • EF5 Violent > 200 mph (steel reinforced buildings have major damage) Supercell vs QLCS • It has been estimated that 60% of tornadoes come from supercells, with 40% from QLCS systems. • Instead of treating these differently, we will concentrate on mesocyclonic versus non- mesocyclonic tornadoes • Supercells almost always produce tornadoes from mesocyclones. For QLCS events, it is harder to say what is happening –they may end up with mesocyclones playing a role, but usually these are much shorter lived. Tornadoes - Mesocyclone-induced a) Usually occur within rotating supercells b) vertical wind shear leads to horizontal vorticity which is tilted by the updraft to produce storm rotation, which is stretched by the updraft into a mesocyclone with scales of a few

  • El Reno Tornado (May 31 2013)
    Online Summary Damage from the 31 May 2013 Tornado in El Reno, OK (Image Courtesy of http://www.weather.com/news/tornado-central/storm-damage-friday-20130531) University of Florida Wind Hazard Damage Assessment Team PI: David O. Prevatt, Ph.D., PE [email protected] Contributing Authors: Jeandona Doreste Alyssa Egnew June 6, 2013 Wind Hazard Damage Assessment Team Engineering School of Sustainable Infrastructure and Environment University of Florida June 6, 2013 Executive Summary Just two weeks after a tornado caused extensive damage to Moore, OK, on 31 May 2013, El Reno, OK, was hit by another powerful tornado. El Reno is a little less than 30 miles to the north-west of Moore, and it has a population of 17,510 in 6,752 homes. The tornado tracked through mainly rural areas south of the town itself (south of Interstate 40). The unsettled weather spawned multiple vortices and several (nine) tornadoes in El Reno, Yukon, Mustang, near Moore, Del City, Watova and Oklahoma City. The most deadly was the El Reno. NWS reports a 16.2-mile curvilinear path of the tornado, and a maximum damage swath of 2.6 miles, making it the widest tornado on record. Building damage was relatively limited due to the rural track taken by this tornado. There were 20 confirmed fatalities, including the three storm chasers, Tim Samaras, his son, Paul and a videographer with his team. This was indeed a tragic loss to forecasting community. This report was prepared from online sources by University of Florida civil engineering students in Prof.
