Mesoanalysis of tornado cyclones and genesis of tornadoes on Kyushu Island, Japan during the passage of Typhoon 8019
This tornado event was selected for study because of the availability of detailed surface data allowing for the examination of the mesoscale flow fields near the tornadoes. Emphasis is placed on the detection of the tornado cyclones and description
An analysis of tornado days in Missouri for the period 1950-2002
Atmospheric dynamics ; Climate ; Cluster analysis ; Missouri ; Seasonal variability ; Spatial variation ; Time series ; Tornado ; United States of America
Tornado analysis using a tornado-day approach was made for the State of Missouri, and its climatic divisions, for the period 1950-2002. Although tornado days have not increased in Missouri, the NW Prairie climatic division recorded a statistically
significant decline in tornado days during that time period. Seasonal patterns in tornado days were examined for each of the 115 countries in Missouri using cluster analysis.
Unexpected meteorological extremes : the Limerick tornado of 1851
Cold front ; Historical geography ; Impact ; Ireland ; Meteorology ; Nineteenth Century ; Tornado ; Weather type
An analysis of contemporary documentary sources and meteorological observations show that a T4 tornado event occurred in Limerick during October 1851 ahead of a cold front in unstable air. The path of the tornado through the city is reconstructed
Spatial and temporal characteristics of tornado path direction
Atmospheric dynamics ; Natural hazards ; Perception ; Spatial variation ; Synoptic climatology ; Tornado ; United States of America
This study examines path directions for 6,194 tornadoes that occurred in the eastern two-thirds of the United States during the period 1980-2002. At the national scale, nearly 70 percent of tornadoes included in the study propagated from the west
, west-southwest, and southwest, with west-southwest being the highest frequency origin direction. Nevertheless, distinct seasonal and regional variations were found. The midtropospheric flow, convective typology, and synoptic patterns of tornado

The goal of this research is to determine the extent to which Virginia tornado events are characterized by different air-mass and air-flow characteristics. The AA. hypothesize that several distinctly different synoptic weather situations
are responsible for Virginia tornadoes and that the values of a suite of instability and severe-weather indices used for predicting tornadic activity are significantly different among these air-mass types.

Climatología ; Dinámica de la atmosfera ; Polonia ; Previsión ; Riesgo natural ; Tornado
This article assesses current possibilities in Poland where the forecasting of tornadoes is concerned. The A. reviews the literature related to tornado genesis, and the climatology of these phenomena in Poland. On the basis of current scientific
attainments, he then describes three methods that are used operationally in predicting tornadoes. On this basis, the A. defines four operational levels, which – depending on the particular product used – allow for the issuance of tornado forecasts or warnings
. The analysis shows that operational tornado forecasting in Poland takes place at the second and third levels, but that the accuracy and reliability of predictions and warnings is relatively low at this stage. – (BJ)
Capturing damage assessment with a spatial video : an example of a building and street-scale analysis of tornado-related mortality in Joplin, Missouri, 2011

The 27 April 2011 EF4 Tuscaloosa tornado directly impacted more than 50,000 residents, causing forty-five fatalities within the city and sixty-five in total. It was a rare urban tornado with varying impacts on the three major ethnic and racial
groups within the city. A hybrid survey and interview of open-ended and closed questions was conducted with 211 Tuscaloosa area residents in a two-week period after the tornado. Results indicate significant differences in risk perception, preparedness
Pedologic and geomorphic impacts of a tornado blowdown event in a mixed pine-hardwood forest

Two blowdown sites caused by a November 2005 tornado in the Ouachita National Forest, Arkansas, allowed a case study examination of bioturbation associated with a specific forest blowdown event, as well as detailed examination of relationships
Relationships between phases of the El Niño-Southern Oscillation and character of the tornado season in the South-Central United States

This study examines the spatial patterns of societal impacts associated with tornadoes and high winds with 31 inland-moving tropical cyclones (TC) that made landfall from 1985 to 2008. Hourly weather information was collected from all available
Center's Storm Data. Geographic Information System (GIS) software was employed to make geometric measurements of the distance and direction of the impacts relative to storm center. The majority of tropical cyclone tornado and high wind impacts occur
