TORNADO FREQUENCY IN KANSAS

Metaphors and Mathematical Identity: Math is Like a Tornado in Kansas

Mathematical identity is an individual’s concept of who he or she is mathematically. In this paper, metaphors for mathematics from elementary education majors are compared to metaphors created by secondary mathematics teaching majors. The analysis demonstrates a basic difference in the mathematical identity of the two groups, with the latter group having more holistic conceptions of mathematics...

Detection of Tornado Frequency Trend Over Ontario, Canada

An upward trend in Ontario tornado frequency (about 1.6 tornadoes/decade with the statistically significant level at least at 95%) is identified using three independent approaches. The first method is the conventional linear regression method that had no disturbance to the original tornado time series. The second approach is to employ the Mann-Kendall test with consideration of removing a lag o...

Tornado Warnings and Tornado Fatalities : The Case of May 22 , 2011 Tornado in Joplin , Missouri

Influence of the El Niño/Southern Oscillation on tornado and hail frequency in the United States

The El Niño-Southern Oscillation (ENSO) is characterized by changes in sea surface temperature (SST) and atmospheric convection in the tropical Pacific, and modulates global weather and climate1–4. The phase of ENSO influences United States (US) temperature and precipitation and has long been hypothesized to influence severe thunderstorm occurrence over the US5–11. However, limitations12 of the...

Tornado Forecasting: A Review

Present-day operational tornado forecasting can be thought of in two parts: anticipation of tornadic potential in the storm environment, and recognition of tornadic storms once they develop. The former is a forecasting issue, while the latter is associated with warnings (or so-called nowcasting). This paper focuses on the forecasting aspect of tornadoes1, by dealing primarily with the relations...
