" It is found that there is a positive correlation with observed occurrence and population density and radar locations. This paper seeks to remove the temporal variability and the biases in space due to the underreporting of tornado occurrence in a midwestern region. The resulting probability density function suggests an approximately 60% increase in the total likely number of tornado occurrence for a given year, as reflected in the increase in the average spatial probability density function."
"The average expected density of tornadoes
increased from 0.0341 per year per 100 km2 to 0.0550
per year per 100 km2."
