Severe Weather in March

Posted: 03 Mar 2011 05:57 AM

The numbers on the featured plot show the yearly average March temperature for Iowa. The location of the number represents the spatial center of mass for all the severe thunderstorm and tornado warnings issued for March during that year. The map is attempting to show the relationship between average temperature in Iowa to the favoured are to where severe weather happens. The warmest temperatures mostly appear to the west and north in this map, which makes some logical sense as warmer weather would promote severe weather further north near Iowa. The coldest temperatures imply that severe weather is pushed to the south away from the state. The limited area of this plot also suggests that most of the severe weather happens in this area during March.
