We intend to investigate tornadoes, their frequency and magnitude in the last 50 years, and examine how that relates to climate data in two different regions. We will select one region which historically has experienced high tornado activity, and another which has not seen many tornadoes. It is also our intent to become familiar with the conditions favorable to tornado formation, as well as the inner workings of the storms and tornadoes themselves. Our research of tornadoes and climate data for the two regions should allow us to determine if there is a correlation between that data and the frequency and magnitude of the regionÍs tornadoes in the last 50 years. Our data will be downloaded from NOAA.
From preliminary research, we have found that tornado activity in the United States has increased significantly since the middle of the 20th century. We believe that this increase is related to an increase in global temperatures. This may also be attributed to better reporting and an improvement in detection technology. We also hypothesize that our designated tornado ïhot spotÍ will have seen an increase in the frequency and magnitude of tornadoes, and that our ïquiet areaÍ will not see much of an increase. These areas to be determined later, after more research.
We will utilize statistics to compare data and regions. This will enable us to found out if the differences are statistically significant. All of our data will be entered into StatView.
