Every year tornadoes become more prevalent and massive? Source?
- Someone 13y agoNo. Source: http://www.spc.noaa.gov/publications/mccarthy/tor30yrs.pdf http://www.spc.noaa.gov/publications/mccarthy/tor30yrs.pdf: Finally, it will be seen that the number of strong and violent tornadoes has not varied much since 1970, and that long-track and very-long-track tornadoes as defined by the Illinois State Water Survey remain a very low percentage of all tornadoes reported. [...] The increase in reported tornado frequency during the early 1990s corresponds to the operational implementation of Doppler weather radars. Other non- meteorological factors that must be considered when looking at the increase in reported tornado frequency over the past 33 years are the advent of cellular telephones; the development of spotter networks by NWS offices, local emergency management officials, and local media; and population shifts.
