American Geophysical Union experts available to comment on science of tornadoes

A tornado near Anadarko, Oklahoma. The lower part of this tornado is surrounded by a translucent dust cloud, kicked up by the tornado’s strong winds at the surface. The wind of the tornado has a much wider radius than the funnel itself.

Tornadoes occur in North America, South America, Southern Africa, Europe, Australia and New Zealand. More tornadoes occur in the United States than anywhere else in the world.

Meteorologists can detect tornadoes before or as they occur. Several American Geophysical Union scientists are available to comment on the science of tornadoes, including tornado formation, forecasting, warning systems, hazards and damage mitigation.

John Allen is an assistant professor of meteorology at Central Michigan University in Mount Pleasant, Michigan. His expertise is on the connections between large scale climate change and variability and severe thunderstorm phenomena like hail and tornadoes. He studies various aspects of that relationship, the historical records of tornadoes and hail both in the United States and globally, and whether scientists can predict tornado and hail seasonal activity in advance.
