The OTEA, derived by the work of USTornadoes and Cameron Nixon, aims to archive environmental soundings from significant* tornadic storms that formed in the province of Ontario from 1953 - 2021. All soundings pulled are sourced from NARR (North American Regional Reanalysis) model data during - or closest to - when a storm was in its mature stage.

​

Since similar enviromental conditions produce similar storms, we hope this servers as a valuable tool to aid forecasters in their efforts of predicting both severe and tornadic weather events - increasing lead times and, in turn, saving lives/property in the process.
