Barring a low-level boundary, tornadogenesis is highly unlikely unless a rear flank downdraft occurs, which is usually visibly evidenced by evaporation of cloud adjacent to a corner of a wall cloud. [21] Among many meteorologists, the 'funnel cloud' term is strictly defined as a rotating cloud which is not associated with strong winds at the surface, and condensation funnel is a broad term for any rotating cloud below a cumuliform cloud. North America is a large continent that extends from the tropics north into arctic areas, and has no major eastwest mountain range to block air flow between these two areas. Some meteorological situations leading to tornadogenesis are not readily detectable by radar and tornado development may occasionally take place more quickly than radar can complete a scan and send the batch of data. The climate-tornado link is confounded by the forces affecting larger patterns and by the local, nuanced nature of tornadoes.

[17] For a vortex to be classified as a tornado, it must be in contact with both the ground and the cloud base. While there is a large drop in atmospheric pressure inside a strong tornado, the pressure difference is unlikely to cause significant damage.
