Question

A tornado is “a violently rotating column of air, in contact with the ground, either pendant from a cumuliform cloud or underneath a cumuliform cloud, and often (but not always) visible as a funnel cloud”. For a vortex to be classified as a tornado, it must be in contact with both the ground and the cloud base. Scientists have not yet created a complete definition of the word; for example, there is disagreement as to whether separate touchdowns of the same funnel constitute separate tornadoes. Tornado refers to the vortex of wind, not the condensation cloud.

A tornado is not necessarily visible; however, the intense low pressure caused by the high, wind speeds (as described by Bernoulli’s principle) and rapid rotation (due to cyclostrophic balance) usually cause water vapor in the air to condense into cloud droplets due to adiabatic cooling. This results in the formation of a visible funnel cloud or condensation funnel.

There is some disagreement over the definition of a funnel cloud and a condensation funnel. According to the Glossary of meteorology, a funnel cloud is any rotating cloud pendant from a cumulus or cumulonimbus, and thus most tornadoes are included under this definition. Among many meteorologist, 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.

Tornadoes often begin as funnel clouds with no associated strong winds at the surface, and not all funnel clouds evolve into tornadoes. Most tornadoes produce strong winds at the surface while the visible funnel is still above the ground, so it is difficult to discern the difference between a funnel cloud and a tornado from a distance.

Where have experts observed tornados?

• There is no specific information in the text about the location of where experts have observed tornados, but in America, there is a location called "Tornado Alley" in central region where experts such as meteorologists and storm chasers often travel to the area in order to study about tornados and improve their understanding  of tornado formation and its behavior.

Di mana para ahli mengamati tornado?

• Tidak ada informasi khusus dalam teks tentang lokasi di mana para ahli mengamati tornado, tetapi di Amerika, ada lokasi yang disebut "Tornado Alley" di wilayah tengah di mana para ahli seperti ahli meteorologi dan pemburu badai sering bepergian ke daerah tersebut untuk mempelajari tentang tornado dan meningkatkan pemahaman mereka tentang pembentukan tornado dan perilakunya.
