NARRATOR:

They are sometimes seen as threatening funnel clouds descending from stormy skies. Others can be nearly invisible, like a ghostly spiral of wind skimming the sea surface. These eerie columns of rotating air are known as waterspouts — commonly defined as tornadoes over water.

Waterspouts usually develop over warm tropical ocean waters. They're spotted in the Florida Keys more than any other place in the world. They've also been seen over the waters of the Great Lakes. Scientists that study waterspouts generally put them in two categories: fair weather and tornadic.

The tornadic waterspouts may often begin as tornadoes over land and then move over water. They also form in severe thunderstorms over a body of water. They can wreak havoc with high winds, hail, and dangerous lightning.

Fair weather waterspouts develop in calmer weather. They form only over open water, developing at the surface and actually climbing skyward towards the clouds. The size of all waterspouts can range from just a few feet, to several hundred feet wide. Research shows that fair weather waterspouts exhibit a five-stage life cycle:

Stage 1 is the formation of a disk on the surface of the water, known as a dark spot; Stage 2 is a spiral pattern on the water surface; Stage 3 is a formation of a spray ring; Stage 4 is where the waterspout becomes a visible funnel; and the lifecycle ends with Stage 5 - where the waterspout decays.

Like many forces in nature, waterspouts can be both beautiful and dangerous. They've been known to overturn boats, damage large ships, and put lives in jeopardy. If you spot one, exercise extreme caution and keep your distance. Don't leave your safety up in the air – try to avoid these turbulent twisters.

NARRADOR:

Se observan a veces como nubes amenazantes en forma de embudo que descienden de los cielos tormentosos. Otras pueden ser casi invisibles, como un espiral fantasmal de viento rozando la superficie del mar.

Estas columnas misteriosas de aire rotativo se conocen como trombas marinas, comúnmente definidas como tornados sobre el agua.

Las trombas marinas generalmente se desarrollan en las cálidas aguas tropicales oceánicas. Son vistas en los Cayos de la Florida más que cualquier otro lugar en el mundo. También han sido vistas sobre las aguas de los Grandes Lagos.

Los científicos que las estudian por lo general las clasifican en dos categorías: tornádicas y no tornádicas.

Las trombas marinas tornádicas a menudo comienzan como tornados sobre la tierra y luego se mueven hacia el agua. También se forman en tormentas severas sobre un cuerpo de agua. Pueden hacer estragos con fuertes vientos, granizo y rayos peligrosos.

Las trombas marinas no tornádicas se desarrollan en un clima más tranquilo. Estas solo se forman en aguas abiertas, desarrollándose en la superficie y, de hecho escalan hacia el cielo, a las nubes.

El tamaño de las trombas marinas puede variar desde unos pocos metros a varios cientos, de ancho.

Las investigaciones muestran que las trombas marinas no tornádicas presentan un ciclo de vida de cinco etapas:

La etapa 1 es la formación de un disco en la superficie del agua, conocida como una mancha oscura; La etapa 2 es un patrón en espiral sobre la superficie del agua; La etapa 3 es la formación de un anillo de aspersión; La etapa 4 es donde la tromba se convierte en un embudo visible; y el ciclo de vida termina con la etapa 5, donde la tromba se desintegra.

Al igual que muchas fuerzas de la naturaleza, las trombas marinas pueden ser a la vez bellas y peligrosas. Han sido conocidas por voltear embarcaciones, dañar grandes barcos, y poner vidas en peligro. Si se encuentra con una, extreme precauciones y mantenga su distancia. No deje su seguridad al aire, trate de evitar estos turbulentos remolinos.
