What is a Waterspout? Persons living in northern Michigan are well aware that the Great Lakes have a profound impact on local weather patterns. Examples include heavy lake effect snows in winter, and cooling lake breezes in summer.
As the end of the summer season approaches, another type of unique Great Lakes weather phenomena is possible Water spouts the waterspout. The following photo is of a waterspout over the Great Lakes.
Joseph Golden, a distinguished waterspout authority with the National Oceanic and Atmospheric Administration NOAAdefines the waterspout as a "funnel which contains an intense vortex, sometimes destructive, of small horizontal extent and which occurs over a body of water.
The fact is, depending on how they form, waterspouts come in two types: Tornadic waterspouts generally begin as true tornadoes over land in association with a thunderstorm, and then move out over the water. They can be large and are capable of considerable destruction.
Fair weather waterspouts, on the other hand, form only over open water. They develop at the surface of the water and climb skyward in association with warm water temperatures and high humidity in the lowest several thousand feet of the atmosphere.
They are usually small, relatively brief, and less dangerous. The fair weather variety of waterspout is much more common than the tornadic.
Waterspouts occur most frequently in northern Michigan during the months of August, September, and October, when the waters of the Great Lakes are near their warmest levels of the year. Waterspout formation typically occurs when cold air moves across the Great Lakes and results in large temperature differences between the warm water and the overriding cold air.
They tend to last from about two to twenty minutes, and move along at speeds of 10 to 15 knots. Joseph Golden distinguishes five stages of waterspout formation: A prominent circular, light-colored disk appears on the surface of the water, surrounded by a larger dark area of indeterminate shape and with diffused edges.
A pattern of light and dark-colored surface bands spiraling out from the dark spot which develops on the water surface. A dense swirling annulus ring of sea spray, called a cascade, appears around the dark spot with what appears to be an eye similar to that seen in hurricanes. The waterspout, now visible from water surface to the overhead cloud mass, achieves maximum organization and intensity.
Its funnel often appears hollow, with a surrounding shell of turbulent condensate.At least four water spouts were reported Wednesday along the Florida Gulf Coast. Jun 25, · Waterspouts fall into two categories: fair weather waterspouts and tornadic waterspouts. Tornadic waterspouts are tornadoes that form over water, or move from land to water.
They have the same characteristics as a land tornado. They are associated with severe thunderstorms, and are often accompanied by high winds and seas, large hail, and frequent dangerous lightning. The lower Florida Keys report more waterspout activity than any other location in the world, and Florida is considered to be the waterspout capital of the U.S.
The words fair weather and waterspout may seem like a contradiction, but most waterspouts form during periods of mild to warm sunny. Watersprouts appear as strange, out of character growth from the older branches of a tree (usually) or large shrub. They tend to grow fast, often uncannily vertically, sometimes in clusters at a single point.
Removing them is a typical no-brainer pruning task.
On extreme occasions, a few of these vortices may stretch all the way up to the clouds above, creating the elusive winter waterspout. — matthew cappucci, Washington Post, "It’s been ‘wicked cold’ in Boston for over a week, and . A waterspout is an intense columnar vortex (usually appearing as a funnel-shaped cloud) that occurs over a body of grupobittia.com are connected to a cumulus congestus cloud, some to a cumuliform cloud and some to a cumulonimbus cloud. In the common form, it is a non-supercell tornado over grupobittia.com it is often weaker than most of its land counterparts, stronger versions spawned by mesocyclones. A waterspout is a column of rotating, cloud-filled wind. A waterspout descends from a cumulus cloud to an ocean or a lake.
You can think of watersprouts as. Waterspouts are similar to tornadoes over water. Waterspouts are generally broken into two categories: fair weather waterspouts and tornadic waterspouts.
Tornadic waterspouts are simply tornadoes that form over water, or move from land to water.
They have the same characteristics as a land tornado. Waterspouts. By Bruce B. Smith, Meteorologist, NWS Gaylord. 1. What is a Waterspout?
