Everything you need to know about water hoses

Have you ever seen water hoses? These "funnels," which emerge from Cumulonimbus clouds, can be surprising, especially if they form while sailing at sea. This intriguing and fascinating meteorological phenomenon is also known as a waterspout and is characterized by its ability to cover great distances and its ephemeral nature. In this article, we'll explore in detail how waterspouts form, their types, locations, and the impact they can have on the environment and human activities.

Types of water sleeves

Waterspouts can be classified into two distinct types:

• Tornadics: These are, as their name suggests, tornadoes that form over water. For them to appear, a severe thunderstorm, usually originating from a supercell, is essential. Although they are rare, their danger is high, as they can produce winds of up to 512 km/hThese winds can cause significant damage to nearby vessels and structures.
• Non-tornadic: These water sleeves usually form beneath the base of Cumulus or Cumulonimbus clouds. Although they do not pose as high a risk as tornadic sleeves, it is essential to stay away, since winds can reach speeds of 116 km/h.

Where are they formed?

Water sleeves are particularly common in tropical zones, such as the southeastern coast of the United States, as well as southern Florida and the Keys. They can also be observed in temperate climates, although they are less frequent. A good example occurred on April 13, 2016, in Galicia, Spain, where a waterspout made landfall on Cabío Beach in A Pobra do Caramiñal, causing significant damage to a bar.

Damage the hoses can cause

These phenomena can cause serious damage. They can affect ships, boats and people on the coast.Even if you live in an area where waterspouts are rare, it's advisable to avoid the beach during a storm, as danger can be imminent. Waterspouts, although less destructive than land-based tornadoes, can create violent waves and winds capable of capsizing small boats.

Formation of water sleeves

The formation of a waterspout is a complex meteorological process involving a series of stages. Generally, five phases can be distinguished in the life cycle of a waterspout:

1. Dark spot: The first sign of a developing waterspout is the appearance of a dark spot on the water's surface, indicating areas of low pressure that mark the beginning of air rotation.
2. Spiral pattern: As the rotation increases, a visible spiral pattern is generated on the water surface, alternating between light and dark areas.
3. Dew ring: This phase is characterized by the appearance of a dense ring of water spray around the dark spot, indicating that the vortex is strengthening.
4. Mature vortex: At this stage, the funnel extends from the water surface to the cumulus cloud, acquiring an organized and visible shape that can reach considerable altitudes.
5. Decay: When the warm air flow that feeds the waterspout dries up, it begins to weaken and gradually disappears.

Conditions for the formation of marine sleeves

For a waterspout to form, certain atmospheric conditions must coincide:

• Warm water temperatures: It is crucial that the water is warm enough to create a significant contrast with the cooler air above, creating the necessary instability in the atmosphere.
• High humidity: Humidity in the lower layers of the atmosphere is essential for promoting condensation and the appearance of the visible funnel. A warm and humid environment contributes to strengthening the vortex.
• Light winds at low levels: Gentle winds in the lower layers of the atmosphere help stabilize the waterspout, facilitating its formation and slowing the funnel's movement.

These combined factors allow the formation of water spouts, both on days of relative calm and during intense storms, creating opposite faces of the same phenomenon.

Forecasting and detection of marine swells

Weather services, such as the U.S. National Weather Service (NWS), use tools such as the doppler radar and other detection methods to predict the formation of slicks. They analyze environmental conditions, such as water temperature and humidity, and issue alerts when conditions are favorable.

In addition, it has been studied that the meteorological observatory in various regions is expanding its knowledge on the formation of similar phenomena, such as the case of the acid rain from a volcano, relevant to better understand the conditions that allow extreme weather events to occur.

Dangers and precautions

Although many waterspouts are relatively weak, both fair-weather and tornadic waterspouts can be dangerous for navigation and for people on the water. The greatest risk lies in the ability of waterspouts to surprise small boats, which can be capsized by the strong winds and waves they generate.

A tornadic waterspout approaching land can become a tornado upon reaching the coast, although its intensity generally diminishes quickly. However, anyone in the vicinity is advised to seek shelter, as even the weakest waterspouts can cause damage if they reach populated areas.

Impact on wildlife and the environment

The marine sleeves, thanks to their powerful winds, can lift small aquatic creatures, such as fish and frogs, to great heights, resulting in unusual phenomena known as “rain of fish”These events, although unusual, demonstrate the ability of waterspouts to affect not only the maritime environment but also the terrestrial environment, transporting living beings for considerable distances before they return to land.

This meteorological phenomenon is found in a wide range of natural phenomena that affect the environment, similar to what happens in the Arctic Ocean, where climatic conditions impact the region's biodiversity.

Sea sleeves and curiosities

Storm surges are just one of the impressive array of weather phenomena that the oceans can produce. This phenomenon not only leaves a lasting impression on those who have the opportunity to witness it, but is also associated with other extreme weather events. Both represent the power and beauty of nature, reminding us of the importance of respecting and understanding our environment.

Each waterspout is unique and can be considered a reminder of the power of atmospheric forces. Observers and scientists continue to study this phenomenon, intrigued by its unpredictability and its potential to provide insight into future climate conditions. With each waterspout that occurs, a new opportunity opens up to learn more about our natural world.
