Snow Donut
A snow donut, also known as a "snow roller" or "snow bale," is a natural and relatively rare occurrence in which a cylindrical or donut-shaped snowball forms and rolls across a snowy landscape. Snow donuts are formed when a combination of factors comes into play: a layer of loose, dry snow covers a slightly denser and icy layer beneath it, and then wind or other external forces initiate the rolling motion.
As the wind pushes the loose snow, it gathers and rolls into a rounded shape, creating the appearance of a donut or snowball with a hole in the center. The cylindrical shape is maintained as the snow roller moves across the ground, collecting more snow along the way. Snow donuts are captivating and unusual sights, and they can vary in size from a few inches to several feet in diameter, depending on the specific conditions that led to their formation.
Supercell
A supercell is an exceptionally powerful and organized thunderstorm known for its rotating updraft, which can lead to severe weather events like large hail, intense tornadoes, and damaging winds. These long-lasting storms feature a rotating mesocyclone within, which enables sustained vertical growth and rotation. While not all supercells produce tornadoes, they are the most prone to doing so. Supercells can also generate massive hailstones and powerful wind downbursts. These storms are closely monitored by meteorologists due to their potential for significant damage, emphasizing the importance of timely severe weather warnings and public safety measures.
Virga
Virga describes the occurrence when precipitation falls from clouds but vanishes before hitting the ground. It often looks like wispy streaks extending from the base of a cloud but doesn't reach the Earth's surface. Virga happens when raindrops or snowflakes encounter drier or warmer air below the cloud, causing them to evaporate before landing. This is a common sight in dry regions and is often seen as visible precipitation trails suspended beneath clouds, especially in high-based thunderstorms or arid desert climates.
Water Spout
A waterspout is a captivating event that occurs over bodies of water. It's characterized by a rotating column of air extending from a cloud and making contact with the water's surface. Waterspouts come in two types: tornado waterspouts and fair-weather waterspouts. Tornado waterspouts form during severe thunderstorms and can be destructive. In contrast, fair-weather waterspouts develop in calmer conditions and are less powerful. They are typically formed by the convergence of warm, moist air over the water and cooler air aloft. Waterspouts exhibit rotation and often display a visible funnel extending from the cloud to the water's surface, creating a captivating spectacle over open water.
Frost Beard
A frost beard, sometimes referred to as an "ice beard", is a whimsical and picturesque natural phenomenon that occurs during extremely cold weather conditions. It forms when moisture in the air freezes on the facial hair of individuals, such as a beard or mustache, as they breathe or exhale in frigid temperatures.

Ice frost adorns objects with a sparkling, white, and often intricate design, enhancing the winter scenery with its beauty. It exemplifies the exquisite details found in nature, turning ordinary landscapes into enchanting, frost-covered wonderlands.
WIlliwaw
A williwaw is a sudden and violent gust of cold wind that descends from high mountain slopes or glaciers and rushes down to the sea in coastal regions. These unpredictable and powerful windstorms are common in places like Alaska and the Aleutian Islands, as well as other mountainous, polar or subpolar regions around the world.
Williwaws can have significant impacts on maritime activities, especially for ships and boats in coastal waters. These gusty winds can create hazardous conditions, including rough seas and turbulent waters, making navigation challenging and increasing the risk of accidents. The term "williwaw" is derived from the Unangan language, spoken by the indigenous people of the Aleutian Islands, and it has become synonymous with these sudden and ferocious coastal winds.
Gustnado
A Gustnado is a relatively weak and short-lived tornado-like phenomenon that forms along the gust front of a severe thunderstorm. It's not a true tornado, as it doesn't develop from the same atmospheric conditions, but it shares some visual similarities. Gustnadoes are typically small and appear as spinning dust or debris clouds near the ground, often in the vicinity of a thunderstorm's outflow boundary.
These whirlwinds are generated by strong downdrafts or outflow winds from a thunderstorm colliding with the ground and causing horizontal vorticity, resulting in a rotating column of air. While Gustnadoes are generally less intense than actual tornadoes, they can still cause localized damage and are important to monitor for severe weather warnings.
Ball Lightning
Ball lightning is a rare weather phenomenon characterized by the appearance of luminous, glowing spheres of light that seem to hover, float, or dart around in the atmosphere. These mysterious orbs typically last for only a few seconds to a minute before vanishing or exploding with a loud bang. Despite extensive research, the exact cause of ball lightning remains uncertain. It's been reported to occur during thunderstorms and can vary in size from golf ball-sized to several feet in diameter. Witnesses have described them as colorful and mesmerizing, yet they remain one of the least understood and scientifically unexplained atmospheric phenomena, adding an intriguing element to the world of weather wonders.
