Mist is a phenomenon caused by small droplets of water suspended in the cold air, usually by condensation. Physically, it is an example of a dispersion. It is most commonly seen where water vapor in warm, moist air meets sudden cooling, such as in exhaled air in the winter, or when throwing water onto the hot stove of a sauna.

In our meteorological glossary fog is defined as 'obscurity in the surface layers of the atmosphere, which is caused by a suspension of water droplets'. By international agreement (particularly for aviation purposes) fog is the name given to resulting visibility less than 1 km. However, in forecasts for the public, this generally refers to visibili...
Mist is defined as 'when there is such obscurity and the associated visibility is equal to or exceeds 1000 m.' Like fog, mist is still the result of the suspension of water droplets, but simply at a lower density. Mist typically is quicker to dissipate and can rapidly disappear with even slight winds, it's also what you see when you can see your br...
A third term you might also hear mentioned is haze. This is a slightly different phenomenon which is a suspension of extremely small, dry particles in the air, not water droplets. These particles are invisible to the naked eye, but sufficient to give the air an opalescent appearance. These particles can also contribute to creating a red skyat sunri...
Aug 21, 2024 · Mist is a much more sudden event and can rapidly appear when warm moist air comes in contact with a cold surface. The warm moist air you exhale on a cold day, and the air coming into contact with volcanic ash are just two examples of rapid-appearing mist.
- Sunny. It is a condition where the sky is clear, and no clouds are blocking the sunlight. The temperature during such weather is warm. Sunny weather is typical in the spring and summer seasons but is also found in autumn and winter.
- Cloudy. Such conditions happen when clouds obstruct the sunlight on its way to the Earth’s surface. Cloudy days can be cold or warm, depending on the humidity, which may or may not accompany the rain.
- Windy. Wind can be defined as air in motion. It happens when there is a pressure imbalance between two regions. Air moves from a high-pressure region to a low-pressure region.
- Rainy. This type of weather happens when the sky is covered with clouds. Thus, cloudy weather (either partial or overcast) can become rainy weather when the clouds are large, causing much precipitation.
- Polar vortex. The menacing phrase "polar vortex" is a relatively new term for winter weather forecasting, but meteorologists have understood it as a concept for decades.
- Atmospheric (barometric) pressure. Humans inhabit the very bottom of the Earth's atmosphere and everything above creates atmospheric pressure. High-pressure systems form when downward pressure creates a clockwise air rotation, unlike low-pressure systems, which generate counter-clockwise rotation.
- Inch of mercury. Inch of mercury is a unit used to measure air pressure. It represents the amount of pressure the atmosphere places on a one-inch column of mercury under standard gravity at zero degrees Celsius.
- Ball lightning. Lightning in its traditional form is frightening and deadly on its own, but ball lightning is scary even in the context of instant electrocution from the heavens.
Sep 20, 2023 · Weather around the world falls into three basic categories: precipitation, obscurations, and "other" phenomena. Synoptic Meteorology. Time. Wind. Air Masses. Surface Weather Maps. Norwegian Cyclone Model. Heat Index. Wind Chill.
Jan 12, 2021 · The six common types of weather create all weather conditions. With the right humidity, wind, atmospheric pressure, temperature, clouds, and precipitation, a rainstorm happens. However, the most impactful weather conditions are severe weather.
