Fog is a visible aerosol consisting of tiny water droplets or ice crystals suspended in the air at or near the Earth's surface. [1] [2] Fog can be considered a type of low-lying cloud usually resembling stratus and is heavily influenced by nearby bodies of water, topography, and wind conditions. In turn, fog affects many human activities, such ...

2025年1月7日 · Fog, cloud of small water droplets that is near ground level and sufficiently dense to reduce horizontal visibility to less than 1,000 metres (3,281 feet). The word fog also may refer to clouds of smoke particles, ice particles, or mixtures of these components.

Evaporation or Mixing Fog. This type of fog forms when sufficient water vapor is added to the air by evaporation and the moist air mixes with cooler, relatively drier air. The two common types are steam fog and frontal fog. Steam fog forms when cold air moves over warm water.

The meaning of FOG is vapor condensed to fine particles of water suspended in the lower atmosphere that differs from cloud only in being near the ground. How to use fog in a sentence.

2013年10月14日 · The most common form of fog, known as radiation fog, typically occurs on clear nights as the earth's surface cools moist air immediately above it.

2024年10月19日 · Fog plays a crucial role in many ecosystems, particularly in regions with limited rainfall. Fog acts as a water source for plants, animals, and even human communities. Fog as a Water Source: In coastal deserts like the Namib or Atacama, plants and animals

2024年12月9日 · Fog is a meteorological phenomenon characterized by suspended water droplets or ice crystals near the Earth’s surface. Fog forms through condensation processes in air, resulting in reduced visibility. Fog types vary based on formation mechanisms and conditions. Fog impacts air quality, transportation safety, and climate patterns.

Fog is a visible aerosol comprising tiny water droplets or ice crystals suspended in the air at or near the Earth’s surface. Nearby bodies of water, topography, and weather conditions are three factors that influence fog. You can think of it as a low-lying cloud. Fog most resembles stratus clouds, or low-lying, horizontally layered clouds.

2023年11月2日 · Fog forms when the air temperature and dew point approach the same value, either through cooling of the air (producing advection, radiation, or upslope fog) or by adding enough moisture to raise the dew point (producing steam or frontal fog). When composed of ice crystals, it is called ice fog.

2023年12月5日 · Fog is a meteorological phenomenon that has captured human curiosity for centuries. It occurs when tiny water droplets or ice crystals suspend in the air near the Earth's surface, reducing visibility and creating an eerie and mysterious atmosphere.
