Fog英文什麼意思

在英文中,"fog" 是指一種大氣現象,指的是接近地面的低空中的濃厚水汽凝結成細小水滴而形成的一種天氣現象。這種天氣現象會導致能見度降低,使得物體看起來模糊不清。

Fog can be classified into different types based on its characteristics and the weather conditions that cause it. Here are some common types of fog:

  1. Radiation fog: This type of fog forms on clear nights when heat radiates from the Earth's surface into the air, causing the air to cool and become saturated, leading to the formation of fog near the ground.

  2. Advection fog: This occurs when warm, moist air moves over a cool surface, such as cold ground or water, and the air cools sufficiently to form fog.

  3. Upslope fog: As the name suggests, this type of fog forms when air is forced to rise over a mountain or hill, causing it to cool and potentially form fog.

  4. Steam fog (or evaporation fog): This is a type of fog that forms when very cold air moves over a warmer body of water, and the moist air near the surface of the water cools and condenses as it is advected inland.

  5. Ice fog: This is a type of fog that forms in very cold temperatures when water vapor condenses directly into solid ice particles in the air.

Fog can have various impacts on daily life, particularly affecting transportation and outdoor activities. It is a common occurrence in many parts of the world, especially in coastal regions, valleys, and areas near large bodies of water.
