How High In the Sky Are Clouds? - ThoughtCo
2018年3月18日 · High clouds have base heights of 3,000 to 7,600 meters (10,000 to 25,000 ft) in polar regions, 5,000 to 12,200 meters (16,500 to 40,000 ft) in temperate regions, and 6,100 to 18,300 meters (20,000 to 60,000 ft) in the tropical region.
List of cloud types - Wikipedia
High clouds form in the highest and coldest region of the troposphere from about 5 to 12 km (16,500 to 40,000 ft) in temperate latitudes. [9] [10] At this altitude water almost always freezes so high clouds are generally composed of ice crystals or supercooled water droplets.

2023年4月12日 · Low-level clouds occur at ground level up to 6,500 ft (1,981 m), middle clouds occur between 6,500-20,000 ft (1,981 – 6,096.0 m), and high clouds begin at 20,000 ft (6,096.0 m) above the Earth’s surface.
Cloud Chart - National Weather Service
Low level clouds are generally based at or below 6,500 feet above ground, mid-level clouds are generally based between 6,500 feet and 15,000 feet above ground, and high level clouds are generally based more than 15,000 feet above ground.
Cloud Classification - National Weather Service
High-level clouds occur above about 20,000 feet and are given the prefix "cirro-". Due to cold tropospheric temperatures at these levels, the clouds primarily are composed of ice crystals, and often appear thin, streaky, and white (although a low sun angle, e.g., near sunset, can create an array of color on the clouds).

2024年12月5日 · But all clouds look a little bit different from one another, and sometimes these differences can help us predict a change in the weather. Here’s a list of some of the most common cloud types you might spot in the sky: High Clouds (16,500-45,000 feet)
Cloud Types - Center for Science Education
How Are Clouds Classified? Most clouds can be divided into groups (high/middle/low) based on the height of the cloud's base above the Earth's surface. Other clouds are grouped not by their height, but by their unique characteristics, such as those that form over mountains (lenticular clouds) or beneath existing clouds (mammatus clouds).
