Q:

What type of cloud produces heavy rain, lightning, thunder, hail and strong winds?

A:

Quick Answer

Cumulonimbus clouds produce rain, hail and other attributes of thunderstorms. These clouds begin as cumulus clouds that achieve vertical growth. Tornadoes are also a product of cumulonimbus clouds.

Full Answer

Cumulonimbus clouds have a layered effect, which is indicative of the cloud growth. The reach of the cloud extends from 1000 feet above the surface to more than 40,000 feet. Water vapor and updrafts within a cumulus cloud create the larger cumulonimbus as part of the thunderstorm cycle. Sometimes the anvil-shaped top of the cloud is visible before the lower part of the clouds, which appears as a wall. These clouds also produce winter storms, such as blizzards.

    How do meteorologists measure cloud cover?

    A:

    Meteorologists measure cloud cover in oktas, units of measure that divide the sky into eighths. Readings run from 0 oktas, a clear sky, up to 8 oktas, a completely overcast sky. Special all-sky cameras, which photograph the sky images onto polished metal spheres, take the measurements.

    What kind of cloud is fog?

    A:

    Fog is a type of stratus cloud. Unlike other clouds, fog forms at ground level when the air on the ground cools, and water vapor condenses into suspended water droplets. This typically occurs in humid weather.

  • Q:

    What measures cloud cover?

    A:

    Weather satellites are used in measuring daily cloud cover. Technological advancements have made it possible to launch satellites in space to observe and collect cloud data from beyond the Earth's atmosphere. A low-tech alternative is to use a spherical mirror, or "sky mirror," to gauge cloud coverage.
