Meteorology Quiz 2 B

What distinguishes stratocumulus clouds from nimbostratus clouds?

• Stratocumulus clouds are low-altitude clouds with a layered appearance, while nimbostratus clouds are thick, gray clouds associated with precipitation.

• Stratocumulus clouds have a wispy, high-altitude appearance, while nimbostratus clouds are low, dense clouds often producing rain

• Stratocumulus clouds are towering clouds with an anvil-shaped top, while nimbostratus clouds have a uniform gray layer covering the sky.

• Stratocumulus clouds are thin, wispy clouds formed from ice crystals, while nimbostratus clouds indicate fair weather.

Which cloud type is often described as a "blanket" covering the sky, appearing gray and uniform, and associated with steady rain or snow?

• Altostratus

• Stratocumulus

• Cirrus

• Cumulus

How is cloud coverage typically assessed through visual observation?

• By estimating the percentage of the sky covered by clouds

• By counting the number of different cloud types present

• By measuring the altitude of the clouds

• By analyzing the color of the clouds

Which of the following terms is used to describe a sky with complete cloud coverage?

• Clear sky

• Overcast sky

• Partly cloudy sky

• Scattered clouds

When observing the sky for cloud coverage, what does a "partly cloudy" condition indicate?

• Approximately 100% cloud coverage

• Clouds covering less than 25% of the sky

• Clouds covering around 50% to 75% of the sky

• Clouds covering around 25% to 50% of the sky

What is the significance of estimating cloud coverage for aviation and maritime navigation?

• It helps pilots determine the best altitude for flight paths

• It assists in identifying potential weather hazards and planning routes accordingly

• It determines the likelihood of encountering turbulence

• It has no impact on navigation safety

How does visual observation of cloud coverage contribute to weather forecasting?

• By providing data on cloud composition

• By determining the direction of cloud movement

• By indicating atmospheric pressure changes

• ) By helping meteorologists understand current weather conditions and predict future developments

Which of the following factors primarily affects visibility by obstructing the passage of light through the atmosphere?

• Air temperature

• Humidity levels

• Atmospheric particles and pollutants

• Wind speed

How does fog affect visibility?

• It enhances visibility by diffusing light rays.

• It reduces visibility by scattering and absorbing light.

• It has no effect on visibility.

• It increases visibility by clearing the atmosphere of pollutants.

What impact does precipitation have on visibility?

• It generally improves visibility by washing away atmospheric particles.

• It reduces visibility due to the presence of water droplets or ice crystals in the air.

• It has no significant effect on visibility.

• It enhances visibility by dispersing light more evenly.
