Mysterious Weather Clouds: Why do some clouds produce rain and some do not

The video discusses the ACTOSS system, which measures cloud turbulence using advanced instruments. It explores how turbulence affects cloud properties and rain formation. Scientists use cloud chambers to simulate and study droplet behavior, including snow and hail formation. The research also examines how cloud composition influences solar radiation and climate, highlighting the cooling effect of low clouds and the warming effect of high clouds.

What is the primary function of the ACTOSS system?

• To record sonic impulses and measure cloud properties

• To measure wind speed in open fields

• To predict weather patterns

• To simulate cloud formation in laboratories

How do scientists at the Institute for Atmospheric Physics study cloud droplet behavior?

• By using a cloud chamber with controlled wind conditions

• By observing natural clouds in the sky

• By using satellite imagery

• By creating artificial rain in a laboratory

What role do strong winds play in the cloud simulation chamber?

• They increase the humidity inside the chamber

• They help in forming larger droplets

• They keep the droplets suspended and moving

• They reduce the temperature of the chamber

What conditions are studied in the cloud chamber to understand snow formation?

• High humidity and low pressure

• Temperatures as low as minus 30 degrees Celsius

• High temperatures and strong sunlight

• Low wind speeds and high altitude

How do low clouds typically affect Earth's climate?

• They increase atmospheric pressure

• They contribute to global warming

• They cool the Earth

• They have no significant effect
