Clouds have an enormous influence on the greenhouse effect. This is why it is important to find out what role clouds play in the climate and how they influence the thermal balance of the earth. Meteorologists studying clouds in Europe tell us that by learning about the microphysical processes that occur naturally in clouds, researchers gain new fundamental knowledge that can help improve weather and climate forecast models. This program explores known, speculated and unknown information about cloud structures and mechanisms. The newest technology and how it works is also presented. Students will discover how scientists study cloud formation by generating artificial clouds in a laboratory. They will research how clouds originate and how they react to surrounding natural elements. They will also see how microwave radiometers, lasers and satellites are used in researching cloud development.
