NASA | Uncovering Winter's Mystery

The video discusses the variability of snow over recent years, highlighting that while some years have seen significant snowfall, others have not. It explains the importance of snow in the water cycle, acting as a reservoir that releases water during warmer months. Factors like El Nino and the North Atlantic Oscillation significantly impact snowfall. The video also emphasizes the importance of studying snow from space for uniform global measurements and improved climate models. NASA's ongoing research, including field campaigns and satellite launches, aims to enhance understanding and forecasting of winter storms and precipitation patterns.

What role does snow play in the water cycle?

• It acts as a permanent water source.

• It reflects sunlight, reducing heat absorption.

• It stores water and releases it during warmer months.

• It prevents soil erosion.

What was a significant factor for the increased snow in 2010?

• A La Nina year

• A high-pressure system over the equator

• A positive North Atlantic Oscillation

• An El Nino year

How does the North Atlantic Oscillation affect snow patterns?

• It increases ocean temperatures.

• It influences the movement of cold air from the Arctic.

• It causes more rainfall in the Pacific region.

• It reduces the amount of moisture in the atmosphere.

Why is it important to study snow from space?

• To measure snow depth in backyards.

• To obtain uniform global measurements.

• To predict snowfall in specific cities.

• To track snowstorms in real-time.

What is the purpose of NASA's field campaign mentioned in the transcript?

• To study snow patterns in Antarctica.

• To develop new snow measurement tools.

• To understand winter storm mechanics.

• To launch a new weather satellite.
