What are rossy waves? Discuss the role played by them in shaping the climate of the earth.

Rossy waves refer to Polar jet streams that encircle both poles and blue at an altitude of 8 to 13 km above Earth.

Features:

• Stronger in summer.
• Anticlockwise circulation.
• Aided and guided by Coriolis force.

Role in climate of earth:

• Restrict cold winds to polar areas.
• Bring precipitation as snowfall.
• Weak rossy waves spill icy winds in Europe and North America.
• Influence planetary wind patterns.
• Regulate temperature in polar areas.

The Rossy waves are critical to our understanding of the atmosphere and global climate.
