Question

Rossby waves are associated with?

• A. Cyclones
• B. Earthquakes
• C. Jetstreams
• D. volcanoes

Answer 1

Answer: (C)

Jetstreams

Rossby waves, also known as planetary waves, are a natural phenomenon in the atmosphere and oceans of planets that largely owe their properties to rotation. Rossby waves are a subset of inertial waves. Atmospheric Rossby waves on Earth are giant meanders in high-altitude winds with major influence on weather. These Rossby waves are associated with pressure systems and the jet stream.
Oceanic Rossby waves move along the thermocline: that is, the boundary between the warm upper layer of the ocean and the cold deeper part of the ocean.
Rossby waves in the Earth's atmosphere are easy to observe as (usually 4-6) large-scale meanders of the jet stream. When these deviations become very pronounced, they detach the masses of cold, or warm, air that become cyclones and anticyclones and are responsible for day-to-day weather patterns at mid-latitudes. Rossby waves may be partly responsible for the fact that eastern continental edges.
