METEOROLOGY – EA URFACE & OCEAN-ATMOPHERE CALCULATOR
Rossby Wave Speed
A precise tool.
What is the Rossby Wave Speed & How does it work?
Rossby waves are large-scale atmospheric and oceanic waves that play a crucial role in the global circulation patterns. These waves are named after Carl-Gustaf Rossby, who first described them in the 1930s.
The speed of Rossby waves is influenced by the Coriolis effect, which depends on latitude. The wave speed decreases as you move towards the equator due to the weakening Coriolis force.
v_R = frac{U}{f}
v_R = Rossby wave speed, U = zonal wind speed, f = Coriolis parameter

Frequently Asked Questions
What are Rossby waves?
Rossby waves are large-scale atmospheric and oceanic waves that influence global circulation patterns.
Who first described Rossby waves?
Rossby waves were first described by Carl-Gustaf Rossby in the 1930s.
How does the speed of Rossby waves change with latitude?
The speed of Rossby waves decreases as you move towards the equator due to the weakening Coriolis force.
What factors influence the speed of Rossby waves?
The speed of Rossby waves is influenced by the zonal wind speed and the Coriolis parameter.
How do you calculate the Rossby wave speed?
Rossby wave speed (v_R) is calculated using the formula v_R = U / f, where U is the zonal wind speed and f is the Coriolis parameter.
What is the significance of Rossby waves in meteorology?
Rossby waves play a crucial role in global circulation patterns, affecting weather systems and climate.
Can you explain the Coriolis effect’s impact on Rossby waves?
The Coriolis effect causes Rossby waves to deflect to one side as they move, with this deflection being stronger at higher latitudes.
