Right panel: details are similar to the left panel, but using the Rossby … It has been proposed that a number of regional weather extremes in the Northern Hemisphere associated with blocked atmospheric circulation patterns may have been caused by quasiresonant amplification of Rossby waves. Examples include the 2013 European floods, the 2012 China floods, the 2010 Russian heat wave, the 2010 Pakistan floods and the 2003 European heat wave. Even taking global warming into account, the 2003 heat wave would have been highly …

Rossby Number, Planetary Vorticity, and Traditional Approximation

The Rossby number (Ro), named for Carl-Gustav Arvid Rossby, is a dimensionless number used in describing fluid flow. The Rossby number is the ratio of inertial force to Coriolis force, terms $${\displaystyle \mathbf {v} \cdot \nabla \mathbf {v} \sim U^{2}/L}$$ and Visa mer • Coriolis force – Force on objects moving within a reference frame that rotates with respect to an inertial frame • Centrifugal force – Type of inertial force Visa mer 1. ^ M.
