The wavefront shape, position, and evolution of a great solitary wave of translation

Doppler radar mapped the evolution of a pair of atmospheric solitary waves emanating from a thunderstorm complex. The 100-km-long curved wavefront and position of these few-kilometer-wide waves are hypothesized to be a result of an amplitude-dependent wave speed. The observed unfolding is compared with a solution of the nonlinear integro-differential equation governing the evolution of finite amplitude disturbances in stratified media.<
