Energy Accumulation and Emanation at Low Latitudes. Part III: Forward and Backward Accumulation

摘要: Abstract Short equatorially trapped Rossby waves are usually thought to he and dissipated nea the region of creation because their relatively slow group speeds low amplitude basic state within which they reside. Only long waves, with stronger speeds, assumed move far away from forcing area producing remote effects or teleconnections. These restrictions on regions influence only valid in a motionless that is constant longitude. If changes zonal direction, even short have considerable effects. Using ray-tracing techniques nonlinear numerical models, impact zonally varying characteristics equatorial modes investigated. The original low-latitude energy accumulation zone theory Webster Chang extended include complete family tropical waves. In regions, majority ...
