Abstract We analyze the stratospheric waves in models participating phase 1 of Stratosphere–troposphere Processes And their Role Climate (SPARC) Quasi‐Biennial Oscillation initiative (QBOi). All have robust Kelvin and mixed Rossby‐gravity wave modes winds temperatures at 50 hPa represent them better than most Coupled Model Intercomparison Project Phase 5 (CMIP5) models. There is still some spread among models, especially concerning waves. attribute variability equatorial QBOi part to varying...
Abstract Mesoscale convective systems (MCSs) produce over 50% of tropical precipitation and account for the majority extreme rainfall flooding events. MCSs are considered building blocks larger‐scale convectively coupled equatorial waves (CCEWs). While CCEWs can provide favorable environments convection, how systematically impact organized convection thereby MCS characteristics is less clear. We examine this question by analyzing a global tracking data set. During active phase CCEWs,...
Abstract The dominant structural variability of African easterly waves (AEWs) is explored using an empirical orthogonal function (EOF) approach. structure AEWs obtained by projecting the wind fields from reanalysis data and satellite-derived brightness temperature T b onto principal components associated with EOF patterns filtered ( EOF) 700-hPa meridional (v700 EOF). wave depicted has confined convection circulation mostly south jet. It shares many characteristics analyzed discussed in...
Abstract Observational evidence of two extratropical pathways to forcing tropical convective disturbances is documented through a statistical analysis satellite-derived OLR and ERA5 reanalysis. The mechanism the resulting are found strongly depend on structure background zonal wind. Although Rossby wave propagation prohibited in easterlies, modeling studies have shown that can still excite equatorial waves resonance between tropics extratropics. Here this “remote” pathway investigated for...
