A density analysis of a developing deep trough in the westerlies.
… of a rapidly deepening trough in the westerly zonal circulation over the United States. Material was gathered during a continuous five day period at intervals of 24 hours in a dense radiosonde network. The analysis was conducted in 2 kilometer layers from the surface to 20 kilometers with …

Role of Planetary Wave-Tide-Gravity Wave Interactions In Whole Atmosphere Coupling
… observation. The residual mean meridional and zonal circulation, parameterized GW forcing, and resolved planetary and tidal forcing represent intra-seasonal changes during NH major SSWs, which result in the different behaviors of IHCs. Warmings around the summer polar mesopause are more …

Modulation of South African summer rainfall by global climatic processes
… velocity potential and derived parameters (the Zonal Circulation and Meridional Circulation Indices). The results suggest that the vertical tropospheric cells are among the important associated components which modulate climate across southern Africa, and that broad scale flows have an impact …

Marine weather variability, tropical cyclone prediction and impacts in the Southwest Indian Ocean
… model-assimilated data. The evolution of monsoon circulations associated with composite tropical cyclones distinguished by trade is studied. Case study tropical cyclones are investigated and impacts evaluated through comparison of Yea!' and 'model' datasets. The seasonal variability of intense TC …

Mechanisms and prediction of climate variability in tropical North Africa
… Atlantic. The monsoon systems control the mean circulation of this region. Superimposed on this basic state, large-scale variability dictates the life of the people and their socio-economic activities. The tropical North Africa climate exhibits a spectra! energy mainly in the ENSO and decadal …
