RISVariability and Evolution of African Easterly Wave Structures and Their Relationship with Tropical Cyclogenesis over the Eastern Atlantic
Publisher: American Meteorological Society
Abstract: frican easterly waves (AEWs) are objectively tracked between West Africa and the tropical Atlantic based on the CFSRv2 data for 1979 to 2012. The characteristics of the troughs of the AEWs at the West African coast are ...
African Easterly Wave Dynamics in a Mesoscale Numerical Model: The Upscale Role of Convection
Publisher: American Meteorological Society
Abstract: o examine the dynamical role of convection in African easterly wave (AEW) life cycles the Weather Research and Forecasting (WRF) model is used to simulate the evolution of a single AEW from September 2004. The model ...
Convection over Tropical Africa and the East Atlantic during the West African Monsoon: Regional and Diurnal Variability
Publisher: American Meteorological Society
Abstract: he geographic and diurnal variability of moist convection over tropical Africa and the east Atlantic is examined using the Tropical Rainfall Measuring Mission (TRMM) satellite and related to the variability of the convective ...
The Influence of African Easterly Waves on Convection over Tropical Africa and the East Atlantic
Publisher: American Meteorological Society
Abstract: sing data from the Tropical Rainfall Measuring Mission (TRMM), the modulation of convection by African easterly waves (AEWs) is investigated over regions of the east Atlantic and tropical Africa. To explain the modulation ...
The Role of Convectively Coupled Atmospheric Kelvin Waves on African Easterly Wave Activity
Publisher: American Meteorological Society
Abstract: he role of convectively coupled atmospheric Kelvin waves (CCKWs) on African easterly wave (AEW) activity is explored over tropical Africa during boreal summer. Examination of the pre-Alberto AEW in 2000 highlights the ...
Changes in Seasonal Large-Scale Extreme Precipitation in the Mid-Atlantic and Northeast United States, 1979–2019
Publisher: American Meteorological Society
The Interannual Stability of Cumulative Frequency Distributions for Convective System Size and Intensity
Publisher: American Meteorological Society
Abstract: The characteristics of convective system populations in West Africa and the western Pacific tropical cyclone basin were analyzed to investigate whether interannual variability in convective activity in tropical continental ...
Three-Dimensional Structure and Dynamics of African Easterly Waves. Part III: Genesis
Publisher: American Meteorological Society
Abstract: This paper promotes the view that African easterly waves (AEWs) are triggered by localized forcing, most likely associated with latent heating upstream of the region of observed AEW growth. A primitive equation model is ...
Three-Dimensional Structure and Dynamics of African Easterly Waves. Part I: Observations
Publisher: American Meteorological Society
Abstract: The mean structure of African easterly waves (AEWs) over West Africa and the adjacent Atlantic is isolated by projecting dynamical fields from reanalysis and radiosonde data onto space?time-filtered satellite-derived ...
Three-Dimensional Structure and Dynamics of African Easterly Waves. Part II: Dynamical Modes
Publisher: American Meteorological Society
Abstract: A primitive equation model is used to study the linear normal modes of the African easterly jet (AEJ). Reanalysis data from the summertime mean (June?September; JJAS) flow is used to provide zonally uniform and wavy basic ...
