RISAssociations between the Global Energy Cycle and Regional Rainfall in South Africa and Southwest Australia
Publisher: American Meteorological Society
Abstract: Large-scale atmospheric processes in the Southern Hemisphere are examined on both seasonal and daily time scales in order to seek associations between these and regional rainfall variability in the summer rainfall areas ...
Does the South American Monsoon Influence African Rainfall?
Publisher: American Meteorological Society
Abstract: Teleconnections between the South American monsoon and southern African rainfall are investigated for years with Benguela Niño or Niña events in the South Atlantic. During these events, it is found that substantial rainfall ...
Multidecadal Variability in the Climate System over the Indian Ocean Region during the Austral Summer
Publisher: American Meteorological Society
Abstract: Several independent historical studies of global atmospheric and oceanic parameters have identified low-frequency fluctuations in the global climate system. Much of this research has focused on Europe, the Atlantic Ocean, ...
Numerical Modeling of a Coastal Trapped Disturbance. Part II: Structure and Dynamics
Publisher: American Meteorological Society
Abstract: A detailed analysis of a simulation of a coastal trapped disturbance (CTD) using the Colorado State University Regional Atmospheric Modeling System (RAMS) is presented. The CTD considered (15?18 May 1985) represents an ...
Numerical Modeling of a Coastal Trapped Disturbance. Part I: Comparison with Observations
Publisher: American Meteorological Society
Abstract: The coastal trapped disturbance (CTD) of 15?17 May 1985 represents an example of a strong mesoscale trapped event along the west coast of North America with abrupt transitions in many basic meteorological parameters. In ...
Building a Tropical–Extratropical Cloud Band Metbot
Publisher: American Meteorological Society
Abstract: n automated cloud band identification procedure is developed that captures the meteorology of such events over southern Africa. This ?metbot? is built upon a connected component labeling method that enables blob detection ...
On the Likelihood of Tropical–Extratropical Cloud Bands in the South Indian Convergence Zone during ENSO Events
Publisher: American Meteorological Society
Abstract: AbstractThe Southern Hemisphere subtropical convergence zones are important regions of rainfall in the subtropics. The south Indian Ocean convergence zone (SICZ) has the strongest seasonality and exhibits substantial ...
Contributions of Indian Ocean Sea Surface Temperatures to Enhanced East African Rainfall
Publisher: American Meteorological Society
Abstract: Links between extreme wet conditions over East Africa and Indian Ocean sea surface temperatures (SST) are investigated during the core of the so-called short rain season in October?November. During periods of enhanced East ...
Agulhas Leakage Predominantly Responds to the Southern Hemisphere Westerlies
Publisher: American Meteorological Society
Abstract: he Agulhas Current plays a crucial role in the thermohaline circulation through its leakage into the South Atlantic Ocean. Under both past and present climates, the trade winds and westerlies could have the ability to ...
Decoupling of the Agulhas Leakage from the Agulhas Current
Publisher: American Meteorological Society
Abstract: he relationship between the Agulhas Current and the Agulhas leakage is not well understood. Here, this is investigated using two basin-scale and two global ocean models of incrementally increasing resolution. The response ...
