Mechanisms of Climate Change in the Semiarid African Sahel: The Local View
Publisher: American Meteorological Society
Abstract: Application of the moist static energy framework to analyses of vertical stability and net energy in the Sahel sheds light on the divergence of projections of climate change. Two distinct mechanisms are sketched. In one, ...
Potentially Predictable Components of African Summer Rainfall in an SST-Forced GCM Simulation
Publisher: American Meteorological Society
Abstract: An ensemble of general circulation model (GCM) integrations forced by observed sea surface temperature (SST) represents the climate response to SST forcing as well as internal variability or ?noise.? Signal-to-noise analysis ...
Interannual Variability of Caribbean Rainfall, ENSO, and the Atlantic Ocean
Publisher: American Meteorological Society
Abstract: The large-scale ocean?atmosphere patterns that influence the interannual variability of Caribbean?Central American rainfall are examined. The atmospheric circulation over this region is shaped by the competition between ...
Interdecadal Changes in the ENSO Teleconnection to the Caribbean Region and the North Atlantic Oscillation
Publisher: American Meteorological Society
Abstract: The El Niño?Southern Oscillation (ENSO) phenomenon and variability in the subtropical North Atlantic high sea level pressure (SLP) are known to affect rainfall in the Caribbean region. An El Niño event is associated with ...
Resolving Contrasting Regional Rainfall Responses to El Niño over Tropical Africa
Publisher: American Meteorological Society
Abstract: he evolution of El Niño can be separated into two phases?namely, growth and mature?depending on whether the regional sea surface temperature has adjusted to the tropospheric warming in the remote tropics (tropical regions ...
Revisiting the ENSO Teleconnection to the Tropical North Atlantic
Publisher: American Meteorological Society
Abstract: AbstractOne of the most robust remote impacts of El Niño?Southern Oscillation (ENSO) is the teleconnection to tropical North Atlantic (TNA) sea surface temperature (SST) in boreal spring. However, important questions still ...
CMIP5 Projected Changes in the Annual Cycle of Precipitation in Monsoon Regions
Publisher: American Meteorological Society
Abstract: nalyses of phase 5 of the Coupled Model Intercomparison Project (CMIP5) experiments show that the global monsoon is expected to increase in area, precipitation, and intensity as the climate system responds to anthropogenic ...
The ENSO Teleconnection to the Tropical Atlantic Ocean: Contributions of the Remote and Local SSTs to Rainfall Variability in the Tropical Americas
Publisher: American Meteorological Society
Abstract: Recent developments in Tropical Atlantic Variability (TAV) identify the El Niño?Southern Oscillation (ENSO) as one of the leading factors in the interannual climate variability of the basin. An ENSO event results in ...
