RISObservational Assessment of Nonlocal Heat Flux Feedback in the North Atlantic by GEFA
Publisher: American Meteorological Society
Abstract: ost previous studies have proven the local negative heat flux feedback (the surface heat flux response to SST anomalies) in the midlatitude areas. However, it is uncertain whether a nonlocal heat flux feedback can be ...
Linking Observations of the Asian Monsoon to the Indian Ocean SST: Possible Roles of Indian Ocean Basin Mode and Dipole Mode
Publisher: American Meteorological Society
Abstract: The authors investigate the relationship between sea surface temperature (SST) in the tropical Indian Ocean (TIO) and the seasonal atmosphere circulation in the Asian monsoon region (AMR) using the maximum covariance ...
Salient Differences in Tropical Cyclone Activity over the Western North Pacific between 1998 and 2016
Publisher: American Meteorological Society
Abstract: AbstractPrevious studies have suggested that tropical cyclone (TC) seasons over the western North Pacific (WNP) in the decaying years of El Niño events are generally less active than normal. The two strongest El Niño events ...
Regional Dynamics of Seasonal Variability in the South China Sea
Publisher: American Meteorological Society
Abstract: Dynamics of the seasonal cycle of sea surface height (SSH) in the South China Sea (SCS) are studied using observations as well as numerical and theoretical models. Seasonal variability of the SCS is interpreted in light ...
Observed Atmospheric Responses to Global SST Variability Modes: A Unified Assessment Using GEFA
Publisher: American Meteorological Society
Abstract: The authors present a comprehensive assessment of the observed atmospheric response to SST variability modes in a unified approach using the Generalized Equilibrium Feedback Analysis (GEFA). This study confirms a dominant ...
Assessing Atmospheric Response to Surface Forcing in the Observations. Part II: Cross Validation of Seasonal Response Using GEFA and LIM
Publisher: American Meteorological Society
Abstract: he authors compared the assessment of the seasonal cycle of the atmospheric response to surface forcing in three statistical methods, generalized equilibrium feedback analysis (GEFA), linear inverse modeling (LIM), and ...
Evidence of a Barrier Layer in the Sulu and Celebes Seas
Publisher: American Meteorological Society
Abstract: Variability in the surface isothermal and mixed layers of the Sulu and Celebes Seas is examined using the conductivity?temperature?depth data from the Navy's Master Oceanographic Observational Data Set (MOODS). Vertical ...
Indian Ocean Dipole Modes Associated with Different Types of ENSO Development
Publisher: American Meteorological Society
Abstract: his study identifies several modes of coevolution of various types of El Niño?Southern Oscillation (ENSO) and Indian Ocean dipole (IOD) by performing rotated season-reliant empirical orthogonal function (S-EOF) analysis ...
Dynamical Role of Mode Water Ventilation in Decadal Variability in the Central Subtropical Gyre of the North Pacific
Publisher: American Meteorological Society
Abstract: Decadal variability in the interior subtropical North Pacific is examined in the Geophysical Fluid Dynamics Laboratory coupled model (CM2.1). Superimposed on a broad, classical subtropical gyre is a narrow jet called the ...
Response of the Indian Ocean Basin Mode and Its Capacitor Effect to Global Warming
Publisher: American Meteorological Society
Abstract: he development of the Indian Ocean basin (IOB) mode and its change under global warming are investigated using a pair of integrations with the Geophysical Fluid Dynamics Laboratory Climate Model version 2.1 (CM2.1). In the ...
