Arctic and East Asia Winter Climate Variations Associated with the Eastern Atlantic Pattern
Publisher: American Meteorological Society
Abstract: he wintertime Arctic temperature (T; surface?400 hPa) decreased from 1979 to 1997 and increased rapidly from 1998 to 2012, in contrast to the global mean surface air temperature. Here aspects of circulation variability ...
Systematic Comparison of ENSO Teleconnection Patterns between Models and Observations
Publisher: American Meteorological Society
Abstract: his paper applies a new field significance test to establish the existence and consistency of ENSO teleconnection patterns across models and observations. An ENSO teleconnection pattern is defined as a field of regression ...
Field Significance of Regression Patterns
Publisher: American Meteorological Society
Abstract: egression patterns often are used to diagnose the relation between a field and a climate index, but a significance test for the pattern ?as a whole? that accounts for the multiplicity and interdependence of the tests has ...
Eddy–Zonal Flow Feedback in the Southern Hemisphere Winter and Summer
Publisher: American Meteorological Society
Abstract: The eddy?zonal flow feedback in the Southern Hemisphere (SH) winter and summer is investigated in this study. The persistence time scale of the leading principal components (PCs) of the zonal-mean zonal flow shows substantial ...
Variability of the Southern Hemisphere Winter Split Flow—A Case of Two-Way Reinforcement between Mean Flow and Eddy Anomalies
Publisher: American Meteorological Society
Abstract: A new split-jet index is defined in this study, and composites based on this index show that the split-flow regime is characterized by a cold?warm?cold tripolar temperature anomaly in the South Pacific that extends equatorward ...
Empirical Correction of the NCEP Global Forecast System
Publisher: American Meteorological Society
Abstract: This paper examines the extent to which an empirical correction method can improve forecasts of the National Centers for Environmental Prediction (NCEP) operational Global Forecast System. The empirical correction is based ...
Hybrid Bored Prestressed Concrete Cased Piles: Equipment and Construction Procedures
Publisher: American Society of Civil Engineers
Abstract: To widen the applications of large-diameter prestressed high-strength concrete (PHC) piles to stiff strata, this paper introduces a novel hybrid piling technique, including the equipment and construction procedures. The ...
Summer Enhancement of Arctic Sea Ice Volume Anomalies in the September-Ice Zone
Publisher: American Meteorological Society
Abstract: AbstractBecause of its persistence on seasonal time scales, Arctic sea ice thickness (SIT) is a potential source of predictability for summer sea ice extent (SIE). New satellite observations of SIT represent an opportunity ...
A Weather-Type-Based Cross-Time-Scale Diagnostic Framework for Coupled Circulation Models
Publisher: American Meteorological Society
Abstract: AbstractThis study proposes an integrated diagnostic framework based on atmospheric circulation regime spatial patterns and frequencies of occurrence to facilitate the identification of model systematic errors across ...
Dynamical Seasonal Predictions of Tropical Cyclone Activity: Roles of Sea Surface Temperature Errors and Atmosphere–Land Initialization
