RISWinter-to-Winter Recurrence of Sea Surface Temperature Anomalies in the Northern Hemisphere
Publisher: American Meteorological Society
Abstract: The spatiotemporal characteristics of the winter-to-winter recurrence (WWR) of sea surface temperature anomalies (SSTA) in the Northern Hemisphere (NH) are comprehensively studied through lag correlation analysis. On this ...
Influences of ENSO Teleconnection on the Persistence of Sea Surface Temperature in the Tropical Indian Ocean
Publisher: American Meteorological Society
Abstract: his study confirms a weak spring persistence barrier (SPB) of sea surface temperature anomalies (SSTAs) in the western tropical Indian Ocean (WIO), a strong fall persistence barrier (FPB) in the South China Sea (SCS), and ...
Contrasting Impacts of Two Types of ENSO on the Boreal Spring Hadley Circulation
Publisher: American Meteorological Society
Abstract: he possible influences of two types of ENSO [i.e., the canonical ENSO and ENSO Modoki (EM)] on Hadley circulation (HC) during the boreal spring are investigated during 1979?2010. El Niño events are featured with a symmetric ...
Temporal–Spatial Distribution of Atmospheric Predictability Limit by Local Dynamical Analogs
Publisher: American Meteorological Society
Abstract: o quantify the predictability limit of a chaotic system, the authors recently developed a method using the nonlinear local Lyapunov exponent (NLLE). The NLLE method provides a measure of local predictability limit of chaotic ...
Long-Term Trend and Decadal Variability of Persistence of Daily 500-mb Geopotential Height Anomalies during Boreal Winter
Publisher: American Meteorological Society
Abstract: An analysis has been made of the trend and decadal variability of persistence of daily 500-mb (hPa) geopotential height anomalies for the winter season. The persistence is measured based on autocorrelations at 1- and 5-day ...
Winter Persistence Barrier of Sea Surface Temperature in the Northern Tropical Atlantic Associated with ENSO
Publisher: American Meteorological Society
Abstract: his study investigates the persistence characteristics of the sea surface temperature anomaly (SSTA) in the northern tropical Atlantic (NTA). It is found that a persistence barrier exists around December and January. This ...
Space–Time Spectral Analysis of the Southern Hemisphere Daily 500-hPa Geopotential Height
Publisher: American Meteorological Society
Abstract: n this paper the authors use the NCEP?Department of Energy (DOE) Reanalysis 2 (NCEP2) data from 1979 to 2004 to expand the daily 500-hPa geopotential height in the Southern Hemisphere (SH, 90°?20°S) into a double Fourier ...
Seasonal Predictability of North American Surface Temperature Arises from SST Propagation over the Western Pacific
Publisher: American Meteorological Society
Influence of the South Atlantic Ocean Dipole on West African Summer Precipitation
Publisher: American Meteorological Society
Abstract: This paper demonstrates a causal link between the air?sea phenomenon referred to as the South Atlantic Ocean (SAO) dipole (SAOD) and the interannual variability of precipitation over West Africa during the boreal summer ...
Seasonal Forecasting of North China Summer Rainfall Using a Statistical Downscaling Model
Publisher: American Meteorological Society
Abstract: statistical downscaling model was developed with reanalysis data and applied to forecast northern China summer rainfall (NCSR) using the outputs of the real-time seasonal Climate Forecast System, version 2 (CFSv2). Large-scale ...
