RISInfluences 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 ...
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 ...
Estimate of the Predictability of Boreal Summer and Winter Intraseasonal Oscillations from Observations
Publisher: American Meteorological Society
Abstract: ropical intraseasonal variability (TISV) shows two dominant modes: the boreal winter Madden?Julian oscillation (MJO) and the boreal summer intraseasonal oscillation (BSISO). The two modes differ in intensity, frequency, ...
Predictability of the Madden–Julian Oscillation Estimated Using Observational Data
Publisher: American Meteorological Society
Abstract: Existing numerical models produce large error in simulating the Madden?Julian oscillation (MJO), thereby underestimating its predictability. In this paper, the predictability limit of the MJO is determined by the nonlinear ...

The Application of Nonlinear Local Lyapunov Vectors to Ensemble Predictions in Lorenz Systems
Publisher: American Meteorological Society
Abstract: onlinear local Lyapunov vectors (NLLVs) are developed to indicate orthogonal directions in phase space with different perturbation growth rates. In particular, the first few NLLVs are considered to be an appropriate ...
Predictability of Tropical Cyclone Intensity over the Western North Pacific Using the IBTrACS Dataset
Publisher: American Meteorological Society
Abstract: AbstractThe predictability limits of tropical cyclone (TC) intensity over the western North Pacific (WNP) are investigated using TC best track data. The results show that the predictability limit of the TC minimum central ...
