Intermember Simulation Uncertainty in North Pacific Tropical Cyclone Genesis Frequency Under the Influence of the Interdecadal Pacific Oscillation at Decadal-Scale

open access: yesAtmosphere
Substantial uncertainties remain in climate model simulations of tropical cyclones (TCs), particularly those associated with internal climate variability.

Madagascar corals reveal a multidecadal signature of rainfall and river runoff since 1708 [PDF]

open access: yesClimate of the Past, 2013
Pacific Ocean sea surface temperatures (SST) influence rainfall variability on multidecadal and interdecadal timescales in concert with the Pacific Decadal Oscillation (PDO) and Interdecadal Pacific Oscillation (IPO).

THE PACIFIC DECADAL PRECESSION AND ITS RELATIONSHIP TO TROPICAL PACIFIC DECADAL VARIABILITY IN CMIP6 MODELS [PDF]

open access: yes, 2020
Persistent, multi-year shifts in atmospheric circulations and their associated influence on regional climates can have profound impacts on physical, biological, and socioeconomic systems.

How interference between the North Atlantic Oscillation and the tropical Indo‐Pacific convection modulates wave trains along the subtropical jet: Impacts on the Asian winter climate

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study reveals that the combined effects of the North Atlantic Oscillation (NAO) and anomalous Indo‐Pacific Walker circulation on the excitation of the wave train along the wintertime subtropical jet strongly depend on their phase combination. Their impacts interfere constructively or destructively over South Asia, leading to notable differences in

The changing influences of the AMO and PDO on the decadal variation of the Santa Ana winds

open access: yesEnvironmental Research Letters, 2016
Santa Ana wind (SAW) events have great implications for the environment of Southern California, but the cause of their decadal variability has not been fully understood. We show with observational analysis that the Atlantic multi-decadal oscillation (AMO)

A Tripole Index for the Interdecadal Pacific Oscillation

open access: yes, 2015
A new index is developed for the Interdecadal Pacific Oscillation, termed the IPO Tripole Index (TPI). The IPO is associated with a distinct ‘tripole’ pattern of sea surface temperature anomalies (SSTA), with three large centres of action and variations ...

Ensemble reliability and the signal‐to‐noise paradox in ECMWF subseasonal forecasts

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We derive a general expression for the ratio of predictable components (RPC) in terms of correlation, spread–error ratio, and total variance ratio. Physical constraints on the admissible solutions (i.e., real‐valued and non‐negative variances) provide a mechanism to identify statistically paradoxical sample combinations of reliability and correlation ...

Pacific Decadal and El Niño oscillations shape survival of a seabird

open access: yesEcology, 2018
AbstractUnderstanding and modeling population change is urgently needed to predict effects of climate change on biodiversity. High trophic‐level organisms are influenced by fluctuations of prey quality and abundance, which themselves may depend on climate oscillations.

Decadal-interdecadal climate variability over Antarctica and linkages to the Tropics : analysis of ice core, instrumental, and tropical proxy data

open access: yes, 2012
The Antarctic continent contains the majority of the global ice volume and plays an important role in a changing climate. The nature and causes of Antarctic climate variability are, however, poorly understood beyond interannual time scales due to the ...

Projected Temperature and Precipitation Expand Modeled Distributions of Reynoutria spp. While Modeled Distribution Changes for Ludwigia spp. Are Scenario‐Dependent at Watershed Scales in the Pacific Northwest, USA

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Invasive species can fundamentally alter their introduced habitats by changing natural processes and harming native species crucial to functional ecosystems and human needs. Although the number of potential invasive species is large, the suitability of novel locations to support population establishment is limited by both physical and ...
