Multidecadal climate variability dominated past trends in the water balance of the Baltic Sea watershed

open access: yesnpj Climate and Atmospheric Science, 2023
The Baltic Sea watershed includes the territories of 14 countries in Northern, Central, and Eastern Europe. Long-term observations have shown that the climate in this area is characterised by a pronounced multidecadal variability, with a period of about ...

Winter-spring cyclonic variability in the Mediterranean-Black Sea region associated with global processes in the ocean-atmosphere system [PDF]

open access: yesAdvances in Science and Research, 2011
Using global NCEP/NCAR reanalysis data set on 1000 hPa geopotential height (1948–2006), cyclones in the Mediterranean and Black Sea regions were detected and their main characteristics (frequency, depth, integrated area) were calculated.

Effect of ENSO modulation by decadal and multi-decadal climatic oscillations on contiguous United States streamflows

open access: yesJournal of Hydrology: Regional Studies, 2021
Study Region: The contiguous United States (CONUS). Study Focus: This study assesses the effects of the large-scale oceanic-atmospheric oscillations such as El Niño southern oscillation (ENSO), Atlantic Multidecadal Oscillation (AMO), North Atlantic ...

Atlantic Multidecadal Oscillation modulates the relationship between El Niño–Southern Oscillation and fire weather in Australia [PDF]

open access: yes, 2023
The El Niño–Southern Oscillation (ENSO) is a crucial driver of fire weather in Australia, with the correlation between ENSO and Australian fire weather having intensified over the past 2 decades.

Heterogeneity in Spatiotemporal Variability of High Mountain Asia's Runoff and Its Underlying Mechanisms

open access: yesWater Resources Research, 2023
High Mountain Asia (HMA) is the headwater area for major Asian rivers, providing a vast amount of freshwater to billions of people in Asia. These rivers also make their surrounding areas highly vulnerable to destructive water‐related disasters.

Atlantic–Pacific Links in Observed Multidecadal SST Variability: Is the Atlantic Multidecadal Oscillation’s Phase Reversal Orchestrated by the Pacific Decadal Oscillation? [PDF]

open access: yesJournal of Climate, 2020
AbstractThe Atlantic and Pacific basin are found linked in the context of multidecadal SST variability from analyses of 118 years of observational data. Recurrent spatiotemporal variability, including multidecadal modes, was identified using the extended-EOF technique in a longitudinally global domain, allowing unfettered expression of interbasin ...

Variability of the ocean heat content during the last millennium – an assessment with the ECHO-g Model [PDF]

open access: yesClimate of the Past, 2013
Studies addressing climate variability during the last millennium generally focus on variables with a direct influence on climate variability, like the fast thermal response to varying radiative forcing, or the large-scale changes in atmospheric dynamics

Tracking Summer Greenland Blocking: The Upstream Pathway Shapes Historical Extremes and Future Change

open access: yesInternational Journal of Climatology, EarlyView.
This study investigates summer Greenland atmospheric blocking using the Lagrangian tracking Python package blocktrack applied to ERA5 reanalysis and CMIP6 models. Two types of blocks—upstream (Northern Canada origin) and retrograding (Northern Atlantic origin)—are distinguished, with upstream blocks driving recent observed frequency increasing trends ...

Extracting winter North Atlantic Oscillation information from a central European stalagmite [PDF]

open access: yes, 2013
This study explores the potential for extracting winter North Atlantic Oscillation (NAO) information from central European stalagmites using a high resolution calcite δ18O (δ18Ocal) time-series from a stalagmite (AH1) extracted from Atta cave in ...

Multidecadal trends in the nesting phenology of Pacific and Atlantic leatherback turtles are associated with population demography

open access: yesEndangered Species Research, 2014
Knowledge of the mechanisms influencing phenology can provide insights into the adaptability of species to climate change. Here, we investigated the factors influencing multidecadal trends in the nesting phenology of the leatherback turtle Dermochelys ...
