Climate variability can affect population dynamics via adult survival or via offspring production and recruitment. The relative importance of both processes is still an unresolved matter, especially in long-lived species, where the time lags between the climate signal and the population response differ greatly depending on the process involved. We address the issue using 378 time series from 29...

The multi-scale nature and climate noise properties of teleconnection indices are examined by using the Empirical Mode Decomposition (EMD) procedure. The EMD procedure allows for the analysis of non-stationary time series to extract physically meaningful intrinsic mode functions (IMF) and nonlinear trends. The climatologically relevant monthly mean teleconnection indices of the North Atlantic O...

The aim of this study is to assess the impact of the North Atlantic Oscillation (NAO) on both the winter precipitation and the temporal occurrence of different landslide types in Portugal. The analysis is applied to five sample areas located just north of Lisbon, the capital of Portugal. These sites are particularly relevant because actual dates of most of the recent landslide events are known ...

The relationship between winter (DJF) rainfall over Portugal and the variable large scale circulation is addressed. It is shown that the poles of the sea level pressure (SLP) field variability associated with rainfall variability are shifted about 15° northward with respect to those used in standard definitions of the North Atlantic Oscillation (NAO). It is suggested that the influence of NAO o...

Recent studies show an increase in the frequency of compound extremes air temperature and precipitation many parts world, especially under dry hot conditions. Compound have a significant impact on all spheres human activity, such as health, agriculture, energy. Features atmospheric circulation are closely related to occurrence anomalies precipitation. The article analyzes relationship modes wit...

Several studies examine cycle periods and the interactions between three major climate modes over North Atlantic, namely Atlantic meridional overturning circulation (AMOC), multidecadal oscillation (AMO), (NAO). Here, we use a relatively novel high-resolution Lead–lag (LL) method to identify short time windows with persistent LL relations in series during period from 1947 2020. We find that the...

The classic 10-year population cycle of snowshoe hares (Lepus americanus, Erxleben 1777) and Canada lynx (Lynx canadensis, Kerr 1792) in the boreal forests of North America has drawn much attention from both population and community ecologists worldwide; however, the ecological mechanisms driving the 10-year cyclic dynamic pattern are not fully revealed yet. In this study, by the use of histori...

Abstract. As part of the Geoengineering Model Intercomparison Project a numerical experiment known as G6sulfur has been designed in which temperatures under high-forcing future scenario (SSP5-8.5) are reduced to those medium-forcing (SSP2-4.5) using proposed geoengineering technique stratospheric aerosol intervention (SAI). involves introducing sulfuric acid into tropical stratosphere where it ...

Abstract. Knowledge about the timing, amplitude and spatial gradients of Holocene environmental variability in circum-Baltic region is key to understanding its responses ongoing climate change. Based on a multi-dating proxy approach, we reconstruct changes productivity using total organic carbon (TOC) contents sediments Lake Kälksjön (KKJ) from west–central Sweden spanning last 9612 (+255/-114)...
