Large-scale patterns of isotope ratios are detectable in the tissues of organisms, but the variability in these patterns often obscures detection of environmental trends. We show that plants and animals at lower trophic levels are relatively poor indicators of the temporal trend in atmospheric carbon isotope ratios (delta13C) when compared with animals at higher trophic levels. First, we tested...

The daily weather at a particular place is largely influenced by the synoptic circulation and thermodynamic profile of the atmosphere. Heavy rainfall occurs from a particular subset of synoptic and thermodynamic states. Baseline climatologies provide objective information on heavy rainfall-producing circulation patterns and thermodynamic variables. This is how climatologically large or extreme ...

It is well recognized that the time series of hydrologic variables, such as rainfall and streamflow are significantly influenced by various large-scale atmospheric circulation patterns. The influence of El Niño-southern oscillation (ENSO) on hydrologic variables, through hydroclimatic teleconnection, is recognized throughout the world. Indian summer monsoon rainfall (ISMR) has been proved to be...

Abstract This paper describes the relationships between large-scale modes of climate variability and its related weather types with fluctuations in yield maize crops Veneto, Italy. The teleconnections analysed this work are winter North Atlantic Oscillation (NAO) summer (SNAO); West African monsoon (WAM) Intertropical Front (ITF). Despite that these indices not rigorously linked to one another,...

introduction the dynamic state index (dsi) is being introduced on the basis of a newly developed theory termed the energy-vorticity theory (evt). as a weather index, the dsi can describe the temporal sequence and intensity of areas of high and low pressure; but as a climate index, it can also diagnose climate change based on the variation in solar radiation or the influences of friction. in phy...
