Climate forcing in complex ecosystems can have profound implications for ecosystem sustainability and may thus challenge a precautionary ecosystem management. Climatic influences documented to affect various ecological functions on a global scale, may themselves be observed on quantitative or qualitative scales including regime shifts in complex marine ecosystems. This study investigates the po...

Simultaneously cycling space weather parameters may show high correlations even if there is no immediate relationship between them. We successfully remove diurnal cycles using spectral subtraction, and both longer (e.g., the 27 days solar cycle) with a difference transformation. Other methods of cycle removal (daily averaging, moving averages [MAs], simpler subtraction regression) are less succ...

The relentless spread of photovoltaic production drives searches smart approaches to mitigate unbalances in power demand and supply, instability on the grid ensuring stable revenues producer. Because development energy markets with multiple time sessions, there is a growing need forecasting for steps, from fifteen minutes up days ahead. To address this issue, study both short-term-horizon three...

It is well-known that causal forecasting methods that include appropriately chosen Exogenous Variables (EVs) very often present improved forecasting performances over univariate methods. However, in practice, EVs are usually difficult to obtain and in many cases are not available at all. In this paper, a new causal forecasting approach, called Wavelet Auto-Regressive Integrated Moving Average w...
