Multi-Scale Analysis of Teleconnection Indices: Climate Noise and Nonlinear Trend Analysis
نویسنده
چکیده
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 Oscillation (NAO), the North Pacific index (NP) and the Southern Annular Mode (SAM) are analyzed.

متن کاملInvestigating the Effects of Teleconnection Indices on Net Primary Production in the North of Iran’s Alborz Mountains
One of the main scientific topics on the effects of global climate change is to assess changes in the carbon cycle in rangelands. Net Primary Production (NPP) is an important component of this cycle, in terms of carbon storage, and a key indicator for assessing the ecosystem function. This research aimed to investigate the correlation between NPP and ocean-atmospheric oscillations, monthly and ...

Nonlinear MUSA is an extension of MUSA, which employs a derived approach to analyze customer satisfaction and its determinants. It is a preference disaggregation approach, widely welcomed by scholars since 2002, following the principles of ordinal regression analysis. N-MUSA as a goal programing model, evaluates the level of satisfaction among some groups including customers, employees, etcete...
متن کاملAnalysis of Extreme Temperature Change Trend under Future Scenarios in order to Assess Climate Fluctuations (Case Study: Sanandaj and Saghez Synoptic Stations)
Climate change is a phenomenon that has affected natural ecosystems and all aspects of human life in recent years. Therefore, identifying and predicting climate change can greatly help manage it and reduce its harmful effects. The purpose of the present study is to identify whether or not occurrence of climate change by extreme indices including TXx and TNn during 1961-2015. In addition, CanESM...
