| Abstract | Research on characteristics of the near-surface wind speed time series can be of great help to understand the mechanisms of odor/gas dispersal and moreover provides useful clues for the optimization of odor/gas source localization algorithms. In this paper, an integrated technique which combines a direct identification method of chaos, i.e., the saturated correlation dimension algorithm with the surrogate data method (an indirect identification method) is proposed to analyze the chaotic characteristics of the near-surface wind speed time series. The analysis procedure includes two stages. Firstly, the GP algorithm is applied to calculate the saturated correlation dimension of the wind speed time series. The value of correlation dimension is 4.1628 ± 0.0022, which indicates that the wind speed time series probably has chaotic characteristics. Then 30 surrogate data sets of original wind speed series are generated by amplitude adjusted Fourier transform (AAFT), and saturated correlation dimension is employed as the statistic of Sigma test. Simulation experiments and numerical analysis show that some deterministic nonlinear components exist in the original wind speed time series. This conclusion provides further confirmation to our pre-assumption, i.e. the near-surface wind speed signal may have chaotic characteristics. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
