Mechanisms for the spatio-temporal development of the Tropical Pacific Meridional Mode (TPMM) are investigated using a coupled ocean-atmosphere model and observations. In both observation and the model, this meridional mode displays decadal variations and is most pronounced in spring and early summer. The model simulation suggests that once sea surface temperature (SST) anomalies in the subtrop...

The Spatio-temporal data is the description of the time, space, and attribute information of the geographic spatiotemporal process, which reflects the spatio-temporal process information of geographical phenomenon changing with the time on the earth-surface space. The spatio-temporal process information is complex and changing. Thus according to the objective of dynamic visualization of geograp...

This paper evaluates four wind retrieval methods for micro-scale meteorology applications with volume and time resolution in the order of 30 m and 5 s. Wind field vectors are estimated using sequential time-lapse volume images of aerosol density fluctuations. Suitably designed mono-static scanning backscatter LIDAR systems, which are sensitive to atmospheric density aerosol fluctuations, are ex...

Both structural and behavioral aspects need to be modeled in some spatio-temporal databases. There existing initial efforts to represent behavioral aspects of the spatio-temporal applications via events gave their priority to some local or partial behaviors rather than an overview of the system’s behavior. In this paper, an event-based approach is proposed for modeling the system’s behavior of ...

We address a fundamental question concerning spatio-temporal database systems: “What are exactly spatio-temporal queries?” We define spatio-temporal queries to be computable mappings that are also generic, meaning that the result of a query may only depend to a limited extent on the actual internal representation of the spatio-temporal data. Genericity is defined as invariance under transformat...

Evoked and coordinated brain signals often exhibit distinct, individualized spatial and temporal characteristics, such as amplitude and phase couplings across and within spatial channels. In the study of these brain potentials, it is important to characterize both the spatial and temporal morphologies of the responses for a better understanding of both the physiology and function of the brain. ...

This paper deals with spatio-temporal indexing methods for moving objects. Spatio-temporal indexing method gives a basis for data management structure for efficient search for large scale spatio-temporal data. In this paper. t\co types of indexing methods are proposed for managing spatio-temporal data for moving objects. Both methods are evaluated by computer simulation. and the merits and deme...
