Patterns of ocean current variability on the West Florida Shelf using the self-organizing map
[1] Patterns of ocean current variability are examined on the West Florida Shelf by a neural network analysis based on the self-organizing map (SOM), using time series of moored velocity data that span the interval October 1998–September 2001. Three characteristic spatial patterns are extracted in a 3 4 SOM array: spatially coherent southeastward and northwestward flow patterns with strong curr...
متن کامل2.4 Sea Surface Temperature Patterns on the West Florida Shelf Using Growing Hierarchical Self-organizing Maps
The West Florida Shelf (WFS) is a broad, gently sloping continental margin that is influenced by the Gulf of Mexico Loop Current system located seaward of the shelf break (Molinari et al., 1977; Huh et al., 1981; Paluszkiewicz et al., 1983; He and Weisberg, 2003; Weisberg and He, 2003) and by local wind and buoyancy forcing, including the fresh water of the Mississippi River, generally found at...
متن کاملSea Surface Temperature Patterns on the West Florida Shelf Using Growing Hierarchical Self-Organizing Maps
Neural network analyses based on the self-organizing map (SOM) and the growing hierarchical selforganizing map (GHSOM) are used to examine patterns of the sea surface temperature (SST) variability on the West Florida Shelf from time series of daily SST maps from 1998 to 2002. Four characteristic SST patterns are extracted in the first-layer GHSOM array: winter and summer season patterns, and tw...
متن کاملLifestyle patterns in the Iranian population: Self- organizing map application
Background: The present study evaluated the lifestyle behavior patterns and its associations with demographic factors in the Iranian population. Methods: A total of 8244 people aged 25-70 years who participated in a national survey in 2011 were included in the study. Factors related to lifestyle (such as diet, physical activity, and tobacco use) have been collected using a questionnaire. A sel...
متن کاملNOTES AND CORRESPONDENCE Current Patterns on the West Florida Shelf from Joint Self-Organizing Map Analyses of HF Radar and ADCP Data
To assess the spatial structures and temporal evolutions of distinct physical processes on the West Florida Shelf, patterns of ocean current variability are extracted from a joint HF radar and ADCP dataset acquired from August to September 2003 using Self-Organizing Map (SOM) analyses. Three separate ocean– atmosphere frequency bands are considered: semidiurnal, diurnal, and subtidal. The curre...
