In this article, we apply the independent component analysis technique for mining spatio-temporal data. The technique has been applied to mine for patterns in weather data using the North Atlantic Oscillation (NAO) as a specific example. We find that the strongest independent components match the observed synoptic weather patterns corresponding to the NAO. We also validate our results by matchi...

heavy rains are one of the features of arid and semi arid climates which result in flood. this kind of rainfall originates from environmental and synoptic conditions. mediterranean cyclones are the major factor in heavy rainfall in iran, but these cyclones do not happen in some parts of iran such as southern and southeastern areas. in this study, it has been tried to pinpoint the synoptic reaso...

abstract the averages of monthly minimum temperature and wind speed in 32 synoptic stations in northwest and west of iran used for calculate windchill temperature from november to april. then maps of spatial differences were drawn for every month and windchill regions classified by cluster analysis. keywords: iran, windchill, regionalization, classification.
