The impact of synoptic-scale atmospheric circulation on the urban heat island effect over Athens, Greece

The effect of the synoptic scale atmospheric circulation on the urban heat island phenomenon over Athens, Greece, was investigated and quantified for a period of two years, using a neural network approach. A neural network model was appropriately designed and tested for the estimation of the heat island intensity at twenty-three stations during the examined period. The day-by-day synoptic scale atmospheric circulation in the lower atmosphere for the same period was classified into eight statistically distinct categories.
