THE USE OF 3-DIMENSIONAL GRAPHIC DISPLAY METHOD FOR PRESENTING THE CHANGES IN WEATHER

Several methods have been worked out by now to present the changes of weather and its elements. In this article we present a graphic method where the changes of the different elements of the weather can be analised with the help of 3D figures. The tendency of changes can be seen well from the expressive, spatial plots. During the execution of the task several models to prepare the spatial surfaces (moving average, kriging, spline, inverse distance weighting, and artificial neural network) have been used and compared. Here the daily amount of precipitation measured at the meteorological station of Szeged has been analised. For the sake of better demonstration the measurement data with the help of a digital surface model has been illustrated. In connection with this a graphic display method, with which the presentation of the tendencies in the changes of precipitation are more expressive then the ones quoted in the literature has been presented earlier. Our method is presented with displaying time series, consisting of the daily amount of precipitation of 100 years, which has meant a separate challenge, as the precipitation data show significant deviation. We have already used the presented method for the demonstration of temperature and evaporation data as well.
