â  in order to determine the snowfall threshold temperature in different regions of kurdistan province, first the occurrence times of the non shower snow, associated with dry-bulb temperature and dew point temperature at the time of observation were extracted for 7 synoptic stations of the province. then, the frequency, relative frequency and cumulative frequency of snowfall in different temper...

The kinetics and morphology of surface growth are studied for a ballistic deposition model with two kinds of particles ~A and C! in 111 and 211 dimensions. A morphological structural transition is found as the probability of being a particle C increases. This transition is well defined by the different behavior of the surface width when it is plotted versus time and probability. The calculated ...
