In the framework of FIELMI model we explore natural conditions for deforming. The wind speed 
and direction mainly determine the ice deformation rate. 
A relationship between the wind direction and deformed ice growth rate were found. The most 
intensive ridging events occur during wind blowing from N, SE or NW (Fig. 6.). But is the 
modest correlation between the magnitude of wind speed and deformation. Then the deformed 
ice growth rate did not strongly depend on wind magnitude of speed. For example, wind speed 
over 4 m/s could cause large deformation events and sometimes deformation is very low during
