| Zusammenfassung |
| We investigate the dynamical behavior of multifractals in typhoons. A significant and
fascinating feature of this behavior is that it provides a proper interpretation for the pattern of
a typhoon in terms of the numerical values of its generalized dimension and scaling
exponent. For our case, these statistical quantities can be estimated numerically
from four meteorological factors, i.e., the moving speed, the central pressure, the
strong wind radius, and the maximum wind speed, before and after the landing of a
typhoon. We perform a computer simulation by using a 5-year typhoon data covering
2008 to 2012 in the East Asian region. The result from the multifractal structure
allows us to calculate a definite and reliable fractal dimension. In particular, we
discover the strength of the multifractal structures from the four meteorological factors
obtained from five years of typhoon data. The multifractal strength in the moving
speed is a relatively large compared to the other meteorological factors in three time
intervals.
