| Summary: | This work evaluates the spatial features of the
synthetic rain cell profile based on two years of real rain
cells database extracted from weather radar observation
located in Kluang, Johor, Malaysia. Single rain cells
modeled by an analytical exponential and Gaussian profile
are evaluated and investigated based on certain features of
real rain cells such as maximum rain rate and root mean
square rain rate inside a single rain cell. Preliminary results
indicate the Gaussian profile with a shape factor k of 1 best
represents real single-peaked rain structures in this
particularly heavy rain area. However, the validity of results
rely highly on the resolution limitation of the database used
in this work, where the commercial operating
meteorological radar consists of coarse quantization
resolution of rain-rate, which might misinterpret the real
rain cell profile at a lower rain rate. Nevertheless, this work
still provides radio engineers with useful information for the
design of wireless communication systems in this particular
area (heavy rain region). |
