| Summary: | and rainfall rate (R), identified as Z-R relationships have been
derived to facilitate the rainfall rate estimation by weather radar.
Most of the previously proposed Z-R relationships were implied
as too generalized and only applicable within the region that has
identical climate characteristics or behavior. Based on such
notion, the most accurate Z-R relationship applicable for
Malaysian weather radar therefore needs to be investigated and
identified. In this paper, two renowned models will be evaluated
on how well they fit to Malaysian weather radar data.
Preliminary comparisons between the previously proposed Z-R
relationships using newly acquired radar data in Malaysia and
ground-based rain gauge measurements are also presented. The
use of inaccurate relationship can cause error in radar rainfall
estimates. This might pose unacceptable risk for the aviation
industry where accurate, dependable weather information
deduced by radar system is expected at all times. |
