| Zusammenfassung |
| Study of heavy rain events and their spatial distribution are of great
importance. Such events cause local flooding, accelerate soil erosion and
cause damage on property. Data for this study were derived by Sokol and
Bližňák (2009) from radar reflectivity and daily rain gauge
measurements for the period of 2002–2008. We selected heavy rain events
using spatial and intensity constrains. We studied relationships between
heavy rains, altitude and terrain roughness. Heavy rain totals correlate
with both altitude and terrain roughness globally over the Czech Republic.
The correlation is also significant for extreme heavy rain totals. The
correlation of heavy rain intensities with altitude was not proven. The
highest rates of average intensities are located in the south-eastern parts
of the Czech Republic. The spatial distribution of heavy rain frequencies
strongly corresponds to the spatial distribution of heavy rain totals. The
highest percentage of heavy rains in total precipitation is located in the
north-west of the Czech Republic. The extreme heavy rains occupy higher
altitudes. |
