| Zusammenfassung |
| Tornadoes and earthquakes are characterised by a high variability in their
properties concerning intensity, geometric properties and temporal behaviour.
Earthquakes are known for power-law behaviour in their intensity
(Gutenberg–Richter law) and temporal statistics (e.g. Omori law and
interevent waiting times). The observed similarity of high variability of
these two phenomena motivated us to compare the statistical behaviour of
tornadoes using seismological methods and quest for power-law behaviour. In
general, the statistics of tornadoes show power-law behaviour partly
coextensive with characteristic scales when the temporal resolution is high
(10 to 60 min). These characteristic scales match with the typical diurnal
behaviour of tornadoes, which is characterised by a maximum of tornado
occurrences in the late afternoon hours. Furthermore, the distributions
support the observation that tornadoes cluster in time. Finally, we shortly discuss
a possible similar underlying structure composed of heterogeneous,
coupled, interactive threshold oscillators that possibly explains the
observed behaviour. |
