Abstract: (5565 Views)
The occurrenceof extreme climate events, including tropical
storms, annually leaves irreparable damage in areas under their control. Understanding
these events and the knowledge of the time of their occurrence can be useful in
the management of emergencies caused by them. The aim of this research is spatiotemporal
reconstruction of tropical storms affecting the southeast coasts of Iran. The
data used in this study include reanalysis data the National Center for
Environmental Prediction )NCEP) with
spatial resolution of 2° to 2° from 1871 to 2012 and the
ECMWF dataset with spatial resolution 1°. In terms of temporal frequency, the
results show that in total 30 tropical storms affected southern coast of Iran,
directly or indirectly, during 1871-2015. The highest monthly frequencies belong
to June with 21 events and July with 7 occurrences. In terms of spatial
frequency, the genesis and ultimate develop of all the detected storms was the
Arabian Sea and the latitudes of approximately 15° N. Most occurrences of storm,
which was in June, followed the Southeast-Northwest track.
