	<abstract content_type="html">A precipitation event of unprecedented intensity took place over northern
part of Israel during 4 December 2001&amp;ndash;5 December 2001. The case was
associated with formation of a Cyprus Low cyclone over the Asia Minor. In
the current study the synoptic developments over the eastern part of the
Mediterranean region are simulated with the MM5 nonhydrostatic model and
analyzed based on dynamic tropopause patterns calculated from the simulation
results. According to the results, a powerful potential vorticity (PV)
streamer system played a major role in the process over the southeastern
Mediterranean region. The PV streamer created conditions for seclusion of
moist air masses from the equatorial East Africa and Atlantics during the
cyclone development. Condensation of the moisture, associated with the
latent heat release processes have contributed to the intense thunderstorm
activity and heavy precipitation of the event.</abstract>
