| Abstract: | Summary A shallow and short-lived subsynoptic cyclone is discussed as one of typical events causing natural disasters over Saudi Arabia
on 5 January 2002 using the Japan Meteorological Agency global analysis dataset. The main cause for its formation was vorticity
stretching. On the same day widespread rainfall over Saudi Arabia with enhanced precipitation over the mountainous Jeddah
region was also observed using the Global Precipitation Climatology Project dataset. Owing to eastward-moving wintertime synoptic-scale
Mediterranean disturbances, this rainfall was associated with frontal activity, modified by the local orography. |
