A Cut-off low at 500 hPa Geopotential Height and Rainfall Events over Iraq: Case Studies

A cut-off low is a closed with value of geopotential height at the upper atmospheric levels that has been fully detached (cut-off) from westerly flow and move independently. causes extreme rainfall events in mid-latitudes regions. The main aim this paper to investigate 500 hPa over Iraq synoptic point view behavior hPa. To examine association across Iraq, two case studies heavy different times were conducted. results showed will strengthen low-pressure system surface, leading instability significant amount rain fall if moisture available.
