What is the dominant pressure system influencing Baghdad annual precipitation pattern?

Answer 1

The dominant pressure system influencing Baghdad's annual precipitation pattern is the subtropical high-pressure system, particularly the Azores High. This system leads to dry conditions for most of the year, resulting in low annual rainfall. However, during the winter months, transient low-pressure systems from the Mediterranean can bring some precipitation, although it remains limited overall. Consequently, Baghdad experiences a semi-arid climate with most of its rain occurring between November and March.
