The symmetry and structural characteristics of the core of the Arabian Subtropical Anticyclone and associated surface climatology over Arabia: A spatial perspective

The Arabian High/subtropical Anticyclone (ASA) plays an essential role in regulating weather and climate in the Arabian Peninsula (Arabia) and adjacent countries. However, knowledge of the ASA and related surface conditions in Arabia is limited. Most of our knowledge comes from short-term case studies of weather events. The main goals of this climatic research are to (1) address the spatial structural and symmetry characteristics (shape, direction, intensity, and size) of the ASA core centers for Sep to Mar; and (2) examine related seven month summaries of surface weather characteristics for precipitation, temperature, wind, and particulates with diameters <2.5 μm (PM2.5) over Arabia.
