Each movement, displacement, and change in the intertropical convergence zone (ITCZ) position play an important role in atmospheric circulation and moisture provided for precipitation systems in the North East African and Middle East regions. Accordingly, the present study aimed to evaluate the role of the Arabian subtropical high pressure (ASHP) position as part of Hadley circulation in ITCZ changes in the Indian Ocean and East African region. To this end, the ASHP displacement pattern was modeled for each month with regard to the position of the central core, expansion of the first closed curve around the central core, and the last closed curve of ASHP. The evaluation of ASHP spatial displacement demonstrated that refractions along ITCZ begin early in the winter and move steeply in the range of 40° east (the south of Sudan and Ethiopia) toward the southern latitudes as the eastward and southward displacement, as well as the expansion of ASHP and its troughs. During the summer, ITCZ is placed on the north of the equator in addition to Sudan and Ethiopia, with the deployment of the ASHP central core on the eastern shore of the Red Sea as well as the orbiting of its troughs. In conclusion, the spatial displacement of ASHP and its troughs, especially at 700 hPa and above, is assumed to be a highly important factor in the northward and southward displacement of ITCZ and its significant refraction in both winter and summer in the Horn of Africa.

热带辐合带（ITCZ）位置的每一次运动，位移和变化，在东北非和中东地区的大气环流和为降水系统提供的水分中都发挥着重要作用。因此，本研究旨在评估印度洋和东非地区阿拉伯亚热带高压（ASHP）位置作为哈德利环流在ITCZ变化中的作用。为此，针对中心岩心的位置，围绕中心岩心的第一个闭合曲线的扩展以及ASHP的最后闭合曲线，每个月对ASHP位移模式进行建模。对ASHP空间位移的评估表明，沿ITCZ的折射在冬季初开始，并在向东40°（苏丹南部和埃塞俄比亚南部）向南纬的范围内急剧移动，向东和向南位移，以及扩展。的ASHP及其槽。在夏季，ITCZ除了苏丹和埃塞俄比亚之外，还位于赤道以北，随着ASHP中心核心的部署在红海东海岸及其海槽的轨道上。总之，假设ASHP及其槽的空间位移，特别是700 hPa及以上，是ITCZ向北和向南位移及其在非洲之角冬季和夏季折射的重要因素。
