UAE: Sun Perpendicularity Begins Tomorrow; Summer Solstice Expected Next June
Ibrahim Al Jarwan, Chairman of the Board of Directors of the Emirates Astronomical Society and a member of the Arab Union for Astronomy and Space Sciences, has shed light on significant celestial events occurring between April 24th and August 20th.
During this timeframe, the sun will assume a perpendicular position relative to the Arabian Peninsula, with the apex of this phenomenon occurring between June 20th and 22nd, marking the summer solstice. Additionally, Mecca will experience the sun directly overhead at noon on May 27th and 28th, as well as on July 16th and 17th.
Al Jarwan elaborated that from June 6th to July 7th, the sun will be perpendicular to the latitude circles encompassing the southern regions of the Emirates. As a result, in these areas, the meridian shadow will disappear at noon.
The manifestation of the sun's perpendicularity will cause the noon shadow to disappear in southern regions such as Umm Al-Zamul, Jaysora, Muzaira'a, Liwa, Madinat Zayed, and Al-Qu'a. This phenomenon occurs due to the intersection of the Tropic of Cancer with the southern parts of the country. Conversely, in other regions of the country, the noon shadow will diminish, resulting in the shortest meridian shadow or the shortest duration of noon throughout the year during this period.
These celestial occurrences hold significant astronomical and cultural importance. The summer solstice, in particular, has been celebrated across various civilizations throughout history, marking the longest day of the year in the Northern Hemisphere. In the UAE, where astronomical observations and traditions are deeply rooted, these events serve as a reminder of the intricate relationship between the Earth and the cosmos while also influencing cultural practices and daily routines.
As such, Al Jarwan's insights provide valuable information for both astronomers and the general public, fostering a deeper understanding of celestial phenomena and their impacts on life on Earth.
