In an exciting astronomical development, the Kingdom of Bahrain is set to bid farewell to summer and embrace astronomical autumn tomorrow.
Renowned astronomer Muhammad Redha Al Asfour revealed that the autumnal equinox will occur at 09:30 am local time, marking the beginning of the longest season in the Northern Hemisphere.
Al Asfour clarified that while the transition to fall won’t immediately result in noticeable weather improvements, slight atmospheric changes are expected. However, the perceived temperature may continue to rise due to high humidity.
The shift in temperature will be gradual, with moderate weather conditions anticipated only by the end of October. On the day of the autumnal equinox worldwide, the sun will rise at a 90-degree angle with the horizon from the true east point and set at a 270-degree angle from the true west point.
As the season progresses, the sun’s position will gradually tilt towards the south, resulting in vertical rays and relatively equal day and night durations on the equator. In Bahrain, day and night will be completely equal on Wednesday, September 27, 2023, with sunrise and sunset occuring at 05:28 am and 05:28 pm, respectively, and midday at 11:28.
Al Asfour explained that the onset of fall in the northern hemisphere leads to longer nights and shorter days, while the opposite occurs in the southern hemisphere, where the spring season begins, bringing longer days and shorter nights.
The occurrence of the four seasons can be attributed to the Earth’s axial tilt of 23.5 degrees as it orbits the sun in an elliptical trajectory. This tilt causes variations in the angle at which the sun’s rays hit different locations on Earth, leading to seasonal changes throughout the year.
