What is the extent of authenticity and reliability of the hadith that speaks of a cry (sayhah) in Ramadan followed by great events, and can it be linked to contemporary natural phenomena?

This Hadith was narrated by Nu'aym ibn Hammad in Kitab al-Fitan from Ibn Mas'ud, and its chain of transmission (sanad) is weak due to the presence of Ibn Lahia, Abd al-Wahhab ibn Husayn, Muhammad ibn Thabit al-Bunani, and al-Harith al-A'war al-Hamdani.
