What it means
とあって means “because of” or “given that,” presenting the preceding circumstance as an exceptional, noteworthy, or especially relevant reason for what follows. It often implies that the result is natural or understandable in light of that circumstance. The construction is formal and is common in written language, news reports, and polished narration. It attaches to nouns, plain verb forms, and adjective forms.
Usage note
とあって is more formal and emphatic than ordinary causal expressions such as から or ので. It generally introduces a circumstance that is unusual, special, or worth mentioning, rather than an everyday reason.
