In both Brazilian and North American English, 'tidal wave' is commonly used metaphorically to describe sudden, overwhelming trends or surges in public opinion, markets, or social movements. While scientifically, the term has been largely replaced by 'tsunami' in scientific discourse, it remains prevalent in everyday language and media. In Portuguese-speaking countries, 'maremoto' is the more precise technical term, though 'onda de maré' maintains the literal translation and is widely understood.
