The correct answer is option 3 - Typhoon. A tropical storm in the Chinese Sea is known as a typhoon. A typhoon is a type of tropical cyclone that forms over the Northwestern Pacific Ocean, including the South China Sea. It is a large-scale weather system characterized by strong winds and heavy rain. Typhoons are similar to hurricanes and cyclones, but they are specifically referred to as typhoons in the Western Pacific region. These storms can cause significant damage to coastal areas, resulting in flooding, landslides, and destruction of infrastructure. It is important to note that although a typhoon and a cyclone are both types of tropical storms, they are given separate names depending on the region where they form.
