How are hurricanes and typhoons defined? What's the difference and connection?
Typhoon is a strong cyclone vortex that occurs in the tropical ocean and is always accompanied by violent storms. The low-pressure system generated and developed on the tropical ocean surface is called tropical cyclone. According to the maximum wind force classification near the center, it is generally called a typhoon above 12. Strong tropical cyclones are accompanied by violent storms, huge waves and storm surges.
The formation of a hurricane requires three conditions: warm sea water; Humid air; The wind on the ocean surface can turn the air into an inward rotating airflow. In most storm structures, the air will become warmer and warmer, and will rise higher and higher, and eventually flow to the outside atmosphere. If these upper winds are light, then this storm structure will be maintained and developed. The sky at the eye of the hurricane (that is, the center of the hurricane) is relatively calm. The most violent weather phenomenon occurs in the surrounding atmosphere near the eye of a hurricane, which is called the eye wall. At the top of the eye wall, most of the air flows out, which intensifies the upward movement of the atmosphere.
