1, the intensity of typhoon and hurricane is different.
The intensity of typhoons is usually measured by the wind level, while the intensity of hurricanes is measured by the hurricane level. Hurricanes are usually stronger and more windy than typhoons. According to the wind speed, hurricanes are divided into five grades, from hurricane grade 1 to hurricane grade 5. The intensity of typhoon is divided into seven grades according to the wind speed.
2. The paths of typhoon and hurricane are different.
Due to the influence of the earth's rotation, the paths of typhoons and hurricanes are curved. However, typhoons usually move northwest or north-northwest, and affect East Asia, such as China and Japan. Hurricanes usually move north-northwest or west-northwest, affecting North America, Central America and the Caribbean.
3. Typhoon and hurricane have different characteristics in their development.
Typhoons usually form in tropical oceans and gradually weaken as they approach land. On the other hand, hurricanes can form in tropical oceans or subtropical regions, and have a long development process, and may maintain high intensity when approaching land.
The cause of hurricane formation:
1, ocean warmth
Hurricanes usually form in tropical oceans, and the temperature of seawater needs to reach at least 26 degrees Celsius. When the water temperature on the ocean surface rises, it will release a lot of heat energy and become the energy source in the process of hurricane formation.
2. High humidity
Humidity refers to the content of water vapor in the air, which is the source of water vapor in the process of hurricane formation. In the tropical ocean with high temperature and humidity, a large amount of water vapor will evaporate and form thick clouds. The water vapor in these clouds will condense into water droplets during the rising process, releasing latent heat and further enhancing the energy of hurricanes.
3. Updraft
In the tropical ocean, due to the heating of the surface and the increase of humidity, the air will gradually heat up and rise. When the updraft reaches a certain height, it will form a low-pressure area to attract more air to rise. As the air rises, a rotating cyclone system is formed, which is the predecessor of the hurricane.
4. Earth's rotation
Due to the influence of the earth's rotation, hurricanes usually move northwest along a certain path. This rotation effect enables hurricanes to continuously absorb more heat energy and water vapor during their movement, and enhance their intensity and scale.
