1. The classification of typhoons is as follows: There are 6 levels of typhoons, from low to high, they are tropical depression, tropical storm, tropical storm, typhoon, strong typhoon and super typhoon. Typhoons are divided according to the strength of the wind, the higher the wind level, the higher the typhoon level. Wind refers to the mechanical force derived from the wind, which is simply explained as the force of the wind. The wind rating is based on the speed of the wind. The faster the wind speed, the higher the wind rating.
2, tropical depression: the wind near the center reaches 6 to 7, or the wind gust above 7. Tropical Storm: CenterWinds near Force 8 to 9, or force 9 gusts and may persist. Severe tropical storm: Winds near the center reach force 10 to 11, or force 11 gusts and may persist. Typhoon: Winds of 12 to 13 near the center, or gusts of 13 and may persist.
3. A typhoon is a type of tropical cyclone whose classification is usually based on the maximum wind speed near its center. There are generally four levels, including tropical depression, tropical storm, severe tropical storm and typhoon. Typhoons are classified as follows: Tropical Depression When the winds reach 6 to 7 per hour, it is called a tropical depression. This is a table.Winds are the weakest category, but still bring some rainfall and wind effects.
4, typhoon classification: super typhoon: the maximum average wind speed near the bottom center ≥50 meters/second, that is, 16 or above. Strong typhoon: The maximum average wind speed near the bottom center is 45 ~ 50. 9 m/s, that is, 14 ~ 15 level. Typhoon: The maximum average wind speed near the bottom center is 37 ~ 44 m/s, that is, 12 ~ 13.
5. Do you know how typhoons are graded? In general, the maximum wind speed around the eye or center of a typhoon reaches force 12 or aboveIt is called a typhoon and has the characteristics of large destructive power and wide range of influence. Generally speaking, tropical cyclones can be divided into two categories, strong and weak, according to the maximum surface wind speed around the typhoon eye or typhoon center.
6, typhoon classification: typhoon according to the maximum wind near its center to be divided into 6 levels from the size. Super typhoon: The maximum average wind speed near the bottom center should reach more than 50 meters/second, that is, level 16 or above. Strong typhoon: The maximum average wind speed near the bottom center is 45 ~ 50.9 meters/second, that is, 14 ~ 15. Typhoon: Maximum average wind speed near the base center 37 ~ 44 m/s, that is, level 12 ~ 13.

2, the meaning of typhoon refers to a tropical cyclone generated on the tropical ocean, with a large range and strong wind. Typhoon is an atmospheric vortex that exists in the tropical ocean. Because of its wide range of influence and strong destructive power, it is often referred to by peoplePay attention. The following is a detailed introduction to typhoon related knowledge. The formation of typhoons is closely related to the water vapor and heat of the tropical oceans.
3. Knowledge about typhoons in high school geography is as follows: The formation of typhoons. Typhoons are tropical cyclones that occur in the western Pacific Ocean of the northern hemisphere. The conditions for typhoon generation mainly include the following: a broad ocean surface with a water depth of more than 60m; The water surface temperature exceeds 25 degrees Celsius or above; Geostrophic deflection force; There is a tropical cyclone. Spatial and temporal characteristics. Typhoons (hurricanes) do not occur all year round, nor do they occur everywhere in the world.
4, TaiwanConditions for wind formation: Typhoons form in the western Pacific Ocean in the northern hemisphere and must meet the following conditions: a broad ocean surface with a depth of at least 60 meters; The sea temperature exceeds 25 degrees Celsius; Geostrophic deflection force action; A tropical cyclone exists. Temporal and spatial characteristics of typhoons: Typhoons do not exist all year round, nor are they universal. In terms of time, typhoons in the northern hemisphere mainly appear from July to October, and are rare in other seasons.
5, typhoon landfall is "the whole typhoon center moved to land." That is to say, where the typhoon center lands, it is called "typhoon landing somewhere." Because the central pressure of a tropical depression is lower than it is outside, soThe surrounding air rushes to the tropical depression, and when it rises, it supplies more energy to the tropical depression, exceeding the output energy. At this time, the air in the tropical depression rotates more strongly, the maximum wind power in the center increases, and the central pressure is further reduced.
6, when the typhoon is coming, you should check whether your preparation measures are perfect, and whether the living area is safe. Obey the arrangements of the local government and relevant departments and do not move in dangerous areas. If you are told to evacuate, do so immediately to ensure your personal safety. Close the doors and Windows tightly, check whether the doors and Windows are strong, and whether the fixtures are strong.
1. WANDA did not fail to live up to its promise and began to steadily increase its strength every time it sent reports. Just half a day later, a U.S. Air Force aircraft detected winds of 120KT, and the Air Force upgraded it to a Category 4 typhoon. On the 29th, WANDA did not feel tired at all, after strengthening 10KT in six hours to reach 145KT, finally becoming the second Category 5 typhoon of the yearEarned a title any tropical cyclone would be proud of.
2, nbsp; nbsp; nbsp; On July 26, 1956, a large low-pressure area began brewing near the Mariana Islands and moved north. Guam was overcast for several days. All the signs point to the creation of a behemoth. At that time nbsp; The JTWC has not yet been established, and the task of typhoon detection and prediction in the Northwest Pacific Ocean is jointly undertaken by the United States Air Force and Navy. But the Air Force did not immediately send planes to detect it.
3, is the real film to August 10, 2006The real events of the landing of category 17 super typhoon "Saomai" in Wenzhou, Zhejiang Province, show the difficult process of organizing and implementing the transfer of millions of people in a short period of time and minimizing the casualties caused by the disaster, and show the whole picture of the anti-Taiwan struggle. 4, this year has been 83 years old Bai Yusheng, at that time in the Tangshan City Construction Commission under the design department (now the Tangshan City Planning and Architectural Design Institute of the predecessor) work, after the earthquake transferred to the reconstruction headquarters to participate in urban planning, Tangshan local staff like him can only provide some service to the authoritative experts from all over the country to provide some service work in decision-making
