What meteorological disasters are there in Weihai?

Question 1: What are the main meteorological disasters? Types of Meteorological Disasters in China

Drought is the main meteorological disaster in China. In some areas, although there are certain moisture conditions and even abundant precipitation, which can meet the needs of a large number of people and economy, if the precipitation is abnormally low for a long period of time (months or even years), it will not be enough to maintain the people's living and production needs in this area, resulting in economic losses and even death. This is the so-called drought event. Drought is widely distributed, not only in rainy areas but also in semi-arid areas.

Drought is the largest meteorological disaster in China, with the widest and most serious impact. Drought is widely distributed in China, but the degree is different. Relatively speaking, droughts are most frequent in North China, Loess Plateau, Hexi Corridor and Sichuan Basin.

Drought will also cause some secondary disasters, such as forest and grassland fires and pests and diseases in agricultural and forestry disasters; Soil desertification in geological disasters.

Rainstorm is one of the main meteorological disasters in China. In ancient books of China, continuous rainstorm is usually recorded as "rain" and "rain". "Intermittent rain is like a note" and "continuous rain" is a continuous rainstorm. Rainstorm is one of the meteorological disasters. It is a large amount of accumulated water caused by long-term precipitation or instantaneous heavy precipitation (such as rainstorm, heavy rainstorm), which leads to flash floods, river flooding and waterlogging, resulting in crop failure or failure, traffic and communication obstruction, shipwreck, human and animal diseases and casualties. This kind of disaster is called rainstorm.

China is one of the countries with more rainstorms in the world, with concentrated rainfall and high intensity. Especially in northern China, rainfall often reaches or exceeds the annual average rainfall within a few days.

China has a vast territory and complex terrain, and most areas belong to a typical monsoon climate, so the distribution of rain and waterlogging has obvious regionality and timeliness. Rain and waterlogging mainly affect the eastern and southern regions of China, especially the east of Daxing 'anling-Taihang Mountain-Wuling Mountain. There is little rain in the west of China, and only Sichuan is a rainy and waterlogged area. The temporal distribution characteristics of rain and waterlogging in China are early in the south and late in the north.

The secondary disasters of rain and waterlogging are: pests and diseases in agricultural and forestry disasters; Collapse, landslide and debris flow in geological disasters; Flood, waterlogging, huge waves and storm surges in hydrological disasters.

◆ Tropical cyclone is one of the major meteorological disasters in China. It is a cyclonic vortex that occurs in tropical or subtropical oceans. Because of different regions, the names are different. Typhoons occur in the Pacific Northwest and the South China Sea. Hurricanes occur in the Atlantic Ocean, the Gulf of Mexico, the Caribbean Sea and the eastern North Pacific Ocean. Occurring in the Indian Ocean and the Bay of Bengal is called a "tropical storm"; Australia calls tropical cyclones "powerful?" Power. " According to the regulations of China Meteorological Bureau, China renamed "Typhoon" as "Tropical Cyclone".

Although tropical cyclones have different names in different places, they do the same harm. It is not only human life and property and huge wind speed, but also its huge waves, heavy rains and storm surges are extremely destructive, so it is a very destructive weather system.

There are about 60 tropical storms (including typhoons and hurricanes) around the world every year, of which about 76% occur in the northern hemisphere. China is one of the few countries most seriously affected by tropical cyclones in the world. On average, there are about 7 tropical cyclones landing in China every year, which mainly affect Wuyi Mountain, east of Taihang Mountain, especially the southeast coast and sea area.

Typhoon was called "hurricane" in ancient China. It is the main source of precipitation, wind disaster, tidal disaster and flood in the coastal areas of China. Therefore, tropical cyclones have both advantages and disadvantages. On the one hand, tropical cyclone process can bring abundant precipitation and alleviate local drought. On the one hand, there are many secondary disasters caused by tropical cyclones, such as collapse, landslide and debris flow in geological disasters; Flood, waterlogging, huge waves and storm surges in hydrological disasters.

◆ Cold wave and freezing disaster

? Cold wave: It is one of the major meteorological disasters in China. It is a strong cold air accumulated in high latitudes, which quickly invaded China southward, causing a wide range of severe cooling, accompanied by strong winds, rain and snow, freezing and other disasters. This weather process is called cold wave or strong cold air. Cold wave is the main meteorological disaster affecting China, which lasts from September to May of the following year, and the severe seasons are spring and autumn.

? Freezing disaster: when the temperature drops abnormally, it often causes human and animal casualties, and many objects are deformed and broken, which leads to some accidents, resulting in human and animal casualties and economic losses. This phenomenon is called freezing disaster.

Freezing injury is also the main meteorological disaster in China. ...................................................................................................................................................................... & gt

Question 2: Where is Weihai in Shandong Province? Weihai is the first national health city in China, the first batch of national environmental protection model cities and the first batch of excellent tourist cities in China. It enjoys the honorary titles of National Garden City, National Model City for Environmental Protection, National Excellent City for Comprehensive Improvement of Urban Environment, and National Top Ten City for Afforestation and Greening, and has been identified by the United Nations as the best demonstration city for improving the living environment in the world. Weihai is located at the easternmost tip of Shandong Peninsula, between 36 465 438+0 ′ and 37 35 ′ north latitude and 65 438+01kloc-0/′ ~122 42 ′ east longitude. Surrounded by the sea on three sides, it is connected with the land on one side, facing the corner of Liaodong Peninsula in the north, facing the Korean Peninsula and the Japanese archipelago across the sea in the east and southeast, and bordering Yantai and Qingdao in the west, which governs Rongcheng City, Wendeng City, Rushan City and Huancui District. The city has a total area of 5463 square kilometers and a total population of 2.47 million, of which the urban area is 73 1 000 square kilometers and the population is 522,000. The flower in Weihai is osmanthus fragrans, and the city tree is acacia.

Weihai belongs to temperate continental monsoon climate, which is characterized by warm winter, cool summer, cold spring and warm autumn. The annual temperature changes little; The rainfall is moderate, but the distribution is uneven; Meteorological disasters such as drought, flood, wind and hail, low temperature and frost occur from time to time. The annual average temperature 1 1.4℃, precipitation 793.2mm, sunshine time 2570 hours.

Weihai used to be a noisy place in the East, Qingzhou in Xia and Shang Dynasties and Lai Ci in Zhou Dynasty. The Spring and Autumn Period and the Warring States Period belong to Qi. The Qin Dynasty belonged to Qi. The Han Dynasty belongs to Donglai County of Qingzhou, and the Three Kingdoms belong to Changguang County of Qingzhou. From the Western Jin Dynasty to the Sui Dynasty, it changed frequently, belonging to Mu Ping County in Donglai and Changyang County in Qingzhou, Dongmou County in Dongmou County, Guanyang County and Mu Ping County in Dongmou County in Guangzhou. The Tang Dynasty successively belonged to Dengzhou, Laizhou and Penglai. The Five Dynasties and the Song Dynasty followed the Tang system. Jin Yuan changed to Ninghai House. Ming belongs to Ninghai Prefecture, Laizhou Prefecture, Ninghai Prefecture and Dengzhou Prefecture. In the thirty-first year of Hongwu (1398), Ahava, Chengshanwei and Jinghai Wei were established, and 3 Wei belonged to Shandong Capital. At the beginning of the Qing Dynasty, it belonged to Ninghai Prefecture and came to Qinglu Prefecture. In the third year of Yongzheng (1725), 3 Wei was changed to Dengzhou. In the 13th year of Yongzheng (1735), Shanwei was changed to Rongcheng County. 1898, Ahava was forcibly occupied by Britain. 1930 10 in June, China regained Ahava. After 1934, it belongs to eastern Shandong, the seventh administrative region and eastern Shandong. Rongcheng and Wendeng were liberated in 1940, belonging to Jiaodong Administrative Region of Shandong Province. 194 1 year, belonging to the East China Sea. 1In August, 945, Ahava City (prefecture-level) was established, directly under Jiaodong Administrative Region, and changed to a county-level city, under the jurisdiction of Donghai District. The calendars from 1950 to 1982 belong to Wendeng, Laiyang, Yantai and Yantai. /kloc-In 0/9, Weihai City (now Huancui District) was changed to a county-level city under the provincial jurisdiction, which was managed by Yantai City, and Wendeng, Rongcheng and Rushan counties were under the jurisdiction of Yantai City. 1987 Weihai was upgraded to a prefecture-level city, and Huancui District was established. Rongcheng, Wendeng and Rushan in Yantai City are under the jurisdiction of Weihai City.

Weihai is rich in tourism resources, including urban landscape, island scenery, beach rocks, folk customs, underground hot springs, cultural relics, famous ancient temples, strange rocks and rivers, etc. More than 80 scenic spots, such as Liu Gongdao, the famous memorial site of the Sino-Japanese War of 1894-1895, Shengjing Mountain, the sacred waterscape of Xanadu, Tiecha Mountain, Chishan Fahua Garden, which embodies the friendship among the people of China, Japan and South Korea, and Swan Lake, the largest swan wintering place in the north of our garden, depict the beautiful scenery of Weihai with a total area of 5,436 square kilometers. In recent years, Weihai Film and Television City, Xixiakou Wildlife Park, Shengjingshan Sightseeing Cableway, War of Resistance against Japanese Aggression Museum and other tourism projects have been newly built, as well as four provincial-level tourist resorts such as Huancui, Yintan, Shidaowan and Swan Lake.

Question 3: Why are the resources in Weihai the most suitable for human habitation? Weihai, located at the easternmost tip of Shandong Peninsula, is the easternmost coastal city in China. It is one of the coastal open cities in China, the first batch of "national health cities", the first batch of "national environmental protection model cities" and the first batch of "excellent tourist cities in China" in China. It was twice rated as "the best example city for improving the living environment" by the United Nations, and was awarded as "the living city" by the United Nations in 2003.

Weihai is located at east longitude1211'-kloc-0/2242' and north latitude 36 4 1'-37 35', just on the bisector of China, with an annual average temperature of 65438+. Weihai coastline 1 000 km, accounting for about 1/3 of Shandong province. The urban area is surrounded by mountains and seas and has a beautiful environment. Weihai is a good place for tourism, summer vacation and recuperation. Weihai is one of the most dynamic cities in China. Since Weihai was founded on 1987, the city's GDP has increased at an average annual rate of 18, and it has become one of the top 50 cities in China.

Weihai is one of the earliest foreign trade ports in China. In recent years, foreign economic and trade cooperation has developed rapidly, and the added value of import and export trade has reached more than 30%. World-renowned multinational companies such as Samsung, Mitsubishi, Itochu, Merrill Lynch, Horton, Invisible and JT have invested in Weihai. Weihai is increasingly becoming an ideal place for foreign investment, with complete infrastructure and perfect investment service system. It is one of the 40 cities with excellent investment environment in China.

Weihai has beautiful scenery and four distinct seasons. It is a tourist summer resort with mountains and seas. 1996 weihai was rated as one of the global 100 demonstration cities for improving human settlements by the united nations. Weihai is the first national health city in China, the first batch of national environmental protection model cities and the first batch of excellent tourist cities in China.

Question 4: What are the severe natural disasters such as typhoon, rainstorm, drought, cold wave, sandstorm, earthquake, debris flow and tsunami?

Question 5: What are the natural disasters in recent years? April 2005 1 day14: 35 The 2004 Indian Ocean earthquake occurred at 00:58:55 UTC on February 26, 2004 (07:58:55 local time in Jakarta and Bangkok). The epicenter was located at the bottom of the sea in northern Sumatra, Indonesia. The intensity measured by the local seismological bureau is 6.8 degrees on the Richter scale, while the intensity measured by Hongkong, Chinese mainland and the United States is 8.5 to 8.7 degrees on the Richter scale. Subsequently, the Hong Kong Observatory and the National Earthquake Information Center revised the intensity to 8.9 degrees and 9.0 degrees respectively. This is the strongest earthquake since the Good Friday earthquake in Alaska in 1964 and the fourth strongest earthquake since 1900. Tens of thousands of people died in the tsunami triggered by the earthquake, and the tsunami in some areas was as high as ten meters (33 feet).

The earthquake and its tsunami caused huge casualties in Southeast Asia and South Asia, as far away as Oman in the Persian Gulf, Somalia, Mauritius, Reunion and other island countries on the east coast of Africa. There are about 1 10,000 deaths in India, more than 40,000 deaths in Sri Lanka, the total death toll in Indonesia may be as high as 200,000, and the number of injured people may be as high as 30,000.

On August 25, 2005, Hurricane Katrina hit the United States, killing more than 65,438+0,200 people, making it the most serious hurricane affecting the United States since 65,438+0,928. 6543810.8, a strong earthquake measuring 7.6 on the Richter scale occurred in Kashmir controlled by Pakistan, which killed 73,000 people in Pakistan, injured nearly/kloc-0.30 million people and left 2.8 million homeless. According to the data released by the World Meteorological Organization on June 5438+February 15, the extreme weather conditions such as global drought, flood and hurricane in 2005 were more serious than before.

Question 6: Is there a simple way to treat hemorrhoids and sleep? Spread it evenly as far as possible, and don't eat anything that gets angry 1

Question 7: Why did an earthquake happen in Weihai? Cause analysis of weihai earthquake.

There are two seismic zones in Weihai area. One is the Penglai-Weihai seismic belt along the northern coast of Shandong Peninsula, which extends in the northern waters of the peninsula, and the coastal topography of the northern peninsula is affected by this fault.

More than 80 years ago, Mr Weng Wenhao, a geologist, put forward the concept of "boarding subsidence zone", arguing that the northern part of the peninsula is controlled by fault structures, and crustal collapse may lead to earthquakes. Collapse is a long geological process, and there is a recorded Penglai earthquake of magnitude 7 1548 on this fault zone. There are many minor earthquakes that did not cause damage after Weihai earthquake with magnitude 6 1948. Part of this fault zone passes through the urban area of Weihai, forming a valley between Naigu Mountain and Gumodun, and extending to Baoquantang. Baoquantang is controlled by this fault, which makes the hot water in the deep crust rise to the ground along the fault to form hot springs. In a sense, hot springs are related to earthquakes. Therefore, before the earthquake, hot springs often have earthquake precursor reactions, reminding people that there are anomalies underground and there may be earthquakes.

The other seismic belt is the Mu Ping-Rushan seismic belt, which runs in the north-south direction, along the Mu Ping-Rushan line, and the north and south ends extend to the sea. It is smaller than the previous earthquake zone, and an earthquake with M = 6 of 1046 occurred in this earthquake zone. 1939 Rushan M5.5 earthquake caused different degrees of disasters. In recent years, there have been many strong earthquakes of magnitude 4 or so in this earthquake zone, which also caused slight damage to buildings and brought panic to residents.

These two seismic zones are the key parts of earthquake monitoring in this area. The intersection of the two faults is roughly in the northwest sea area of Weihai, which is an earthquake-prone area with little annual seismic activity and is also a key earthquake monitoring area.

There have been many destructive earthquakes in Weihai's history, but the general impression is that there are many small earthquakes, about magnitude 4, which will occur once every three to five years and will continue to shake for many times, which may last for three to five days. Experts call them small earthquake swarms.

During an earthquake, people usually feel the ground shaking, or hear the noise coming from underground, and get scared, which will also cause slight damage to buildings. In recent years, such small earthquakes have occurred in Weihai, Rongcheng Chengshantou and Rushan.

There is also such a record in historical materials: "On the 23rd day of the first month in the sixth year of Yongle, there was an earthquake in Dengzhou, which sounded like thunder. By the end of June, 65438+February, there was a major earthquake and numerous minor earthquakes. In the seventh year, the earthquake resumed on the 20th day of the first month, and ended in March of 14 (Guangxu's Records of Dengzhou Prefecture). The earthquake lasted for more than a year, and it is impossible to count how many earthquakes have occurred.

Several major earthquakes in the history of Weihai area;

1. A.D. 1046 (the sixth year of the Northern Song Dynasty) flew down.

According to historical records, "in March of the sixth year of Qing Dynasty, Gengyin and Dengzhou earthquakes, flying sauce naturally shook, and the sound of the sea floor thundered every time (History of Song Dynasty, volume 67)." "In the state of fly sword linhai. The big stones in the mountains have fallen into the sea, so it has been more than 50 years, and the natives are used to it and don't know what it means (Shen Cunzhong's Meng Qian Bi Tan). "

The earthquake dropped all the big stones on the mountain into the sea, and thunder kept coming from the bottom of the sea. The earthquake lasted intermittently for more than 50 years, and the local residents did not agree. This flight is full of mountains, dense forests, steep coasts, rugged rocks and clouds. Now it has been opened up as a tourist attraction. The boulder that fell on the hillside due to the earthquake is still clearly visible. The boulders in the valley are built on the ground, and you can feel the thrilling scene of the earthquake that year. It is because of the earthquake that flying rocks is more dangerous. This reminds people of Zhang Song, a beginner of the Qing Dynasty and a native of Rushan more than 300 years ago. He flew down from the space capsule and happily covered his bones with eight glasses of water. The beast squatted and stood, pulling the ground and leaning on the sky, with a thousand shapes, clean and sonorous. "

1998, the author participated in the investigation of this historical earthquake. Fortunately, a stone tablet of the Song Dynasty was found in Xiachu Town of Rushan, engraved with 1086 "Que Tuo Stone Tablet", which actually recorded the earthquake: "There is a famous mountain peak in the west, swaying on all sides and low on all sides." This can be confirmed by the records in the History of Song Dynasty. How delightful, this earthquake monument naturally became a cultural relic with historical value, and was later collected by the then Rushan County Cultural Relics Management Office.

2. 1668 (the seventh year of Kangxi in Qing dynasty) earthquake.

The epicenter of the earthquake was in Tancheng County, southern Shandong Province, and the Jiaodong Peninsula was only affected, and the disaster was extremely serious. According to historical records, "On June 17, the seventh year of Kangxi, there were three strong earthquakes, and the houses on the city walls collapsed (Yongzheng's Wendeng County Records)." "25th day of the first month of the seventh year of Kangxi, southwest ... >>"

Question 8: It will snow in Weihai in May. Does the abnormal weather portend any natural disasters? The revenge of nature and the destructive exploitation of local resources by developing countries have directly affected the climate and environment, which indicates that there will be natural disasters this year.
