What's the difference between the climate in China and Sydney?

Sydney has a subtropical humid climate with abundant annual rainfall. The weather in Sydney is influenced by the adjacent ocean, so this western inland city is more continental. The warmest month is 65438+1October, the temperature in coastal areas is18.6℃–25.8℃, the average number of days above 30℃ is 14.6 days, and the highest recorded temperature is 45.3℃,1939 65438+. It is slightly cool in summer, and the temperature in coastal areas rarely drops below 5℃, the highest in Leng Yue is July, with the average extreme value of 8.0℃- 16.2℃ and the lowest recorded value of 2. 1℃. The rainfall in Xia Dong is quite uniform in two seasons. Due to the adjustment of the east wind, the rainfall in the first half of the year was slightly higher. The average annual rainfall is 12 17.0mm, with moderate rainfall and little change, and the average annual rainfall is 138.0 days. 1830, it snowed in Sydney.

Although Sydney will not encounter cyclones or major earthquakes, El Ni? o phenomenon or El Ni? o Southern Oscillation is affecting the weather conditions in Sydney: on the one hand, there are droughts and forest fires, on the other hand, there are storms and floods, which are all combined with oscillation. Forest fires have occurred in many areas near the forest in Sydney, especially in 1994 and 2002-forest fires often occur in spring and summer. Sydney is prone to rare hail and storms.

China is very big and the climate is very complicated. Here, Beijing, Shanghai and Haikou are selected for comparison:

Beijing's climate: The main feature of Beijing's climate is four distinct seasons. Dry in spring, hot and rainy in summer, refreshing in autumn and cold and dry in winter; The wind direction has obvious seasonal variation, with northwest wind prevailing in winter and southeast wind prevailing in summer. The climatic characteristics of the four seasons are as follows:

Spring: the temperature rises quickly, the temperature difference between day and night is large, and it is dry and windy. In spring, with the gradual increase of the sun's altitude angle, the daylight time is prolonged, and the heat obtained on the ground exceeds the expenditure, so the temperature rises rapidly. The monthly average temperature can be increased by 9-6℃, the average temperature is 4.5℃ in March and 13. 1℃ in April. The daytime temperature is high, the nighttime radiation cooling is strong, and the temperature is low, which is the season with the largest temperature difference between day and night. The average daily temperature difference is 12- 14℃, and the maximum daily temperature difference is 16.8℃. In addition, cold air activities are still very frequent in spring, and due to the severe cooling, there is "late spring cold" weather, which is easy to form late frost. There are many windy days, and the windy days of magnitude 8 or above account for 40% of the total days of the year. When strong winds appear, they are often accompanied by floating dust, sand blowing and sandstorm weather. The scarcity of precipitation in spring aggravated the spring drought, which is called "ten years and nine spring droughts".

Summer: Summer is hot and hot, and precipitation is concentrated, forming the same season of rain and heat. In summer, except in mountainous areas, the average monthly temperature in plain areas is above 24℃. Although the hottest month is not June, the extreme maximum temperature mostly appears in June. July is the hottest month in a year, with an average temperature close to 26℃, a continuous and stable high temperature and a small temperature difference between day and night. Summer precipitation accounts for 70% of the annual precipitation, mostly in the form of heavy rain. So it is prone to flash floods, and the plains cause floods. Rainstorm is one of the main natural disasters in Beijing in summer. In addition, the strong thermal convection in mountainous areas has caused local thunderstorms accompanied by hail, which has caused certain losses to agriculture.

Autumn: the weather is crisp, the temperature is suitable and the light is sufficient. After autumn, the cold air in the north began to invade and the temperature dropped rapidly. Therefore, the early arrival of the first frost often happens.

Winter: the cold is long. Winter lasts for five months, and if the average temperature is below 0℃, it lasts for three months (1February-February). In the winter of 65438+ 10, the average temperature in the plain is below -4℃, in the mountainous area it is below -8℃, and the extreme minimum temperature in the plain is -27.4℃. Winter precipitation accounts for 2% of the annual precipitation, and there is often no record of precipitation (snow) for more than one month. Although it is cold and dry in winter, there is plenty of sunshine, averaging more than 6 hours a day, which creates favorable conditions for the development and utilization of solar energy.

Shanghai climate: Shanghai is located in the eastern part of the Yangtze River Delta where rivers and seas meet, in the north subtropical region where the East Asian monsoon prevails, and belongs to the north subtropical monsoon climate. Affected by the advance and retreat of the winter and summer monsoon, the northwest wind prevailed in Shanghai from June165438+1October to February of the following year, with a cold and dry climate, and the southeast wind prevailed from April to August in summer, which was warm, hot and humid. However, under the direct control of the subtropical high in the northwest Pacific, southwest winds sometimes blow in July and August, and the weather is hot and dry. March and early September to 10 are the transition seasons of monsoon transition, with northeast wind and east wind as the main winds, with more low temperature and rainy weather.

The main climatic characteristics of Shanghai: Leng Xia is hot in winter, with four distinct seasons, but there are often cold currents in winter; In the same season of rain and heat, there is abundant precipitation, but the variability is large; Light and temperature are coordinated, and there are many sunshine, but it varies from year to year. According to Shanghai meteorological data statistics (1873 ~1994); The annual average temperature is 15.5℃, the coldest in June is 1, and the average temperature is 3.4℃. It is the hottest in July, with an average temperature of 27.5℃. The frost at the end of April 1,1the frost at the beginning of October 1 16, with an average frost-free period of 228 days. The active accumulated temperature above 10℃ is 4934℃/ day, which is second only to Sichuan Basin and the south of Hangzhou, Anqing, Wuhan and Yichang. Average annual precipitation 1 149.8 mm, precipitation days 13 1 day. The average monthly rainfall from April to September is above 100 mm, and the total rainfall in these six months accounts for about 70% of the total rainfall in the whole year. June and September are two obviously rainy months.

The monthly rainfall in June reached more than 150 mm, which was caused by plum rain and autumn rain (including tropical cyclones) respectively. The sunshine in each month is above 150 hours, and there are more sunshine in July and August, reaching 25 1 and 260 hours respectively. In June 5438+10, the climate was cool, sunny and rainy, and the temperature difference between day and night was large.

Generally speaking, the climate in Shanghai has three characteristics.

First, Leng Xia is hot in winter with four distinct seasons, but there are often cold currents.

Second, in the same season of rain and heat, there is abundant precipitation, but the change range is large.

Third, the light and heat are coordinated, and there is more sunshine, but it is changeable all year round.

Climate of Haikou: Haikou is located at east longitude19 57 ′ 04 ″-20 05 ′1″, east longitude1/kloc-0 ′18 ″. It borders Qiongzhou Strait in the north, facing the mainland across 18 nautical mile, bordering Qiongshan City in the southeast and Chengmai County in the west. Haikou City is located in the northern edge of the tropical zone with low latitude and belongs to the hot monsoon climate zone. The annual average temperature in Haikou is 23.8, the highest average temperature is 28.0 and the lowest average temperature is 18.8. The frost-free period is 346 days, and there is no ice and snow all year round. The annual average sunshine hours are 2225.2 hours.

Australian humanities: local customs: Australians have both hearty westerners and reserved orientals. They have a wide range of interests and like sports, such as surfing, windsurfing, horse racing, fishing, bocce, Australian football and swimming.

The aborigines living in Australia still protect their customs. They hunt for a living, and boomerang is their unique hunting weapon. Many of them still live in shacks made of branches and mud, surrounded by a piece of cloth or kangaroo skin, and like to get tattoos or paint various colors on their bodies. Usually only some yellow and white colors are painted on cheeks, shoulders and chest, and they are painted all over the body on holidays or festivals. Tattoos are mostly thick lines, some like raindrops and some like ripples. For the indigenous people who have passed the rite of passage, tattoos are not only for decoration, but also for attracting the love of the opposite sex. At the carnival dance, people wore colorful decorations and painted colorful patterns, and danced in groups around the bonfire. Dance is simple, reflecting hunting life, etc.

With the changes of the times, some indigenous people gradually left the tribe and moved to the city to live. Australia has various preferential policies for indigenous people, including providing them with all kinds of necessary assistance in housing, employment and welfare. In tourist areas, the artworks and handicrafts of indigenous people are one of the items collected and purchased by tourists all over the world, and they are the source of income for indigenous people.

Australia has a particularly strong atmosphere of freedom. People are commensurate with their first names (only first names, not surnames), between bosses and employees, and between teachers and students. In downtown Sydney and Melbourne, it is often seen that white-collar workers or working girls in fashionable suits get together with friends and colleagues at noon on weekdays and sit on the steps in front of buildings to have a simple lunch, such as sandwiches or hot dogs. White-collar workers are also modern metropolises, and the same scene is unimaginable in places like Tokyo or Hong Kong.

Australians are polite and helpful. If you walk on a sparsely populated street, people will say hello even if they don't know each other. If you walk down the street with a bag of fruit in your hand, the bag breaks and the fruit rolls on the ground. People around you will immediately pick it up for you and give it back to you. Someone will also find you a good bag or box, which can be used as an emergency substitute. This is Australia.

Australian life characteristics Working in Australia, wages are generally paid once a week (once every two weeks for civil servants or large institutions), and the days of paying wages are generally every Thursday or Friday. Therefore, restaurants, bars and department stores in Australia are particularly good business days every Friday and Saturday. In recent years, some large department stores and shopping centers have extended their business hours every Thursday night to cater to those who get paid every Thursday. Some people who don't pay attention to spending money will be rich on weekends and poor at the beginning of the week. It doesn't matter, because in a few days, it will be another happy weekend.

Cultural Australia is an immigrant country, and multiculturalism is an inevitable feature of Australian culture. Immigration and multiculturalism have injected vitality into this country. The Australian government encourages Australians of different races or nationalities, including indigenous people, to use their mother tongue as English at home or in public places, and also encourages people of any background and nationality to preserve their own culture. The Australian federal government even provides various kinds of assistance and subsidies to reward individuals, groups and organizations that develop multiculturalism.

From the perspective of mainstream culture, Australia belongs to western culture; Its lifestyle is similar to that of Western Europe and North America. Life in Australia is mostly relaxed and friendly, and most immigrants from all over the world like the life full of opportunities here.

Although Australia is often described as a country dominated by rural areas, in fact, it is still dominated by urban culture and cosmopolitan lifestyle, including delicious food from all over the world.

Australians like to drink beer. In their spare time, especially on weekends, many people like to go to bars to drink and chat with friends, enjoy music, or barbecue in the park. Australian cities give people an open feeling, with many open parks and green spaces dotted among them. Most parks in Australia are free. There is no fence in the park, and there are paths in and out of the park in all directions. Convenient transportation can also easily bring people into national parks on the outskirts of the city.
