Most areas are located between the Tropic of Cancer and the Tropic of Capricorn, and most areas are tropical and subtropical. Australia has a maritime climate except continental climate. The average annual temperature in most areas is between 25.8℃. In the northern hemisphere, from the northernmost surface of the Hawaiian Islands to the equator, the average temperature in the coldest month rises from 16℃ to 25℃. The southern hemisphere increases from 50 south latitude to equator, from 6℃ to 25℃; The South Island of New Zealand and the mountainous areas in southeastern Australia can reach below 0℃. From the northernmost part of the Hawaiian Islands to the vicinity of the Mariana Islands, the average temperature in the hottest month in the northern hemisphere rose from 24℃ to over 28℃. The southern hemisphere starts from about 50 degrees south latitude to the northwest of Australia, and rises from 12℃ to 32℃. The extreme maximum temperature in Crockley, Queensland, Australia is 53℃, which is the hottest place in Oceania. The average annual precipitation in the desert areas of central and western Australia is less than 250 mm, which is the least in Oceania. The annual average precipitation in the northeast of Kauai, Hawaii is as high as 12 000 mm, which is one of the regions with more precipitation in the world. Northern New Guinea, Melanesia, Micronesia and Polynesia are tropical precipitation areas, which are rainy all year round, and the annual average precipitation on windward slopes exceeds 2 000 mm.. In northern Melanesia, northern New Guinea and southern Marshall Islands, the average annual precipitation can reach 3 million millimeters, while the leeward slope is only 1 1,000 millimeters ... Northern Australia and the southeast coast of New Guinea are warm season rainfall areas with an average annual precipitation of 750,000 millimeters, accounting for about 50% of the annual precipitation. Southeast Australia and New Zealand belong to temperate precipitation areas, with relatively uniform precipitation in each month, but slightly more in winter. The annual average precipitation is more than 500 mm, and it is as high as 5 000 mm in some areas. The southwest and southwest coast of Australia belong to the Mediterranean winter precipitation area, and the winter precipitation accounts for about 40-60% of the annual precipitation.
The climate in China has three characteristics: obvious monsoon characteristics, obvious continental climate and diverse climate types. In winter, the temperature is generally low, hot in the south and cold in the north, and the temperature difference between the north and the south is large, exceeding 50℃. The main reasons are: the sun shines directly in the southern hemisphere in winter, and the northern hemisphere gets less solar energy; Latitude influence: winter winds prevail in winter. In summer, the temperature in most parts of the country (except the Qinghai-Tibet Plateau) is generally high, and the temperature difference between north and south is not large. The main reasons are as follows: in summer, the sun shines directly in the northern hemisphere, and the northern hemisphere gets more heat; Summer monsoon prevails in summer, and the temperature in most parts of China rises to the highest value; In summer, the higher the height of the sun, the higher the latitude and the longer the day, which slows down the difference between the north and the south in receiving solar light and heat. The coldest place in winter is Mohe Town, and the hottest place in summer is Turpan.
