Australia's climate

Australia spans two climatic zones, and the north is tropical. Every year165438+10-April is the rainy season, and165438+10-February is the dry season. Because it is close to the equator, 65438+10-February is the typhoon period.

Australia is located in the southern hemisphere. February from 65438 to February of the following year is summer with mild weather. It's autumn from March to May. It's crisp and rainy. June-August is winter, the weather is cold, and crops can grow as usual; September to 165438+ October is spring.

First of all, according to the geographical location:

One third of Australia's territory is located in the north of the Tropic of Capricorn, surrounded by a vast tropical desert climate. Tropical desert climate, the north and south sides of the ring savanna climate, the climate is quite dry. It has a humid tropical rain forest climate only in the northeast of China.

Generally speaking, it belongs to tropical climate, and the rest belongs to subtropical and temperate zones. Southwest has a Mediterranean climate, with mild and rainy winter and high temperature and little rain in summer; The subtropical humid climate is subordinate to the southeast, and Tasmania is deeply influenced by the ocean. It has a temperate maritime climate, which is warm and humid all the year round, and is a concentrated distribution area of population cities.

The whole continent of Australia, except the coastal zone, especially the southeast coast, is greatly influenced by the ocean, and the climate in most areas is dry and hot, with obvious continental nature. Under the control of downward flow, precipitation is scarce and the climate is dry, while westerly winds prevail in the southeast corner and southwest corner, with lower temperature and more rainfall.

Second, according to the season:

In summer and autumn (65438+February to May of the following year), the subtropical high zone moved southward, and the ground in the southern part of the mainland generally warmed and the climate became dry. The northern coastal area attracts warm and humid airflow, with more rain and more precipitation in the eastern coastal area.

The hottest month is 65438+ 10, and the average temperature is 29℃ in the north, 18℃ in the south, and above 30℃ in most inland areas. Near Clonkari, Queensland, the highest record is above 5 1℃. In July, the highest average temperature in Leng Yue is 24℃ in the north, 10℃ in the south and only 5℃ in the mountainous areas in the southeast.

Rainfall is scarce in most parts of the country, with an average annual precipitation of 470 mm, which is the continent with the least precipitation in the world. The regional distribution is very uneven, with abundant rainfall in the Great Watershed, the southwest corner of the mainland and the Tasmanian mountains, especially on the east coast of Queensland. The highest annual precipitation in Tali is about 4500 mm, and the annual precipitation in western Tasmania is about 3600 mm. The driest area near Lake Ayr is less than125mm. The western mainland and the vast inland areas have become arid and semi-arid areas due to insufficient precipitation and strong evaporation on the ground.
