China's climate memory formula is catchy.

Memory formula of climate type distribution;

The tropical rain forests in the south and north are hot and rainy in summer. Note: The air flow in the area between latitude 100 is mainly convergent, which is rainy all the year round and belongs to the tropical rainforest climate. The tropic of tropical grassland changes alternately: the tropical grassland climate is distributed between latitude 100 and the tropic of cancer, and it is controlled by equatorial depression in summer, which is hot and rainy; Winter is controlled by trade winds, and it is dry in hot and dry seasons. The tropical monsoon returns to the east, and the dry rain comes from Xia Feng in winter.

Note: the tropical monsoon climate is distributed in the eastern part of the mainland between north latitude 100 and the tropic of cancer; The main reason is the north-south movement of pressure belt and wind belt. Tropical desert reappears three years of high temperature and rain. Note: The tropical desert climate is distributed between the Tropic of Cancer and 300 degrees north and south latitude. Controlled by subtropical high or trade winds, it is dry and rainy all year round. Mediterranean Sea, Three Four Xixia, Warm Rain in Winter Note: The Mediterranean climate is distributed on the west coast of the mainland between 300 and 400 latitude, and it is controlled by subtropical high in summer, which is hot and dry; Winter is controlled by the westerly belt, which is warm and rainy. Temperate Ocean 46 Xixia is cool in winter and warm in water. Note: The temperate maritime climate is located on the west coast of the mainland between 400 and 600 north latitude, and westerly winds prevail all the year round; Cool in summer and warm in winter; The monthly precipitation is even. Returning to March 5th in different seasons, it is rainy in the east, rainy in summer and warm in winter. Remarkable attention: the thermal difference between land and sea is the main reason for the formation of subtropical monsoon climate, which is mainly distributed on the east coast of the mainland between the tropic of Capricorn and 350 north latitude. It is hot and rainy in summer, mild and rainy in winter, with obvious seasonal changes. Warm monsoon, looking for hot rain in summer in the east and cold dry injection in winter: the difference between land and sea is the main reason for the formation of temperate monsoon climate, which is mainly distributed on the east coast of the mainland between latitude 350 and 550. It is hot and rainy in summer and cold and rainy in winter. The temperate continental climate is distributed in the middle and high latitudes and is controlled by continental air masses all the year round, with less precipitation and large temperature difference. Sub-frigid zone with 50-70 north latitude, with long and cold winters and warm and humid summers: the climate of coniferous forest in sub-frigid zone is between 500-700 north latitude, with long and cold winters and short and warm and humid summers. Cold tundra, north ice bank ice sheet, Greenland, Antarctica Note: The polar regions are dominated by downward airflow convergence, with little precipitation throughout the year. The cold tundra climate is distributed along the coast of the Arctic Ocean, and the cold ice sheet climate is distributed in the Antarctic continent and Greenland in North America. The climate type distribution area represents urban tropical rain forest climate, Congo River basin in Africa, Amazon River basin in South America, Indonesia and other places in Asia, savanna climate in Singapore, tropical desert climate in Central Africa, northern and eastern Australia, tropical monsoon climate in Brasilia, North Africa, Arabian Peninsula in Asia and desert region in Australia, tropical monsoon climate in zhina Peninsula in Asia and Mumbai in India Peninsula. Calcutta's Mediterranean climate, the Mediterranean coast, the southwestern tip of Australia and Africa, 300-400 continents of North and South America, the west coast of Rome, Athens, Marseille, Alexandria, Cape Town, Los Angeles, Santiago and Perth, subtropical monsoon climate, south of Qinling Mountains in China, North and South American continents, southeastern Australia, Shanghai, Tokyo, Sydney, temperate maritime climate, western Europe, North and South America, and zonal west coast. Temperate continental climate, inland areas of Asia, Europe and North America, Moscow, Chicago, temperate monsoon climate, East Asia, North China, Northeast China, Russian Far East, Japan and North Korea Peninsula, Beijing sub-frigid climate, North Asia and North America-tundra climate, Asia and Europe and North America-Arctic coast-ice sheet climate, Antarctic continent and Greenland-alpine climate, alpine plateau, Qinghai-Tibet plateau and Andes-(2 Asia's missing climate: savanna climate, temperate maritime climate. Asia's unique climate: tropical monsoon climate and temperate monsoon climate. The distribution range of various climates on the west coast of North and South America is limited to the coastal strip, forming the distribution characteristics of north-south extension and north-south alternation. The main reason is that the climate zone cannot extend eastward due to the limitation of Cordillera mountain system, which occupies the west side of America from north to south. The temperate continental semi-arid climate of Patagonia Plateau in South America: the Pacific coast on the west side of the same latitude has a temperate maritime climate. The reason why the temperate continental semi-arid climate in Patagonia Plateau is formed is that the North and South Andes are located on its west side, which blocks the warm and humid westerly airflow in the west. Although Patagonia Plateau faces the Atlantic Ocean in the east, it is located on the leeward slope of the Andes and becomes the shadow area of westerlies. Due to the rain shadow effect, there is less precipitation, forming a special temperate continental climate. It is speculated that the tropical rain forest climate should be developed in eastern Africa where the equator passes, but it is about 50 N-100 s, and the East African Plateau east of 380° e, although close to the equator, belongs to the tropical grassland climate rather than the tropical rain forest climate. The annual precipitation in most areas does not exceed 1 1,000 mm, and it is only about 1 1,000 mm in some areas such as windward slope of mountain plateau and Lake Victoria. The reason is the interaction of topography, air mass and atmospheric circulation. Although far from the equator, the eastern part of Madagascar in Africa, the northeastern part of Australia, the southeastern coast of Brazil Plateau and the northeastern part of Central America have formed a tropical rainforest climate. These tropical rain forest climates (tropical maritime climate) mainly appear in the east coast of the mainland and the islands in the tropical ocean in the trade wind zone of 50-250 north and south latitudes. They are all in the windward area of the trade wind from the ocean, and the warm current flows through the sea near the east side, which, together with the uplift of the terrain, forms topographic precipitation, thus developing into a tropical marine rainforest climate. Climate of Indian Tropical Desert in South Asia: This area is thar desert, also known as Indian Desert, including the arid areas of western India and eastern Pakistan in the Indus Valley. Located in the South Asian monsoon region and the wettest in the world, Kilapanchi is located on the east and west sides of the northern plains of the Indian Peninsula, but in sharp contrast, the annual precipitation is only 75- 150 mm.
