Why does Guizhou's climate have a good resource advantage?

Guizhou is located in the subtropical west of China, on the slope of Yunnan-Guizhou Plateau, and belongs to subtropical monsoon climate. The eastern half is in the southeast monsoon region which is wet all year round, and the western half is in the transition zone from the southeast monsoon region without obvious dry and wet seasons to the southwest monsoon region with obvious dry and wet seasons. Because it is located at low latitude and high altitude, close to the ocean, the east, south and north directions of the central part of the territory show an upward trend and gradually decline, and it spans the Sichuan Basin, Chongqing Mountains, Hills and Guangxi Hills, with mountains and rivers criss-crossing, which makes the terrain very complicated, thus forming the complexity and diversity of the climate. Although the climate in most areas is mild and humid, the vertical change of climate in mountainous areas and river valleys is particularly obvious. In winter half a year, due to the blocking of Qinba Mountain system in the north, cold air from the south mostly intrudes around the two lakes basin from the northeast, often forming a static front in the central and western regions. Weining and Panxian areas in the west are often in front of the front, so the winter is sunny, and the central and eastern parts of the province are just behind the front, so it is rainy in winter. Summer is controlled by subtropical high, and it is often sunny and dry in the east, but there are frequent rainstorms in the west. The subtropical high jumps northward, and the rain belt also moves northward. At this time, drought and flood alternate in the province.

The average temperature in Leng Yue (65438+ 10 month) is usually 3℃ ~ 6℃, which is higher than other areas in the same latitude. The average temperature in the hottest month (July) is generally 22℃ ~ 25℃. The annual average precipitation is1100 ~1400 mm, and the annual relative humidity is above 70%.

The climate is characterized by four distinct seasons, mild winds in spring, no severe cold in winter, no heat in summer, abundant rainfall, rainy and hot seasons, cloudy and less sunshine, high humidity, rainy days, obvious monsoon climate, long frost-free period, great vertical difference and obvious three-dimensional climate. In summer, there are many breezes in the whole province. Under the natural adjustment of the forest, the cool breeze blows gently, and no matter how hot it is, it is not boring. It is a rare sub-plateau resort in China. As far as the humidity in Guizhou is concerned, there are more rainy nights (sunny days), and the forests in the whole province have a good effect on maintaining water vapor. After it rains at night, it evaporates a little during the day. Generally, the most suitable humidity condition for human body is between 45% and 70%, and the average humidity in summer in Guizhou is about 65%, which is very suitable for people to travel, that is, they will feel very refreshing wherever they go. According to scientific research, when the ambient climate is between 18℃ and 24℃ and the air humidity is between 45% and 70%, the human body feels most comfortable. Obviously, Guizhou has both, and it lasts all summer. Influenced by the warm and humid airflow in Guizhou, Jingfeng in Yunnan and the Bay of Bengal, the weather in Guizhou is wet and cold in summer and cloudy in daytime, which greatly reduces the invasion of ultraviolet rays, so that visitors to Guizhou are not injured or tanned, and women's skin is fair and tender, while men's skin color is moderate and healthy.

Second, the types of climate resources

The special zone has created a particularly pleasant climate in Guizhou. The climate in Guizhou spans two climatic zones from north to south, namely temperate zone and subtropical zone, which can be divided into four types: south subtropical zone, middle subtropical zone, north subtropical zone and warm temperate zone. The south subtropical zone is mainly distributed in Luodian and Wangmo in the south of Guizhou and Chishui in the north. ≥ 10℃ accumulated temperature is greater than 6000℃; The average temperature in Leng Yue is greater than10℃; The annual extreme minimum temperature is greater than -5℃. The subtropical zone is mainly distributed at ≥ 10℃, with a product of 4500-6000℃; The average temperature in Leng Yue is 4-10℃; The annual extreme minimum temperature is-10-5℃. The northern subtropical zone is mainly distributed at ≥ 10℃, and the accumulated temperature is 3500-4500℃. The average temperature in Leng Yue is 2-4℃; The annual extreme minimum temperature is -20- 10℃. The warm temperate zone is mainly distributed in high altitude areas in the west and mountainous areas such as Fanjing Mountain and Leigong Mountain. ≥ 10℃ accumulated temperature is less than 3500℃; The average temperature in Leng Yue is less than 2 C; The annual extreme minimum temperature is less than -20℃.

Third, the advantages of climate resources.

Guizhou has no heat in summer, cool in spring and cool in autumn, humid air and abundant rainfall. Summer is one of the coolest places in the same latitude of the earth. Superior climate resources have bred beautiful natural scenery in Guizhou and created a pleasant tourist environment. At present, the forest coverage rate in the province is 39%, with green mountains and green waters, beautiful scenery, mild climate and distinct seasons. Very suitable for sightseeing, leisure and vacation. In spring and summer, the monthly precipitation in the whole province is100-150 mm. Abundant precipitation not only makes the streams and rivers in the mountainous areas of the whole province keep flowing, but also makes the karst mountainous areas more colorful with the changes of sunny and rainy days.

1, meteorological landscape

1) light image in the atmosphere. Light mainly refers to sunlight and moonlight, including sunrise, rising sun, sunset, rainbow, halo and China. , is a light image with ornamental value.

2) Rain and snow landscape. In the process of natural precipitation, clouds, fog, rain, snow and other landscapes can be produced.

3) Meteorological landscape related to wind. Visitors can feel its beauty through their senses. Such as "Spring Breeze Willow", "Red Maple Autumn Moon" and "Miao Ling Songtao" will give people a comfortable and pleasant feeling.

2. Meteorological types

1) summer climate: Guizhou summer tourist areas can be divided into three types: mountain type A, such as Fanjing Mountain, Leigong Mountain and Cape Mountain; B lakeside type, such as Weining Caohai, Hongfeng Lake and Baihua Lake; C plateau type, such as Longli grassland, has no heat in summer and becomes a summer resort.

2) Climate of rainy night and sunny day: June-September is rainy night and sunny day in Guizhou, which is good for rest and sightseeing.

3. Meteorological and climatic characteristics

1) The physical phenomena and processes in the changeable and rapidly changing atmosphere often change endlessly. The so-called "four seasons in one mountain" and "different days in ten miles" all illustrate the variability of meteorological climate, which is reflected in fog, rain, lightning, light and other elements. Sunrise, sunset and other typical scenes, tourists can only enjoy the beautiful scenery if they seize the opportunity.

2) Although the background and meteorological elements of scenic spots have direct ornamental value, in many cases, they are not as specific and rich as landforms, nor as intuitive and experienced as waterscapes and flowers and trees, so they often become the background for people to appreciate other landscapes and make use of them. In addition, meteorological climate also has the function of adapting and cultivating scenery, that is, under different climatic and climatic conditions, different natural landscapes and tourist environments can be formed, and meteorological climate has the function of cultivating scenery.

3) Rhythm and Orientation Due to the periodic change of climate year by year, tourism activities also have rhythm changes in off-season and peak season and the guiding law of passenger flow with climate change. For example, in summer, people in hot areas move to areas with cool temperatures on the plateau; In winter, people in cold areas move to places with warm sunshine. This kind of passenger flow guidance law is the result of climate rhythm change.

4. season

1) Spring in Guizhou is from March to May. Spring has come, all the trees are alive, all the flowers are in full bloom, and all the places are full of vitality. In spring, the light, temperature and precipitation increase synchronously, and plants flourish and trees flourish. Especially after the beginning of the spring rain, rivers and lakes overflow, trees grow tender leaves, and green mountains and green waters are all reflected in it. This is the best time for people to go for an outing.

2) Summer

The summer in Guizhou is from June to September, and the weather is sunny and mild. The sunshine time is long during the day, the temperature is mild at night, and the daily temperature difference is large.

3) Autumn

Autumn in Guizhou is from June 65438+ 10 to February 65438+February. Although the temperature is lower than that in summer, the weather is still good. The native plants in this province are evergreen plants, but many deciduous trees have also been introduced. Colorful leaves adorn the beautiful scenery of Guizhou in autumn.

4) Winter

The winter in Guizhou is 65438+ 10 to February. The temperature drops in most parts of the province, but there is no severe cold, which is still a good season for tourism.
