Comparison of climate between Houston and Xi 'an.

The climate of Houston is a typical subtropical monsoon climate, which is humid all year round.

The geographical location of Houston's climate. Houston is a bay in the southern United States, close to the Gulf of Mexico, so it belongs to the subtropical monsoon climate as a whole and has obvious subtropical monsoon climate characteristics. Summer is very hot and rainy, but in winter, it will become very warm and the climate is very pleasant. Because it is close to the ocean, the sea breeze will blow water vapor from the sea surface to the land, so Houston is wet and rainy all year round.

Solar terms in Houston's climate. Summer in Houston is very long. Houston is always in summer, and from May to October is the beginning of the year. During this period, uninterrupted rainfall and high temperature made the temperature in Houston reach an unprecedented state. In early September, the temperature will be as high as 40 degrees for several days. So people in Houston rarely choose to go out to play in summer. The long summer inevitably leads to a very short winter, but this short winter has become a good opportunity for people to visit Houston. Appropriate temperature and humidity make the whole tour more refreshing and pleasant. Of course, it does not rule out that a few people spontaneously rest at home in extremely cold weather, adults do not have to go to work, and children do not have to go to school. People often say that Houston is a very people-oriented city.

Xi is a warm temperate semi-humid continental monsoon climate, with high temperature and rainy summer and a little cold and little rain in winter. The climate is mild, with four distinct seasons and moderate rainfall. The annual average temperature in urban area is 13.3C, that in Leng Yue is -0.9C, that in the hottest month is 26.4C, and the frost-free period is 232 days. Rainfall is relatively small, mainly in summer. The annual average temperature is 13.0 ~ 13.4℃, the most Leng Yue average temperature is -0.4 ~ 0.9℃, the hottest month average temperature is 25 ~ 26.6℃, and the annual extreme minimum temperature is -20.6℃ (An199565438+/kloc- July and September are two obvious precipitation peaks. The annual sunshine hours are 1983 ~ 2267 hours, and the maximum wind direction is northeast wind (Xi 'an). The main meteorological disasters during the year were drought, waterlogging, hail, strong wind, dry-hot wind and low-temperature freezing injury.

Xi 'an is located on the southern edge of the Loess Plateau in northwest China, and the urban area is located on the first, second and third steps of the Weihe River impact plain. The peaks of the Qinling Mountains lie in the south, the Jingwei Valley winds north, the Sichuan Plateau is connected and surrounded by eight waters. Qinling Mountain is rich in wildlife resources, among which giant panda, golden monkey, pronghorn and crested ibis are rare animals under special state protection. There are many kinds of wild plants in Qinling Mountain, which is an important gene bank of seed plants in China. Qinling Mountain is also the natural dividing line between the north and south of China, and it is a huge ecological reservoir in Xi 'an. From the Xi Plain to the Qinling Mountains, the annual rainfall gradually increased from 600 mm to 900 mm ... These natural ecological and environmental conditions in Xi are obviously superior to other cities in the northwest. Since ancient times, Xi 'an has dense forests, abundant water resources and humid climate, and has the most suitable natural living environment for human survival, reproduction and development. Due to the gradual transition from subtropical environment in Banpo people's period 6,000 years ago to the present warm temperate environment, according to the climatic zones, climate types and corresponding primitive natural vegetation conditions in recent thousand years, the natural environment in Xi 'an area should be warm temperate monsoon semi-humid forest environment and forest grassland environment. Compared with other western regions, this natural climate background has obvious relative advantages for the ecological construction of Xi.
