[Hezhou] Construction Scheme for High Temperature, Rainy Season and Winter Special Climate (Page 24)
This document is the construction plan for [Hezhou] special climate in high temperature, rainy season and winter (24 pages), including: information overview: Hezhou City is located in the east of Guangxi, at the junction of Guangxi, Guangdong and Hunan provinces, adjacent to Qingyuan City and Zhaoqing City of Guangdong Province in the east, in the middle subtropical zone, in the south of the subtropical zone, with mild climate and subtropical monsoon climate, with an annual average temperature of 19.9 ℃, The highest temperature is in July, with an average of 28.7 ℃. The annual extreme maximum temperature is 40.9 ℃ (July 23, 2003). The lowest temperature is in January, with an average of 9.4 ℃. The annual extreme minimum temperature is - 4.0 ℃ (January 15, 1963). The average frost free period is 299 days, with the longest of 333 days and the shortest of 247 days. Due to the influence of the Pacific monsoon circulation, the rainfall in the whole region is abundant, ranging from 1500 mm to 1900 mm. However, the regional distribution is uneven. For example, Guiling and Lisong in the north have an annual rainfall of 1800 mm, while Babu and Liantang in the central plain have less annual rainfall of about 1600 mm due to the absence of high mountains; The Xindu Plain in the south is rainy all the year round, with an average annual rainfall of 1700mm. At the same time, the annual distribution of rainfall is also quite different. May is the peak period of rainfall, followed by June to August. 70% of the annual rainfall is concentrated in April to August, so there is often a process of continuous spring rain, heavy rain and flood in early summer, obvious autumn drought, and insufficient winter rain. The average rainy days for many years in the region are 169 days. The average annual evaporation in our district is 1626.6 mm, and the maximum annual evaporation is 1752.1 mm. The annual evaporation is the largest in July and the smallest in February.
