Climatic characteristics of Jiaozuo

Average annual temperature in Jiaozuo 14. 2- 14。 8. The sunshine lasts for 2200-2400 hours, and the frost-free period is 2 16-240 days. Henan is located in the north subtropical zone and warm temperate zone, with mild climate, abundant sunshine and precipitation, which is suitable for developing agriculture, forestry, animal husbandry and fishery. Its characteristics are: first, the transition is obvious and the regional differences are significant. Henan is located in the mid-latitude zone, and the Qinling-Huaihe line, which divides China into warm temperate zone and subtropical zone, just passes through Funiu Mountain Ridge and the main stream of Huaihe River in China. The north of this line belongs to warm temperate semi-humid and semi-arid areas, accounting for 70% of the total area of the province, and the south of this line is subtropical humid and semi-humid areas, accounting for 30% of the total area of the province. Climate has obvious transitional characteristics. Due to the influence of monsoon climate, the latitudes of north and south are different, and the topography of east and west is different. There are many heat resources in south and east, less in north and west, more in south and southeast, and less in north and northwest of Henan, so there are obvious regional differences in climate. Second, it is warm and moderate, with the advantages of north and south. Henan has a mild climate, with an annual average temperature of 12.8- 15.5℃, sunny winter in Leng Xia and distinct seasons. It has the characteristics of long winter, less rain and snow, short spring, dry and windy sand, abundant hot rain in summer, abundant sunshine in autumn and so on. Henan is located in the transition zone between warm temperate zone and subtropical zone, and the advantages of the two climatic zones, north and south, are beneficial to the growth of many plants. Third, the monsoon is remarkable and disastrous weather is frequent. Henan is bordered by the vast Eurasia in the west and the vast Pacific Ocean in the east. The temperature difference between sea and land is significant in winter and summer, and the wind direction changes obviously with the seasons. Monsoon climate is an advantage for agriculture, but it also has disadvantages, mainly instability, which is manifested in the uneven distribution of annual precipitation in time and space. Usually, the annual precipitation is mainly concentrated in summer, accounting for 45-60% of the annual precipitation, and the instability of precipitation is easy to cause drought and flood disasters.
