Climatic characteristics

Ganzhou, also known as Gannan, is located at the intersection of Wuyi Mountain Range, Nanling Mountain Range and Luo Xiao Mountain Range, which belongs to the southern edge of subtropical zone and has a typical humid monsoon climate in subtropical hilly areas. The four seasons are distinct, the light and heat are sufficient, the growing period is long, the temperature changes significantly, and the precipitation is abundant but unevenly distributed. There are not only favorable conditions for developing large-scale agriculture, but also climatic factors such as drought, waterlogging and low temperature that are not conducive to agricultural production.

Climatic characteristics of four seasons

Spring: rainy, disasters constantly. From March to May, cold and warm air flows frequently meet in southern Jiangxi, and the weather is changeable, sometimes cold and sometimes hot, with continuous rain. Once the cold and warm air currents are violently opposed, there may be severe weather such as thunderstorms, strong winds, hail and heavy precipitation. According to statistics, from March to May, the average number of rainy days in the city was 55 days, with a total rainfall of 628 mm, and there were 40 stations in severe weather such as gale, hail and rainstorm. There are many rainy days and heavy rains, and the frequency of disaster weather is the highest in all seasons. In addition, continuous low-temperature rain often occurs during spring sowing, which is unfavorable for early rice sowing and seedling raising.

Summer: waterlogging first, then drought, less heat. In early summer, the whole city is in the southwest airflow on the edge of subtropical high, with sufficient water vapor. Encounter cold air, heavy rainfall, easy to concentrate. In June, the city's average rainfall was 254.3 mm, and the highest monthly rainfall 1968 reached 534.2 mm, the highest in the whole year. The average rainstorm 17 station this month is the main flood season in our city, which is the most prone to flood disasters. From July to September, controlled by the western Pacific subtropical high or continental high, it is mostly sunny and hot, and only affected by typhoon or easterly wave can a large precipitation process occur. Due to the uneven distribution of precipitation, high temperature and large evaporation, there are different degrees of drought every year, and there is no soaking rain in some years or even dozens of days, which seriously harms agricultural production. In midsummer July and August, the highest temperature in the central basin during the day is generally above 36℃, but the temperature in the morning and evening is generally below 30℃. Although it is hot during the day, it is not so hot. Surrounded by mountains, the average temperature in the hottest July is less than 28.5℃, and the climate is cool.

Autumn: sunny and sunny. 10-165438+1about a week in the middle of October, it is often controlled by high pressure from north to south, with stable atmospheric stratification and fine weather. The monthly average rainy days are only 6-8 days, the monthly average temperature is 14-2 1℃, and the monthly average relative humidity is 70-80%, which is the least rainy season in the whole year.

Winter: cold but not cold, with little rain and snow. The latitude in southern Jiangxi is low, and there are mountains in the north to stop cold air from driving directly south. It is late in winter and has little freezing damage. Often controlled by the dry and cold air mass in the north, few clouds and rain form. During the day, the sun is shining and the temperature is high; Radiation cooling at night, the temperature can drop below zero, forming frost and ice. When attacked by a strong cold wave, it can produce solid precipitation or freezing weather, but the probability is very small, and the average annual snowfall days are only 1-2 days.

Topography Ganzhou is located at the junction of Nanling Mountain, Wuyishan Mountain and Zhuguang Mountain, with high terrain around and low middle. The landform is dominated by hills and mountains, accounting for 83% of the city's land area.
