Abstract

The climatic characteristics of tropical cyclones affecting Qingdao, China, were analyzed from the aspects of frequency, period, and intensity of the tropical cyclones and their impact on rainfall in Qingdao by referring to the Typhoon Yearbook, the tropical cyclone data of China during 1949–2020 as well as surface meteorological observations. The results showed that the frequency of tropical cyclones affecting Qingdao during 1949–2020 took on an overall decreasing trend and mostly exhibited a significant variation period of 2–4 year. Tropical cyclones with the track of turning after landfall and continuing northward after landfall accounted for 47.9%. In July, there were tropical cyclones mainly followed tracks of continuing northward after landfall, and tracks turning after landfall mostly occurred in September. The intensity of the tropical cyclones showed an overall weakening feature with distinct inter-decadal variations, and it did not change much when the northward tropical cyclones close affecting Qingdao. The different track of tropical cyclones had spatially heterogeneous, strong rainfall in Qingdao with the track of continuing northward after landfall brought the highest daily and process rainfall to Qingdao, while the tropical cyclones turning nearshore or advancing offshore before landfall had relatively little rainfall.

1949-2020 年间热带气旋不同路径的气候特征及其对青岛降雨的影响

参考《台风年鉴》、1949-2020 年中国热带气旋资料和地面气象观测资料，从热带气旋的频率、周期、强度及其对青岛降水的影响等方面分析了影响中国青岛的热带气旋的气候特征。结果表明，1949-2020 年间影响青岛的热带气旋频次总体呈减少趋势，且大多呈现 2-4 年的显著变化周期。登陆后转向、登陆后继续北上的热带气旋占 47.9%。7 月，热带气旋主要遵循登陆后继续北上的路径，登陆后转向的路径多出现在 9 月。热带气旋强度总体呈减弱特征，年际变化明显，当北上的热带气旋接近影响青岛时，强度变化不大。不同路径的热带气旋在青岛的降雨空间分布不均，登陆后继续北上的热带气旋给青岛带来的日降雨量和过程降雨量最大，而登陆前转向近岸或向近海推进的热带气旋降雨量相对较小。
