1, climate and environment. Seen from the climatic environment, the latitude of Qingdao is 35 35 ′-37 09 ′ north latitude, which belongs to temperate monsoon climate. Because of its high latitude, the temperature in autumn is lower than that in low latitude areas, while the typhoon trudges from south to north and gradually weakens with the decrease of temperature and water vapor. So in Qingdao, the intensity of the typhoon became lower, making people unaware of the arrival of the typhoon.

2. Terrain. From the landform observation, on the one hand, the overall topography of Qingdao presents a relatively closed topography with high east and low west, low depression in the middle and uplift on the north and south sides; On the other hand, Qingdao relies on Shandong, a special landform with mountains and hills as the skeleton and staggered plains and basins, which has a blocking and weakening effect on typhoons.
