Why is there a drought in Shandong?

hello, landlord! \xd\ To answer this question, we must first look at the geographical location of Shandong Province. \xd\ Shandong Province is an important province along the eastern coast of China, located in the lower reaches of the Yellow River, bordering the Bohai Sea and the Yellow Sea in the east, facing the Korean Peninsula and the Japanese archipelago across the sea, bordering Hebei Province in the northwest, Henan Province in the southwest and Anhui and Jiangsu provinces in the south. Shandong Peninsula is opposite to Liaodong Peninsula and surrounds Bohai Bay. \xd\\xd\ Special geographical location makes Shandong Province become the intersection of the Yellow River Economic Belt and the Bohai Economic Zone, the junction of North China and East China, and occupies an important position in the national economic structure. \xd\ xd \ Secondly, \ xd \ Shandong Province is between 34 degrees 25 minutes and 38 degrees 23 minutes north latitude and 114 degrees 36 minutes and 112 degrees 43 minutes east longitude, with the longest east-west distance of about 7 kilometers and the widest north-south distance of 42 kilometers, with a total land area of 156,7 square kilometers, accounting for about 1.6% of the country's total area, ranking 19th in the country. The topography of Shandong Province is a part of the Great Plain of North China, in which the central part is a raised mountain, the eastern and southern parts are gentle hilly areas, and the northern and northwestern parts are flat alluvial plains of the Yellow River. The highest point in Shandong Province is Mount Tai in the middle, with an altitude of 1,545 meters. The lowest point is the Yellow River Delta in the northeast, with an altitude of 2 to 1 meters. The topography of Shandong Province is dominated by plains and hills, and plains and basins account for about 63% of the total area of the province. Mountains and hills account for about 34%; Rivers and lakes account for about 3%. Rivers and lakes crisscross in Shandong Province, with dense water networks, and there are more than 1 rivers with a main stream of more than 5 kilometers long. The Yellow River, known as the "mother river of the Chinese nation", obliquely crosses the Shandong territory from southwest to northeast, with a flow of more than 61 kilometers, and enters the sea from Bohai Bay. The famous Beijing-Hangzhou Grand Canal runs through the Luxi Plain from southeast to northwest, with a length of more than 63 kilometers. Other important rivers include Tuhai River, Majia River, yi river River, Shuhe River, Dawen River, Xiaoqing River, Jiaolai River and Huaihe River. The larger lakes in Shandong are Nansi Lake and Dongping Lake. Nansi Lake consists of Weishan Lake, Zhaoyang Lake, dushan lake Lake and Nanyang Lake, with a total area of 1,375 square kilometers, making it one of the top ten freshwater lakes in China. The main mountain ranges in Shandong are Taishan, Mengshan, Laoshan, Lushan, Yishan, Culai, Kunyu, Jiuding, Ai Shan, Yashan, Daze and Meng Lianggu. \xd\ Shandong Province belongs to the warm temperate and semi-humid monsoon climate zone, with mild climate and distinct four seasons. The average annual temperature in the province is 11-14 degrees, the average annual precipitation is 55-95 mm, and the frost-free period is more than 18 days in coastal areas and more than 22 days in inland areas. \xd\ The main reason of "nine droughts in ten years" in Shandong since ancient times is the lack of precipitation. \xd\ Shandong's climate belongs to temperate continental monsoon climate, with concentrated precipitation, rainy and hot seasons, short spring and autumn, and long winter and summer. \xd\ Shandong has a long sunshine time throughout the year, with an annual sunshine time of 2,3-2,9 hours. The heat condition can meet the needs of two crops a year. However, more than 6% of precipitation is concentrated in summer, so it is easy to form floods, and droughts often occur in winter and spring, which has the greatest impact on agricultural production. \xd\ In addition, it is also due to the influence of the geographical environment where Shandong is located-Shandong Province is located in the middle latitude, adjacent to the Yellow Sea and Bohai Sea in the east, with a coastline of 324.4 kilometers from Dakou River in Wuli County in the north to Xiuzhen River in Rizhao County in the south. Shandong Peninsula in the east, protruding between the Yellow Sea and the Bohai Sea, has the Kunyu Mountain Range across the peninsula. The inland is connected with the Great Plain of North China. There is Taiyi Mountain in the middle of Shandong Province, and the main peak Taishan (1545 meters) is the highest point in the province. The mountain situation in the whole province is high in the northwest and low in the southeast. Due to the influence of land and sea distribution and topographical characteristics, strong winds in Shandong occur frequently, with strong intensity and long duration, and become one of the main disastrous weather.
