Then what is the beneficial impact and adverse impact on economic development of my country’s significant monsoon climate?

Under monsoon climate conditions, summers are humid and rainy, and winters are dry and drier. For example, the annual precipitation in Changsha is 1,390 mm, and 71% is from March to August; the annual precipitation in Nanjing is 1,031 mm, and 74% is from April to September. Under monsoon climate conditions, the amount of precipitation and the morning and evening of the rainy season are completely different. Determined by the early and late advance and retreat of the monsoon and its strength. The rainy season in Changsha is one month earlier than in Nanjing. In North China, the rainy season is only from June to August, and even only from July to August. The length of the rainy season is related to the control of the summer monsoon. In monsoon climate conditions, rainfall is extremely unstable and varies greatly from year to year. In Changsha, rainfall is twice as much in rainy years as in dry years, three times as much in Nanjing, and more than five times as much in Beijing. Therefore, under monsoon climate conditions, frequent floods and droughts are extremely detrimental to people's production and life.

The high temperature of the monsoon climate is basically consistent with the rainy period, and the rain and heat coincide with each other, which is very beneficial to the development of agriculture. Because there is sufficient rain supply when crops are growing vigorously and need water most.

The annual temperature range is large and the temperature is low in winter, which can play a certain role in reducing pests and diseases. However, due to the large seasonal and inter-annual changes in precipitation, floods and droughts often occur, which often results in reduced agricultural production.
