Hydrological rhythm refers to the periodicity of the lake's water regime and changes in rhythm. Generalized hydrological rhythm includes day and night, monthly transport, seasonal and interannual rhythms. Under normal circumstances, due to the stability of the basin climate and underlying surface, the average water level of the lake for many years The stable value is the normal annual average water level of the lake. Therefore, the interannual rhythm of the lake is characterized by the abruptness driven by disturbance factors and the stability of the stage after adaptation to disturbance. Rhythm refers to the monthly rhythm and seasonal rhythm. Based on the above definitions, Which of the following narrow hydrological rhythms are designed:. ['Poyang Lake is affected by the continuous decrease of rainfall and the decrease of incoming water, and the water surface area continues to shrink.', 'Hongze Lake historical average annual water temperature 16.3.', 'The annual rainfall of Dongting Lake was 1,560 mm, of which about half of the precipitation was from April to June.', 'The annual average temperature of the Chaohu Lake Basin is stable between 15-16 degrees, with a frost-free period of more than 200 days. The highest water temperature is in September and the lowest water temperature is in January.']
